Cloud Training Program

Kubernetes cluster is used to deploy a containerized application on Cloud. One of the ways to deploy a containerized application in the form of Kubernetes Cluster on OCI is Container Engine for Kubernetes.

Kubernetes Adoption in Cloud:

AWS – Elastic Kubernetes Service (EKS)
Microsoft Azure – Azure Kubernetes Service (AKS)
Google Cloud Platform – Google Kubernetes Engine (GKE)
Oracle Cloud – Oracle Kubernetes Engine (OKE)
Digital Ocean – Digital Ocean Kubernetes Service (DOKS)

Key Concepts Of Kubernetes

1) Kubernetes cluster: Is a group of nodes and nodes are the machine that runs the application. A node can be a physical machine or virtual machine.

2) Container: A container is a run time instance of a docker image that contains three things docker image, execution environment, and a standard set of instructions. There are different types of containers like Linux Container, Rocket, Mesos Containers, and Docker.

3) Type of nodes and their processes

Master Node:
- kube-apiserver: supports API operations using Kubernetes Command Line tool (kubctl)
- kube-controller-manager: to manage kubernetes components (like: replication controller, endpoint controller, namespace controller)
- kube-scheduler: where in the cluster to run jobs
- etcd: store clusters configuration data

Worker Node
- kubelet: to communicate with master node
- kube-proxy: handles networking

4) Pods: A worker node comprises various containers, Kubernetes groups the containers in a single logical unit called pods. Pods specify the process running in the Cluster. Similar functioning pods can be grouped together called a service.

5) Manifest Files/ Pod specs: These files are in json or yaml format that specifies how to deploy applications on node or nodes.

6) Node pools: It enables to create pools of machines in a cluster with different configurations like one Node pool for virtual machines and one for bare-metal machines. A cluster must have at least one node pool and it need not contain any worker node.

Ways To Launch Kubernetes On Oracle

There are basically three methods to run Kubernetes on OCI

Roll-your-own Container Management: Using OCI component to create a Kubernetes Cluster and deploying container runtime like Docker, Kubernetes, Mesos. (Do it yourself model)
Quickstart Experience: Automated model with terraform to build components of Kubernetes cluster (terrform on github).
Container Engine for Kubernetes: OKE is the manageable service in OCI used for deploying Kubernetes cluster within a few steps.

Container Engine for Kubernetes is a highly available and manageable service in Oracle Cloud Infrastructure (OCI). It is used to deploy Cloud Native applications in OCI. We can create an application using Docker Containers and then deploy them on OCI using Kubernetes. Kubernetes groups the application containers into logical units called pods. We can manage the Container Engine for Kubernetes using API or Console.

We can create by default three clusters (Monthly flex costing model) or one cluster (pay as you go costing model). In each cluster, we can have a maximum of 1000 nodes, a maximum of 110 pods can run on each node.

Why Use Kubernetes

why use kubernetes

Traditional deployment was costlier as we need to have a different physical server for the deployment of each application otherwise if we deploy multiple applications on each server than there will be a problem of resource allocation to each application.
Virtualized Deployment is the solution to the above problem, in this, we can host multiple virtual machines on a physical server & will provide isolation to the applications deployed on each Virtual Machine. It also provides better utilization of resources.
Container Deployment is similar to VMs but shares the OS among different applications, therefore, it is considered as lightweight. Containers are a good way to integrate and run your applications. For eg: if a container goes down then another container should start working and this process should be handled by a system.

Access Kubernetes On Oracle Cloud

1) Creating a Kubernetes Cluster: We can create a kubernetes cluster in OCI using various methods like

Using console (quick cluster)
Custom setting in console (custom cluster)
Using API

To know about the steps to create the Kubernetes cluster click here.

2) Modify: We can modify the already created cluster node details.

3) Delete Cluster: We can delete cluster when it is of no use along with master node, worker nodes, and node pools.

4) Monitoring Cluster: We can monitor the cluster and associated nodes for its overall status. Cluster status can be creating, active, failed, deleting, deleted, and updating.

5) Accessing Cluster: We can use kubctl command-line tool to access and perform operations on the cluster.

Benefits Of Using Oracle Kubernetes (OKE)

Easy to build & maintain applications and economics.
Easy to integrate Kubernetes with registry using OKE.
Feasible for developers to deploy and manage container applications on cloud.
Combine open-source container orchestration of Kubernetes with oracle services like control, IAM, security, etc.

This post is the second video of our five-part video series on “Docker & Kubernetes”.

In this video blog, we are covering the Architecture & Components of Docker and Container lifecycle.

Note: If you have missed my previous post on “Docker vs Virtual Machine”, to check previous post click here https://k21academy.com/docker12

<Video>

Docker Architecture & Components

Docker uses a client-server architecture. The docker client talks to the Docker daemon, which used to building, running, and distributing the Docker containers. The Docker client and daemon communicate using a REST API, over UNIX sockets, or a network interface.

