EKS GitOps in One Repo: Build, Deploy, Promote, and Rollback with Argo CD

Description

In this video, I walk through a practical GitOps workflow on AWS EKS using a single repository. Infrastructure and Argo CD are already set up, so this focuses on the real delivery flow: Infrastructure overview (with diagram) Helm chart template structure Build image for simple-app-01 Push image to ECR with correct naming and version Deploy to staging with Argo CD Manually promote to production Add a dark mode change and release again Roll back to a previous stable state via Git change Apply the same pattern to other apps This setup shows the convenience of controlling multiple apps and both staging/production flows from one GitOps repo.
