Building Locally

Default registry: Forgejo (git.as73.inetsix.net/docker/*)

Each image has its own Makefile with dual-registry support:

# Build locally (uses Forgejo registry by default)
cd <image-directory>
make build

# Push to GitHub Container Registry
make push-github

# Push to Forgejo Container Registry
make push-forgejo

# Push to both registries
make push-all

# Override registry/namespace (example: build for GitHub)
make build REGISTRY=ghcr.io NAMESPACE=titom73 IMAGE_TAG=v1.0