Docker Architecture

There are five major components in the Docker architecture:

a) Docker Daemon listens to Docker API requests and manages Docker objects such as images, containers, networks, and volumes.

b) Docker Clients: With the help of Docker Clients, users can interact with Docker. Docker client provides a command-line interface (CLI) that allows users to run, and stop application commands to a Docker daemon.

c) Docker Host provides a complete environment to execute and run applications. It comprises of the Docker daemon, Images, Containers, Networks, and Storage.

d) Docker Registry stores Docker images. Docker Hub is a public registry that anyone can use, and Docker is configured to use images on Docker Hub by default. You can run your own registry on it.

e) Docker Image read-only templates that you build from a set of instructions written in Dockerfile. Images define both what you want your packaged application and its dependencies to look like what processes to run when it’s launched.

Note: To know more about Docker image in detail click here

Resources Isolation In Container (Docker)

a) Namespace provides a layer of isolation. namespace limits what you can see. When we run a container, Docker creates a set of namespaces for that container. There are different types of namespace pid, net, mnt, uts, ipc.

b) Control groups limit an application to a specific set of resources. it limits how much resources you can use. This allows Docker Engine to share available hardware resources to containers and optionally enforce limits and constraints.

c) Union file systems that operate by creating layers, Docker image is made up of filesystems layered over each other making it very lightweight and fast.
If you didn’t have UnionFS, a 200MB image runs 5 times as 5 separates containers would mean 1GB of disk space.

Docker Engine Components

Docker Engine is the layer on which Docker runs. It is installed on the host machine. It’s a lightweight runtime and tooling that manages containers, images, builds, and more.

Docker Engine Components

There are three components in the Docker Engine:

a) Server: It is the docker daemon called dockerd. It can create and manage docker images. i.e. Containers, networks.

b) Rest API: It is used to instruct docker daemon what to do.

c) Command Line Interface (CLI): It is a client that is used to enter docker commands.

Docker Networking & Storage

Networking in Docker is part of docker which is used to connect the docker container to each other and outside world so they can communicate with each other also they can talk to Docker Host. you can connect docker containers to non-Docker workloads. Docker uses CNM Container Network Model for networking.

Note: To know more about Docker networking in detail click here

Docker Storage By default, all files created inside a container are stored on a writable container layer so the data doesn’t persist when that container no longer exists. Docker has two options for containers to store files in the host machine, so that the files are persisted even after the container stops: volumes, and bind mounts.

Container Lifecycle

There are different stages when we create a container which is known as Lifecycle of container i.e create, run, pause, delete & stopped.

The first phase is the created state. Further, the container moves into the running state while we use the Docker run command.
we can stop or pause the container, using Docker stop/pause command. And, to put a container back from a stopped state to a running state, we use the Docker run command.
We can delete a running or stopped container, using rm command.

In this blog post, we’ll cover Topic 3.4 Microsoft Azure Governance which includes Azure Blueprints & Azure Policy.

Microsoft Azure provides governance features and services in order to implement policy-based management for all Azure services available on-cloud and on-premise. The two most prominent services are:

Azure Blueprints
Azure Policy

Azure Blueprints

Azure Blueprints like architectural blueprints, define Azure resources that implement an organization’s standards, patterns, and requirements.
By leveraging Azure Blueprints, engineers can quickly build and deploy new environments.
Azure Blueprints provides a mechanism that allows you to create and update artifacts (like policies, RBAC, resource group, ARM templates) and assign them to environments and version them.

RBAC is Azure’s role-based access control, a system that provides access management of Azure resources. Using Azure RBAC, one can segregate duties within the team and grant only the amount of access to users that they need to perform their role.

Azure Policy

Azure Policy is a service that you use to create, assign, and manage policies.
These policies enforce rules on resources so those resources stay compliant with your corporate standards and service-level agreements.
Policies enforce tagging for resources and resource groups and restrict regions for deployed resources.

Sample Questions

Here are a few sample questions from the Microsoft Azure Fundamentals Certification Exam[AZ-900] that you should be able to solve after reading this blog.

Q 1: You have a resource group named RG1. You plan to create virtual networks and app services in RG1. You need to prevent the creation of virtual machines only in RG1. What should you use?
A. a lock
B. an Azure role
C. a tag
D. an Azure policy
Correct Answer: A
References:https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-lock-resources

Q 2. Your company has an Azure environment that contains resources in several regions. A company policy states that administrators must only be allowed to create additional Azure resources in a region in the country where their office is located. You need to create the Azure resource that must be used to meet the policy requirement. What should you create?
A. a read-only lock
B. an Azure policy
C. a management group

This blog covers the topic 3.5 Azure Cloud Security: Monitoring and Reporting which includes Azure Cloud Monitor & Azure Cloud Service Health.

Monitoring is one of the key aspects of any IT environment, and proper reporting of events can lead to an on-time response to any problems that may arise.

Azure Cloud Monitor

Azure cloud monitor is an extensive solution for the collection, analysis, and action on the telemetry data it collects from the enterprises’ cloud and on-premises environment.
It also enables us to figure out how well the applications are performing and identifies issues affecting them and the resources they are dependent on.
Listed below are some of the key points about the service:
The Azure Monitor has insights from all the Azure cloud solutions which lead to a very handy collection of user activity logs, diagnostic logs, storage logs, and compute logs. Hence making sure no activity or error goes unnoticed.
A cloud environment by nature is highly distributed, meaning that at any single moment there can be multiple sources generating telemetry data. The Azure Monitor’s ability to aggregate and process that data allows the user to create alerts for issues with potential business impacts in the Azure environment.

