CI/CD with GitHub Actions: Build and Deploy Docker to a Server

Why use Actions for Docker?

GitHub Actions provides easy integration with repositories, secrets and runners. We demonstrate a minimal pipeline to build, push and deploy images securely.

Example Workflow

name: CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Build image
[...]

Secure Secrets and Deploy Keys

Use repository secrets for registry credentials and a deploy key with limited privileges for SSH access. Rotate keys regularly.
