# QuadletGen

> Browser-local Docker Compose and Docker Run to Podman Quadlet systemd unit converter.

QuadletGen (`https://quadletgen.com`) converts `compose.yaml` service stacks and `docker run` or `podman run` CLI commands into declarative Podman Quadlet files (`.container`, `.network`, `.volume`, and `.env`) for `systemd` on Linux. Every parse, SELinux bind mount relabel (`:z` and `:Z`), secret extraction, and `.zip` archive export runs locally inside the user's browser with zero server uploads and zero container count limits.

## Capabilities

- Parses multi-service Docker Compose YAML (`services`, `volumes`, `networks`, `ports`, `environment`, `depends_on`, `healthcheck`, `restart`, `devices`, `cap_add`, `cap_drop`, `labels`, `user`, and `command`).
- Translates single-container `docker run` and `podman run` shell invocations into standalone `.container` units.
- Targets both rootless (`~/.config/containers/systemd/` with `systemctl --user`) and rootful (`/etc/containers/systemd/` with `sudo systemctl`) install scopes.
- Applies SELinux volume relabeling (`:z` shared or `:Z` private) for Fedora, RHEL, CentOS Stream, Fedora CoreOS, and Universal Blue hosts.
- Separates sensitive environment keys into a companion `.env` file wired via `EnvironmentFile=`.
- Bundles all generated Quadlet unit files into a downloadable `<stack>-quadlet.zip` archive.
