What this does?

This repo along with https://github.com/saha-rajdeep/kubernetesmanifest creates a Jenkins pipeline with GitOps to deploy code into a Kubernetes cluster. CI part is done via Jenkins and CD part via ArgoCD (GitOps).

Jenkins installation

Jenkins is installed on EC2. Follow the instructions on https://www.jenkins.io/doc/tutorials/tutorial-for-installing-jenkins-on-AWS/ . You can skip "Configure a Cloud" part for this demo. Please note some commands from this link might give errors, below are the workarounds:

1. If you get daemonize error while running the command sudo yum install jenkins java-1.8.0-openjdk-devel -y then , run the commands from the answer of https://stackoverflow.com/questions/68806741/how-to-fix-yum-update-of-jenkins

2. Install Docker on the EC2 after Jenkins is installed by following the instructions on https://serverfault.com/questions/836198/how-to-install-docker-on-aws-ec2-instance-with-ami-ce-ee-update

3. Run sudo chmod 666 /var/run/docker.sock on the EC2 after Docker is installed.

4. Install Git on the EC2 by running sudo yum install git

Jenkins plugins

Install the following plugins for the demo.

• Amazon EC2 plugin (No need to set up Configure Cloud after)
• Docker plugin
• Docker Pipeline
• GitHub Integration Plugin
• Parameterized trigger Plugin

ArgoCD installation
