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 VM must have Docker & Docker Compose installed. SSH key (with passphrase‑less access) in ~/.ssh/authorized_keys. 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).