Azure Monitor

Azure Cloud Service Health

The Azure Cloud provides a suite of services that keep you informed about the health of all your cloud resources in the form of Azure Service Health.
The information that is provided includes things such as service impacting events, planned maintenance, and various other changes that may affect the availability of your cloud resources.
The Azure Service Health is a combined suite of three smaller services listed below:

Azure service health: the main module that provides you with personalized information on the services and regions being used by you.
Azure Status: provides information on service outages, in case of a service outage from Azure’s side this can help an enterprise to quickly migrate its resources temporarily to non-impacted regions or plan its cloud deployments keeping previous service outages in mind.
Azure resource health: provides information regarding the health of your individual resources such as a specific virtual machine instance.

Azure Service health

Sample Questions

Here is a sample question from the Microsoft Azure Fundamentals Certification Exam[AZ-900] that you should be able to solve after reading this blog.

Q1. Which of the following statements are true?

From Azure Service Health, an administrator can view the health of all the services deployed to an Azure environment and all the other services available in Azure.
From Azure Service Health, an administrator can create a rule to be alerted if an Azure service fails.

Planning to be a Microsoft Certified: Azure Solutions Architect Expert but confused about the certification process? In this blog, I will be covering all the differences between the two exams AZ-300: Microsoft Azure Architect Technologies and AZ-301: Microsoft Azure Architect Design along with the recommended path you should follow to crack this certification.

Starting with the most important detail about these exams, both exams need to be cleared to attain the Azure Solutions Architect Expert certification and are not interchangeable with each other. The topics for the AZ-300 exam are geared more towards technical proficiency in the Azure cloud with a more hands-on approach whereas, the AZ-301 exam is geared more towards designing solutions and strategies related to various Azure services and has a more theoretical approach.

AZ-300: Architect Technologies Exam Details

Certification Name: [AZ-300] Microsoft Azure Architect Technologies
Prerequisites: There are no prerequisites for taking this course. Microsoft recommends candidates to have a minimum of six months of hands-on experience administering Azure.
Exam Cost: USD 165.00

Candidates for this exam should have subject matter expertise in designing and implementing solutions that run on Microsoft Azure, including aspects like compute, network, storage, and security.

Although Microsoft does not list any prerequisites for this exam, due to the highly technical nature of this AZ-300 exam candidates are advised to go through the [AZ-900] Microsoft Azure Fundamentals and the [Az-104] Microsoft Administrator certification exams.

AZ-300: Exam Topics

Microsoft AZ 300 syllabus

The important domains covered in the [AZ-300] Microsoft Azure Architect Technologies certification exam are:

Deploy and configure infrastructure (40-45%)
Implement workloads and security (25-30%)
Create and deploy apps (5-10%)
Implement authentication and secure data (5-10%)
Develop for the cloud and for Azure storage (15-20%)

As we can see here, The topics for the AZ-300 exam are geared more towards technical proficiency in the Azure cloud with a more hands-on approach and includes labs to prepare the candidates for real-world scenarios.

AZ-301: Architect Design Exam Details

Certification Name: [AZ-301] Microsoft Azure Architect Design
Prerequisites: There are no prerequisites for taking this course. Candidates are recommended to have a minimum of six months of hands-on experience administering Azure.
Exam Cost: USD 165.00

Candidates for this exam are Azure Solution Architects who advise stakeholders and translate business requirements into secure, scalable, and reliable solutions.

Similar to the AZ-300, Microsoft does not list any prerequisites for this exam but being an Architecture Design exam, candidates have to be familiar with the basic workings of the Azure cloud and be proficient in managing the cloud as well and hence are advised to go through the [AZ-900] Microsoft Azure Fundamentals and the [Az-104] Microsoft Administrator certification exams.

AZ-301: Exam Topics

Microsoft Architect design learning Path

The important domains covered in the [AZ-301] Microsoft Azure Architect Design certification exam are:

Determine workload requirements (10-15%)
Design for identity and security (20-25%)
Design a data platform solution (15-20%)
Design a business continuity strategy (15-20%)
Design for deployment, migration, and integration (10-15%)
Design an infrastructure strategy (15-20%)

It can be observed from the above exam topics that this exam is focused more on the designing of solutions and strategies related to various Azure services. This exam has a more theoretical approach rather than a hands-on one.

Which Exam To Go For First?

Both of these certifications are required for earning the Microsoft Certified: Azure Solutions Architect Expert Badge, However candidates are recommended to go through the [AZ-300] Azure Architect Technologies certification first and then focus on the [AZ-301] Azure Architect Design certification as the hands-on knowledge gained from AZ-300 would be immensely helpful in bringing clarity to the theoretical Designs of the AZ-301 exam.

OCI Registry (OCIR) is an Oracle-managed registry that simplifies your development by making it easy for you as a developer to store, manage and deploy container images, like Docker images securely within an Oracle Cloud.

