GitHub CI/CD for Snoop Docker Images

Automating Docker builds and pushes to Docker Hub with GitHub Actions involves configuring workflows that use Docker Buildx to build images and push them automatically when changes are merged to the main branch or new tags are created.

Yes, you can build multi-platform Docker images for amd64 and arm64 architectures within a GitHub Actions workflow by utilizing Docker Buildx to support simultaneous linux/amd64 and linux/arm64 image creation.

GitHub Actions cache speeds up Docker image builds by storing intermediate build layers and reusing them across subsequent workflow runs, reducing the time needed to construct backend and frontend service images.

You do not need Kubernetes to use GitHub Actions for building Docker images; the workflow operates within GitHub Actions and pushes images directly to Docker Hub, although the resulting images are suitable for Kubernetes deployments.

The best way to trigger a Docker image push to Docker Hub on a new Git tag is to configure a GitHub Actions workflow that automatically builds and pushes the backend and frontend images whenever a new Git tag is created.

GitHub Actions Docker builds for arm64 architecture require proper multi-platform configuration using Docker Buildx; without enabling cross-platform support for linux/arm64, the build may fail when attempting to create images for different architectures.
