# GitHub Actions Docker Publishing Setup
This repository includes a GitHub Actions workflow that automatically builds and publishes Docker images to Docker Hub.
## Workflow Overview
The workflow (`/.github/workflows/publish-docker.yml`) automatically:
1. **Builds** the Docker image using multi-platform support (AMD64 and ARM64)
2. **Publishes** to `sillyangel/mice`
3. **Tags** images appropriately based on git refs
4. **Caches** layers for faster subsequent builds
5. **Generates** build provenance attestations for security
## Trigger Conditions
The workflow runs on:
- **Push to main/master branch** → Creates `latest` tag
- **Push tags** (e.g., `2025.07.02`) → Creates date-based version tags
- **Pull requests** → Creates PR-specific tags for testing
- **Manual dispatch** → Can be triggered manually from GitHub UI
## Image Tags Generated
Based on different triggers, the workflow creates these tags:
### Main Branch Push
- `sillyangel/mice:latest`
### Tag Push (e.g., `2025.07.02`)
- `sillyangel/mice:2025.07.02`
- `sillyangel/mice:latest`
### Pull Request
- `sillyangel/mice:pr-123`
## Multi-Platform Support
The workflow builds for multiple architectures:
- `linux/amd64` (Intel/AMD 64-bit)
- `linux/arm64` (ARM 64-bit, Apple Silicon, etc.)
## Usage After Setup
Once the workflow is set up:
1. **Push to main** → New `latest` image published
2. **Create a release** → Versioned images published
3. **Users can pull**: `docker pull sillyangel/mice:latest`
## Manual Image Building
You can also build and push manually:
```bash
# Build for multiple platforms
docker buildx build --platform linux/amd64,linux/arm64 \
-t sillyangel/mice:latest \
--push .
# Login first (if needed)
echo $DOCKERHUB_TOKEN | docker login -u USERNAME --password-stdin
```