Let’s start with an overview and use cases of Registry.

Overview of OCI Registry (OCIR)

OCIR is a highly available and scalable private container registry service for storing and sharing container images within the same regions as the deployments.

An integrated platform offering, where users can store their container images easily in one location. Access to push and pull images with the Docker CLI or images can be pulled directly into a Kubernetes deployment.

These container images are managed and deployed on the Container Engine for Kubernetes (OKE).

oci registry

Use cases of OCI Registry

OCIR can be used as a private Docker registry for internal use, pushing and pulling Docker images to and from the Registry using the Docker V2 API and the standard Docker command-line interface (CLI).
OCIR can also be used as a public Docker registry, any user with internet access, and knowledge of the appropriate URL can pull images from public repositories in OCIR.
Developers, testers, and CI/CD systems need to use a registry to store images created during the application development process. You can iterate on code faster and push it to production more frequently.
Oracle Functions and Events. The function code is packaged as a Docker image and pushed to OCIR and the event triggers can be configured in Events service to make sure when the function is invoked.

Benefits of OCI Registry

Integration: Full integration with Container Engine for Kubernetes (OKE)
Security: Registries are private by default but can be made public by an admin
Regional Availability: Pull container images quickly from the same region as your deployments
High availability: Leverages OCI for high performance, high availability, and low latency image push and pull
Anywhere Access: Use Docker CLI to push and pull images from anywhere – cloud, on-premises, or laptop

Pre-requisites for OCIR

User must have access to an Oracle Cloud Infrastructure tenancy.
User must have access to the Docker CLI
To use registry service, the user is either a part of the admin group or part of a group to which a policy grants
the appropriate permissions
User needs to have an OCI username and auth token before being able to push/pull an image

Steps to configure OCI Registry

1. Navigate to Auth Tokens, under Resources and click Generate Token

Generate Auth token

2. Copy the token created, it will be used as password for accessing OCIR.

Auth token generated

3. Install Docker CLI on the local machine (windows in my case). Follow the steps for installation given here

4. Pull the hello-world image from Docker Hub and run it in the CLI.

docker run hello-world

5. To list image downloaded from Docker Hub, enter the following command

  docker images

6. Login to the registry in OCI using Docker CLI

In a terminal window on the client machine running Docker, enter the following command
```
docker login <region-key>.ocir.io
```

Enter your username and password

Username: <tenancy-namespace>/<username>
If tenancy is Federated with Oracle Identity Cloud Service
Username: <tenancy-namespace>/oracleidentitycloudservice<username>
Password: Auth token generated earlier (not visible)

7. Locate the existing image hello-world that we downloaded in step 4 to push

In a terminal window, enter the command
```
docker images
```
Tag the image that you are going to push to the registry. In our case, we are going to push the image named hello-world.
```
docker tag <image-identifier> <target-tag>
```

tag docker image

8. Push your tagged docker image from the local machine to OCI registry

   docker push <target-tag>

push docker image

9. Pull the Docker image from OCI registry to the client machine

docker pull <region-key>.ocir.io/<tenancy-namespace>/<repo-name>/<image-name>:<tag>

Note: Docker images can be pulled with Docker CLI or directly into Oracle Container Engine for Kubernetes(OKE) Deployments. We have demonstrated using only the Docker CLI in this post.

10. We can see by navigating to the Registry created in OCI that the image is pushed into the hello registry

OCI Pushed Image

11. We can see the pull status from OCI console

Nowadays, It is critical for organizations to keep track of Billing and Cost Management of various services(Compute, Database, Storage, Networking, IAM) in OCI.

Oracle Cloud Infrastructure provides Cost Analysis, Budgets, and Usage Reports through which you can analyze your spendings on different services, keep track of services used, and set a threshold on your spending.

In this blog, we will discuss a suite of tools Oracle provides to help you understand spending patterns, monitor consumption, analyze their bill, and, ultimately, reduce spending.

Pricing Models

Oracle offers several purchase models to help you maximize the potential from cloud services while optimizing the cost at the same time.

pricing model

Pay-as-you-go (PAYG): Allows you to quickly provision services with no commitment, and pay only for what you use.
Universal Credits-Monthly Flex: Select a monthly prepaid commitment and can consume any IaaS and PaaS cloud service anytime, anywhere.
Bring your own license: Bring your current on-premise Oracle software licenses to equivalent, highly automated Oracle IaaS & PaaS services in the cloud.

In a nutshell, these are the three pricing models that Oracle provides. Read more about the pricing models here.

Benefits of Cost Management

Cost Management Benefits

Oracle Cost Management provides various enterprise-grade controls to maintain control over cloud cost:

Predictability: Budgets ensure predictable cloud spending and prevent over usages.
Control: Quotas help you centrally control usage of high-value cloud resources
Visibility: Cost Analysis Dashboard help maintain visibility over the spending. Usage reports also help gain insight into resource-level visibility.
Optimization: Ability to perform cost optimization and lower spend.
Extensibility: Lets you leverage cloud management and BI tools you already know and use.

