## 📦 Container Registry

### GitHub Container Registry (GHCR)

**Where Images Are Stored:**
```
ghcr.io/{owner}/timetracker
```

**Who Can Access:**
- ✅ Public repositories: Anyone (if package is public)
- ✅ Private repositories: Authenticated users with access

**Authentication for Users:**
```bash
# Using GITHUB_TOKEN (for users)
echo $GITHUB_TOKEN | docker login ghcr.io -u USERNAME --password-stdin

# Using GitHub CLI
gh auth token | docker login ghcr.io -u USERNAME --password-stdin

# In CI/CD (automatic)
# No manual authentication needed!
```

**No Docker Hub Needed:**
- ✅ All images hosted on ghcr.io
- ✅ Free for public repositories
- ✅ Included with GitHub account
- ✅ No external registry fees
