Hi There ! ,Here are the step-by-step details to set up an end-to-end Jenkins pipeline for a flask application using SonarQube, Argo CD, Helm, and Kubernetes:

Prerequisites:

1. Application code hosted on a Git repository

2. Jenkins server

3. Kubernetes cluster

4. Argo CD

Steps:

1. Install the necessary Jenkins plugins:

1.1 Git plugin

1.2 Pipeline plugin

1.3 Kubernetes Continuous Deploy plugin

2. Create a new Jenkins pipeline:

2.1 In Jenkins, create a new pipeline job and configure it with the Git repository URL for the flask application.

2.2 Add a Jenkinsfile to the Git repository to define the pipeline stages.

3. Define the pipeline stages:

Stage 1: Checkout the source code from Git.

Stage 2: Run SonarQube analysis to check the code quality.

Stage 3 : Check for manifest files

Stage 4 : Promote the application to a production environment using Argo CD.

Stage 5 : Update manifest files and push to repository
