CI/CD Pipeline with ArgoCD, Jenkins, and Helm for Kubernetes: A Step-by-Step Guide

1. Developer Workflow

• Commits Code:A developer writes and commits application code to a source code repository (e.g., GitHub, GitLab, or Bitbucket).
• Changes Config:The developer also modifies Kubernetes configuration files, such as Helm charts or Kubernetes manifests, which are stored in a version-controlled repository.

2. CI Pipeline (Continuous Integration)

• Code Build and Image Creation:A CI pipeline is triggered when new code is committed to the repository. This pipeline includes:Building the Code: Tools like Jenkins, CircleCI, or GitLab CI are used to compile and test the code.Creating a Container Image: Once the code passes the tests, a container image is built using tools like Docker.Push Image to Repository:The newly created container image is pushed to an image repository (e.g., DockerHub, Amazon Elastic Container Registry, or another container registry).This image becomes the deployable artifact for the application.

3. CD Pipeline (Continuous Deployment)

• Configuration Management:
• ArgoCD Sync:

• ArgoCD, a declarative GitOps tool, continuously syncs the changes from the configuration repository.
• ArgoCD ensures the Kubernetes clusters are always aligned with the desired state defined in the configuration repository.
• It uses Helm charts or raw Kubernetes manifests to define the application's desired state and infrastructure configuration.