Pre-requisites

User must have access to an Oracle Cloud Infrastructure tenancy
To use registry service, the user is either a part of the admin group or part of a group to which a policy grants
the appropriate permissions

Steps to Configure

OCI Cost Analysis

Cost Analysis is a visualization tool that helps understand spending patterns at a glance. To use this tool, user must be a member of the Administrators group. Cost Analysis filters cost by Date, Tags, and Compartments.

cost management dashboard

Use the Cost Analysis dashboard to view your spending by service or by department, compartment, or cost tracking tag.

1) In Start Date, select a date. In End Date, select a date (within six months of the start date). Click Apply Filters

filter by date

2) From Tag Key, select a tag. Click Apply Filters

filter by tag

3) From Compartment, select a compartment. Click Apply Filters

filter by compartment

OCI Budgets

Budget is used to track actual spending for the whole tenancy or per compartment. It is also used to set alerts on your budgets at predefined thresholds to get notified.

The following concepts are essential for budgets:

Budget: A monthly threshold you define for your cloud spending.
Alert: Email alerts that get sent out for your budget

1) Navigate to Budgets in OCI Console and click on Create Budget

create budget

2) Sample Budget Alert Emails

budget alert email

OCI Usage Reports

A usage report is a comma-separate value (CSV) file contains detailed information about your OCI resources consumption. It is generated daily and stored in an object storage bucket.

It can be used in conjunction with your rate card for:

Invoice reconciliation
Custom reporting
Cross-charging
Cost optimization
Resource inventory

Sample Dashboard from a Usage Report

Usage report dashboard

Read more about Usage Reports https://k21academy.com/oci46.

Service Limits and Usage

When you sign up for Oracle Cloud Infrastructure, a set of service limits are configured for your tenancy. The service limit is the quota or allowance limit on a resource. Your tenancy’s limits, quotas, and usage can be seen in the Console. Service limits can be increased from within the Console after submitting a request.

Service Limits

Compartment Quotas

Quotas give you better control over how resources are consumed by letting you allocate resources to projects or departments. Compartments help you restrict usage to a small set of resources, restrict resource counts or disable services as necessary. Similar to Service Limits; but service limits are set by Oracle, and compartment quotas are set by administrators.

compartment quotas

Oracle Cloud Workload Cost Estimator

Oracle launched Oracle Cloud Workload Estimator last month which shows a drastic difference between the computing scenarios of Oracle Cloud Infrastructure and AWS.

This tool offers an apples-to-apples comparison of key workloads between Oracle Cloud infrastructure and that of AWS. You will be amazed to see the results that show “Oracle is a more cost-efficient option for many high-performance applications.”

To know more about Oracle Cloud Workload Estimator, check here.

Cost Management Best Practices

Let’s take a look at some best practices for cost management:

Create a budget that matches your commitment amount and an alert at 100 percent of the forecast. This gives you an early warning if your spending increases and you’re at risk of getting an overage.
Use compartments for cost management along with access-control. Many customers set up one compartment per department for cost management and cross-charging.
Use cost-tracking tags (like cost-center) to allocate costs in more granular ways.
Enable monitoring on all resources. Monitoring data can be merged with cost data to gain powerful insights on how to improve resource utilization.
Usage reports are also used to analyze costs and drive custom solutions.

This post is the third video of our five-part video series on “Docker & Kubernetes”.

In this video blog, we are going to cover the Kubernetes architecture, Kubernetes components, Managed Kubernetes Service Also, we are discussing what is Kubernetes master node & worker node and it’s components.

Note: If you have missed my previous post on “Docker Architecture | Docker Engine Components | Container Lifecycle”, to check previous post click here https://k21academy.com/docker13

<Video>

What Is Kubernetes?

In organizations, multiple numbers of containers running on multiple hosts at a time so it is very hard to manage all the containers together we use Kubernetes. Kubernetes is an open-source platform for managing containerized workloads and services. Kubernetes takes care of scaling and failover for your application running on the container.

Note: know more about the containers(Docker) & Kubernetes

Kubernetes Architecture Key Points

1) In Kubernetes architecture, there is one or more master and multiple nodes. One or masters used to provide high-availability.

2) The master node communicates with nodes using API-server to kublet communication.

3) In the worker node, there are one or more pods and pods contain one or more containers.

4) Containers can be deployed using the image also can be deployed externally by the user.

Kubernetes Components

Kubernetes Master Node

Master Node is a collection of components like Storage, Controller, Scheduler, API-server that makes up the control plan of the Kubernetes. When you interact with Kubernetes by using CLI you are communicating with the cluster’s Kubernetes master. all the processes run on a single node in the cluster, and this node is also referred to as the master. There can be more than one master node in the cluster.

Master Node Components

1) Kube API-server performs all the administrative tasks on the master node. A user sends the rest commands as YAML/JSON format to the API server, then it processes and executes them. The Kube API-server server is the front end of the Kubernetes control plane.

2) etcd is a distributed key-value store that is used to store the cluster state. Kubernetes stores the file in a database called the etcd. Besides storing the cluster state, etcd is also used to store the configuration details such as the subnets and the config maps.

