Source Code demo series videos về Google Kubernetes Engine & DevOps | Lưu trữ Kubernetes Manifest Files, sử dụng Kustomize với GitHub Action Workflow để deploy. Action Secrets được Provision bởi Terraform Code.

Using GitHub Action Workflow kustomize

Workflow .github/workflows/deploy.yaml

This Workflow will need to be triggered manually after merging Pull Requests.

Pull Requests will be created when you build container images in Frontend and Backend Repositories

• https://github.com/p-le/devops-todoapp-backend/blob/main/.github/workflows/build.yaml
• https://github.com/p-le/devops-todoapp-frontend/blob/main/.github/workflows/build.yaml

Steps:

1. Authenticate to GCP Project using Workload Identity Feature
2. Authorize to target GKE Cluster
3. Install Kustomize
4. Apply Kubernetes Manifest Files. Replace value using sed

Migration to Helm Chart

Note: IMO, Kustomize's template feature does not support provide variables dynamically.

That's why I used sed command to replace values in Manifest Files as a workaround.

I've decided to use Helm Chart with ArgoCD.
