In the vast landscape of container orchestration, Kubernetes stands tall as a powerhouse, streamlining deployment, scaling, and management of containerized applications. In this blog post, we are going to cover How to Install Minikube,. Kubectl, Docker and jenkins on Ubuntu 22.04 LTS AWS EC2 Instance.

System Requirements for Minikube and Jenkins:

Minimum 2 CPU’s or more
Minimum 2GB of free memory
Minimum 20GB of free disk space
Internet connection

Create t2.medium aws ec2 instance with 20GB ebs volume to perform installation.

Install JDK on AWS EC2 Instance:

Install java on ec2 instance using below commands:

				
					sudo apt-get update
sudo apt install openjdk-11-jre-headless -y
java --version

Install and Setup Jenkins:

Install and setups server using below commands:

				
					sudo curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key | sudo tee   /usr/share/keyrings/jenkins-keyring.asc > /dev/null
sudo echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc]   https://pkg.jenkins.io/debian-stable binary/ | sudo tee   /etc/apt/sources.list.d/jenkins.list > /dev/null
sudo apt-get update
sudo apt-get install jenkins
sudo systemctl start jenkins
sudo systemctl status jenkins

Assigning administration privileges:

				
					    sudo vi /etc/sudoers

Add the following line at the end of the file
jenkins ALL=(ALL) NOPASSWD: ALL
Open your web browser and paste http://{ ec2 instance public ip}:8080 to access the application. Wait until the Unlock Jenkins page appears.