3) Kube-scheduler is used to schedule the work to different worker nodes. it also manages the new requests coming from the API Server and assigns them to healthy nodes.

4) Kube Controller Manager the task of the Controller is to obtain the desired state from the API Server. if the desired state does not meet the current state of the object, then the corrective steps are taken by the control loop to bring the current state the same as the desired state.

There are different type of control manager in Kubernetes such as

Node Manager, it manages the nodes. it creates new nodes if any node unavailable or destroyed.
Replication Controller, It manages if the desired number of containers is running in the replication group.
Endpoints controller, it populates the endpoints object that is, joins Services & Pods.

Kubernetes Worker Node

The worker nodes in a cluster are the machines or physical servers that run your applications. The Kubernetes master controls each node. there are multiple nodes connected to the master node. On the node, there are multiple pods running and there are multiple containers running in pods.

Worker Node Components

1) The kubelet is an agent that runs on each worker node and communicates with the master node. It also makes sure that the containers which are part of the pods are always healthy. It watches for tasks sent from the API Server, executes the task like deploy or destroy the container, and then it reports back to the Master.

2) Kube-proxy is used to communicate between the multiple worker nodes. it maintains network rules on nodes also it makes sure there are necessary rules define on the worker node so the container can communicate to each in different nodes.

3) Kubernetes pod is a group of one or more containers that are deployed together on the same host. Pod is deployed with a shared storage/network, and a specification for how to run the containers. Containers can easily communicate with other containers in the same pod as though they were on the same machine.

4) Container Runtime is the software that is responsible for running containers. Kubernetes supports several container runtimes: Docker, containers.

Managed Kubernetes Service

In Kubernetes, both the master node and worker nodes are managed by the user. But in managed Kubernetes service third-party providers manage Master node & user manages Worker node also manage Kubernetes offers dedicated support, hosting with pre-configured environments. Managed solutions take care of much of this configuration for you.

In this blog post, we are going to cover the most common question we got in our FREE webinar Kubernetes vs Docker and Docker Limitations. Docker is a platform as a service(paas) product that is used to use applications on containers and Kubernetes is a container orchestration platform used to manage multiple containers.

Note: Watch our five-part video series on “Docker & Kubernetes” in these series we covered topics Docker vs Virtual Machine, Docker Architecture, Kubernetes Architecture, Kubenrtees high availability, Q/A Docker & Kubernetes.

<Video>

What is docker?

Docker is an open-source platform based on Linux containers for developing, shipping, and running applications inside containers. we can deploy many containers simultaneously on a given host. Containers are very fast and lightweight because they don’t need the extra load of a hypervisor because they run directly within the host machine’s kernel.

What is Kubernetes?

Note: know more about the containers(Docker) & Kubernetes

Kubernetes vs Docker

A fundamental difference between Kubernetes and Docker is that Kubernetes is meant to run across a cluster while Docker runs on a single node. Docker is the most popular container platform and Kubernetes is a platform for managing containerized workloads. Kubernetes can work with any containerization technology. Kubernetes helps with networking, load-balancing, security, and scaling across all Kubernetes nodes which runs your containers.

Docker Limitations

a) Dynamic IP: The problem with docker is it uses dynamic IP address. When we restart the container the IP address will change because IP is not static in Docker.

b) Ephemeral data storage: In docker storage, we have Ephemeral storage, not persistence storage due to this all of the data inside a container disappears forever when the container shuts down.

c) Confined to Single Host: In Docker, we can multiple containers on different hosts. Inside a single host we can connect multiple containers to each other via a bridge network but we can’t connect two containers that are running on different hosts.

When you are designing an infrastructure the first thing you need is an architecture diagram. There are various tools that can be used to build an OCI Architecture diagram like Visual Paradigm, Draw.io graphics, Cacoo template, OKIT and many more. These tools are really helpful in understanding and preparing an OCI infrastructure diagram. These diagrams are a great way to represent the overall design, deployment and topology and provide a bird’s eye view on the architecture.

From all the tools mentioned above, OKIT might be the best as it was released recently and offers much more than the other tools. In this blog, we will be discussing:

Overview of OKIT
Interface of OKIT
Steps to Install OKIT
Accessing OKIT from your browser
Creating a Custom Template

Overview Of OKIT

OCI Designer ToolKIT (OKIT) is an Open-Source browser-based Design tool for OCI which provides a very fast designing of a complete OCI based Infrastructure. It is a Drag and Drop application through which admins can prepare an OCI based Infrastructure and can also export it in Ansible / Terraform scripts.

It is a graphical environment through which you can create and visualize OCI environments by using your web browser. The interface is extremely simple and easy to use which makes it fast to deploy and use. It allows designers or architects to visualize and create an infrastructure and then let them export in different formats such as:

svg
png
jpeg

This toolkit can further be used to add key property information to the build infrastructure which can further be exported to different frameworks like:

Ansible
Terraform
OCI Resource Manager

Interface Of OKIT

The OCI Designer ToolKIT provides a simple and minimalistic interface which can be divided into three parts.

Palette

It is present on the left side of the screen on which you have access to different OCI artefacts. These icons can be dragged and dropped into Canvas to build an infrastructure.

