Updates the GitHub Actions workflow (`.github/workflows/docker-publish.yml`)
to build and push Docker images for both `linux/amd64` and `linux/arm64`
architectures.
The `platforms` attribute has been added to the `docker/build-push-action`
step for both the backend and frontend jobs. This ensures that you on
different CPU architectures can use the published images from ghcr.io.
Adds a GitHub Actions workflow to automatically build and publish Docker images for the backend and frontend services.
The workflow (`.github/workflows/docker-publish.yml`) is triggered on pushes to the `main` branch. It includes two jobs:
1. `build_and_push_backend`: Builds the Docker image from `surfsense_backend/Dockerfile` and pushes it to `ghcr.io/<owner>/surfsense_backend:<commit_sha>`.
2. `build_and_push_frontend`: Builds the Docker image from `surfsense_web/Dockerfile` and pushes it to `ghcr.io/<owner>/surfsense_web:<commit_sha>`.
Both jobs include steps for:
- Checking out the repository.
- Setting up QEMU and Docker Buildx.
- Logging into the GitHub Container Registry (ghcr.io) using `secrets.GITHUB_TOKEN`.
- Building and pushing the respective Docker images, tagged with the commit SHA.
- Adding OCI labels for image source, creation date, and revision.
This CI pipeline automates the process of creating and distributing Docker images for the application, ensuring that new versions are available in the GitHub Container Registry upon changes to the main branch.
