OpenShift and Kubernetes can improve access to hidden foundations and assist with dealing with the application lifecycle and development work processes.

Features of OpenShift

Run cloud-native microservices at scale: Microservices architecture combines inexactly coupled capabilities to make high-performing applications. The small size of these administrations makes them profoundly testable and simple to keep up with, while at the same time expanding adaptability in how applications are organized and conveyed. OpenShift makes it conceivable to make and send cloud-local microservices at scale, either to improve existing application execution or to fabricate completely new applications starting from the earliest stage.
Container Security: It has features for securing containerized applications, such as role-based access control (RBAC) and container image scaling.
Scale and manage infrastructure: The adaptable, cloud-based nature of OpenShift gives organizations unlimited authority over the scale and the executives of their application framework. Businesses can instead concentrate on application development, support, and evolution by removing concerns regarding lifecycle management, storage, and security.
Open-source and cloud-based technologies: OpenShift likewise contains a set of developer tools as order line utilities and IDE support that permit designers to compose and send to creation with expanded speed. Moreover, OpenShift incorporates a bunch of pre-made, simple-to-utilize formats that offer a basic snap interface and can be effectively modified to address your issues. It additionally works with popular continuous integration tools like Jenkins.
Support for Various Languages and Runtimes: OpenShift supports different types of programming languages and runtimes, allowing developers to use the tools and systems they are familiar with.

Prerequisites

A server running Ubuntu 20.04 on AWS
A root password is configured on your server.

Installing OpenShift on Ubuntu

Step 1: Login to AWS Console with your credentials after login.

Step 2: Launch an EC2 instance with ubuntu machine as shown in below figure.

Launching Ubuntu Virtual Machine (AMI)

Step 3: After launching an EC2 instance by using SSH connect to your into your Ubuntu host VM by using git-bash or putty orelse any another terminals.

SSH connecting to terminal

Step 4: Update system by using following commands

sudo apt update
sudo apt upgrade

Step 5: In order to run all OKD services in docker containers, you must first install the Docker CE on your system. The most recent version of Docker CE is available by default in the default repository for Ubuntu 20.04. You can introduce it simply by running the following command:

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Install Docker

Step 6: Once the Docker is installed, start the Docker service and enable it to start at boot with the following command:

systemctl start docker
systemctl enable docker

Step 7: You can also verify the status of the Docker service with the following command, this command show that docker is running or not

systemctl status docker

Status of the Docker

Here our docker is running, Now we can proceed to another step.

Download OpenShift Origin

Step 1: The latest version of OpenShift Origin is v3.11.0. You can download it from the Git Hub repository by using the wget command and paste github repository link address.

wget https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz

Step 2: Once completion of download now untar the file or extract the file by using following command

tar -xvzf openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz

untar file

Step 3: Now change the directory to the extracted directory by using cd command

cd openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit

Step 4: Copy ‘oc’ command to ‘/usr/local/bin/’ directory on the system by using following command

cp oc kubectl /usr/local/bin/

Step 5: Now check the oc installation by using following command

oc version

The following output will be shown in terminal

OC version

Step 6: Next, you will need to create a new daemon.json file and allow the use of the Insecure Docker registry.

nano /etc/docker/daemon.json

When we execute this terminal open a blank terminal in that write a script

{
     "insecure-registries" : [ "172.30.0.0/16" ]
}

Step 7: Otherwise directly execute this command in terminal directly before going to do this execution switch to root account by using following command

sudo su -

Switching to root account

Step 8: Now restart the docker to implement the changes by using following command

systemctl restart docker

Step 9: Now, start the OpenShift Origin cluster by specifying your system’s Public IP:

Here i am not exploring my public ip

oc cluster up --public-hostname=your-server-ip

Once execution complete then output shown like this

OpenShift server started.
The server is accessible via web console at:
https://ec2-.54.162.17.204-us-west-1.compute.amazonaws.com:8443
You are logged in as:
User: developer
Password: <any value>
To login as administrator:
oc login -u system:admin

This is the final Output