Canvas

Present on the center of the screen where the infrastructure diagram is built. Initially, it will only have a compartment and you will have to drag and drop artefacts from the palette.

Properties

On the right side of the screen, we have Properties slide-out panel through which you can edit the properties if the selected artefacts which will then be implemented when we export them for different frameworks.

Steps To Install OKIT

Step 1: Connect to your instance(on which you want to install OKIT) using PuTTY.

Step 2: Install Git using the below commands:

$ sudo yum install -y git

Git Install

Step 3: Install Docker using the below commands:

$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2
$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
$ sudo yum install -y docker-ce
$ sudo systemctl start docker

Docker Install

Step 4: Install CLI using the below command:

$ bash -c "$(curl -L https://raw.githubusercontent.com/oracle/oci-cli/master/scripts/install/install.sh)"

Installing CLI

When prompted for Install directory and every other resource path, Press Enter (choose default).

When prompted for ‘Y/N’ for $Path, Enter Y, when prompted for path for rc file Press Enter (choose default).

Once it is installed, check the OCI CLI Version by typing:

 $ oci -v

Step 5: Now we need to configure OCI to create OCI config file. Use the below command

$ oci setup config

When prompted for directory press ENTER (choose Default) then paste the OCID of user, tenancy and then write the region.

Press Y and then Enter when asked for new API Signing Key. Leave directory, name and passphrase empty.

This will configure the OCI config file.

Now add the newly created public key into API keys present under your User.

Step 6: Clone OCI Designer toolkit form Git using the below command:

$ git clone -b v0.5.1 --depth 1 https://github.com/oracle/oci-designer-toolkit.git

Once it has been cloned, change directory to oci-designer-toolkit and build the Docker image using these commands:

$ cd oci-designer-toolkit
$ sudo docker build --tag okit --file ./containers/docker/Dockerfile --force-rm ./containers/docker/

You will get output like this

Step 7: Once all the above steps are done, just run the docker image we just build by using the below command:

$ sudo docker run -d --rm -p 80:80 \
           --name okit \
           --hostname okit \
           -v ~/.oci:/root/.oci \
           -v `pwd`/okitweb:/okit/okitweb \
           -v `pwd`/visualiser:/okit/visualiser \
           -v `pwd`/log:/okit/log \
           okit

Running this command will give you an output as shown below:

This completes the installation of OKIT on your Linux Instance in OCI.

Note: The above command can be used with -it instead of -d, running a docker image with -it starts the server interactive so when you close the command it shuts down. The -it is useful for seeing the server errors / whats happening accessing http://localhost/okit/designer will display the designer and if not you should see the error where the command is running.

Accessing OKIT From Your Browser

Once you have configured OKIT on your instance you just need to check if your Security List allows it to connect to it.

So, go into you OCI account and Security List of your Public Subnet and add an Ingress Rule as shown below:

Once you have added this Rule, you can now access it from your Local machine’s Browser from the below URL:

http://<Instance’s Public IP>/okit/designer

OKIT

Creating A Custom Template

OKIT lets you build and save a custom template. Creating a template is very easy and fast using this toolkit. Let’s take an example of Load Balancer front-ending a pair of instances.

Select “New” from the menu and Use the Drag & Drop features of OKIT to create the following architecture.

You can now save the diagram and it will be available to resue.

Kubernetes cluster is used to deploy containerized applications on the cloud. Kubernetes uses the same underlying infrastructure, OS, and container. In this post, we are going to cover all about Amazon EKS (Elastic Kubernetes Service) used to deploy applications on AWS.

Cloud Vendors adopted Kubernetes in different ways.

AWS – Elastic Kubernetes Service (EKS)
Microsoft Azure – Azure Kubernetes Service (AKS)
Google Cloud Platform – Google Kubernetes Engine (GKE)
Oracle Cloud – Oracle Kubernetes Engine (OKE)
Digital Ocean – Digital Ocean Kubernetes Service (DOKS)

Containers & Kubernetes

Containers are a software package into an invisible box with everything that the application needs to run. Docker containers are built off Docker images.

To know about the difference between Docker & Virtual machine click here https://k21academy.com/docker12

Kubernetes is an open-source platform for managing containerized workloads and services. Kubernetes takes care of scaling and failover for your application running on the container.

To know the difference between Kubernetes and Docker click here http://k21academy.com/kubernetes16

Overview Of EKS

Amazon EKS is a managed service that is used to run Kubernetes on AWS. Using EKS users doesn’t have to maintain a Kubernetes control plan on their own. It is used to automate the deployment, scaling, and maintaining the containerized application. It works with most of the operating systems.

EKS is integrated with various AWS services:

ECR (Elastic Container Registry) for container images.
Elastic Load Balancer for distributing traffic.
IAM for providing authentication and authorization.
VPC (Virtual Private Cloud) for isolating resources.

Benefits Of Using EKS

No setup required to configure Kubernetes on AWS.
In this users need not create a control plan.
Worker nodes are also managed by Amazon EKS
EKS integrates with various AWS tools.

Note: Using ECR we have to manage the underlying OS, infrastructure, and container engine but using EKS we only have to provide containerized application, and rest is managed by EKS.

