Notes‑App CI/CD

What’s here

• CI (ci.yml): on push/PR builds, lints & tests both services.
• CD (cd.yml): on merge to main, builds Docker images, pushes to Docker Hub, then SSHs into your VM and does a rolling docker-compose up.

Prerequisites

1. VM must have Docker & Docker Compose installed.
2. SSH key (with passphrase‑less access) in ~/.ssh/authorized_keys.
3. GitHub Secrets configured:
   • DOCKERHUB_USERNAME, DOCKERHUB_TOKEN
   • SERVER_HOST, SERVER_USER, SERVER_SSH_KEY

Usage

• Push or PR → ✅ CI runs.
• Merge into main → ✅ CD runs automatically.
• You can also manually trigger CD in the Actions tab (workflow_dispatch).