Components Of EKS

1) Nodes: A node is a physical or virtual machine. In EKS both Master Node and Worker Node are managed by EKS. There are two types of nodes.

Master Nodes: These are responsible for the control plan of Kubernetes Cluster and managed by EKS
- API Servers: It controls the API servers whether it is kubctl (Kubernetes CLI) or rest API.
- etcd: It is a highly available key-value store that is distributed among the Kubernetes cluster to store configuration data.
- Controller Manager: It makes sure that you are using as much as the container needed at a point of time. It keeps a count of containers used and also records the state.
- Scheduler: It validates that what and when the work needs to be done. It integrates with the Controller manager and API servers.

Worker Nodes: It is responsible for the Data plan of the Kubernetes environment.
- kublet: It controls the flow to and fro from the API. It makes sure containers are running in the pod.
- kubproxy: It includes networking rules and access control. It is like a firewall.

components of kubernetes

2) Pods: A group of containers is called pods. They share networking, storage, IP address, and port spaces.

3) DaemonSet: It makes sure that all node runs a copy of a certain pod. It is like a monitoring tool.

4) Job: It tracks and establishes the state of individual work.

EKS Workflow

eks workflow

Provision EKS cluster using AWS Console, AWS CLI, or one of the AWS SDKs.
Deploy worker nodes to the EKS cluster. There is already a predefined template that will automatically configure nodes.
Now we configure Kubernetes tools such as kubctl to communicate with the Kubernetes cluster.
We are now all set to deploy an application on the Kubernetes cluster.

EKS Pricing

Though the pricing of various services in AWSis dynamical, so it is recommended to check the pricing before deploying clusters.

As a standard, we have to pay 0.10$ /hour for each Amazon EKS cluster and we can deploy multiple applications on each EKS cluster. We can run EKS using either EC2 or AWS Fargate, and on-premises using AWS outposts.

This blog gives a step by step walkthrough of implementing CICD in an Azure environment using YAML and pipelines.

You can visit our previous blog to know more about the [AZ-400] Microsoft Azure DevOps certification.

What Is An Azure DevOps Environment?

An environment is a collection of resources that can be targeted by deployments from a pipeline. Environments can include Kubernetes clusters, Azure web apps, virtual machines, databases. Typical examples of environment names are Dev, Test, QA, Staging, and Production.

The advantages of using environments include the following.

Deployment history — Pipeline name and run details are recorded for deployments to an environment and its resources. In the context of multiple pipelines targeting the same environment or resource, the deployment history of an environment is useful to identify the source of changes.
Traceability of commits and work items — View jobs within the pipeline run that target an environment. You can also view the commits and work items that were newly deployed to the environment. Traceability also allows one to track whether a code change (commit) or feature/bug-fix (work items) reached an environment.
Diagnose resource health — Validate whether the application is functioning at its desired state.
Permissions — Secure environments by specifying which users and pipelines are allowed to target an environment.

How To Setup DevOps Environment In Azure

Step 1: Sign in to our Azure DevOps organization and navigate to our project.
Step 2: In our project, navigate to the Pipelines page. Then choose Environments and click on Create Environment.

Environment creation

Step 3: After adding the name of an environment (required) and the description (optional), we can create an environment.

Step 4: Resources can be added to an existing environment later as well.

Step 5: Then we can get started by add this newly added environment into the YAML code.

Step 6: Once after we added that environment into the YAML pipeline, we need to start running it.

Step 7: We can see the multiple environments as part of this YAML, basically, we are adding the CICD into the YAML file.

Step 8: From the above environment, we can see the below deployment happened successfully

Step 9: Now after this we can log in to the Azure portal and then check if the below deployment is successful or not.

Step 10: Now when we click on the below URL, we can see the basic build and deployment of the “HELLO WORLD” application as a sample NodeJS.

Using Approval Checks

We can also manually control when a stage should run using approval checks. You can use approval checks to control deployments to production environments.

Checks are a mechanism available to the resource owner to control when a stage in a pipeline consumes resources.

As the owner of a resource, such as an environment, we can define approvals and checks that must be satisfied before a stage consuming that resource starts. Currently, manual approval checks are supported by environments.

We can control who can create, view, use, and manage the environments with user permissions. There are four roles — Creator (scope: all environments), Reader, User, and Administrator. In the specific environment’s user permissions panel, we can set the permissions that are inherited and we can override the roles for each environment.

Navigate to the specific Environment that you would like to authorize.
Click on the overflow menu button located at the top-right part of the page next to “Add resource” and choose Security to view the settings.
In the User permissions blade, click on +Add to add a user or group and select a suitable Role.

Azure DevOps Pipeline | How To Use

Pipeline permissions can be used to authorize all or selected pipelines for deployment to the environment.

To remove Open access on the environment or resource, click the Restrict permission in Pipeline permissions.
To allow specific pipelines to deploy to an environment or a specific resource, click + and choose from the list of pipelines.

This is the basic YAML CICD pipeline without any environment resources such as VM’s or Kubernetes pods. But that said, we can also do the same way for the other resources as well.
