# podup

**docker-compose on rootless Podman — one static Rust binary. No daemon. No Python.**

## 📥 Install

### Debian / Ubuntu (apt) — recommended

Register the signed Glyndor repository and install — copy-paste:

```bash
curl -fsSLO https://apt.glyndor.net/glyndor-archive-keyring.deb
sudo dpkg -i glyndor-archive-keyring.deb
sudo apt update && sudo apt install podup
```

The keyring package registers `https://apt.glyndor.net` and ships the signing
key, so podup updates (and key renewals) arrive through `apt upgrade` — the apt
build omits self-update since apt owns upgrades. Signed, SHA-256 verified,
fail-closed. Requires **Podman ≥ 5.0** (rootless).

<details>
<summary><b>Other methods — Linux/macOS script · Windows · build from source · self-update · Podman version · platforms</b></summary>

### apt, one-liner (script)

Same as above via the install script (registers the repo, then installs):

```bash
curl -fsSL https://glyndor.net/podup/install/unix | bash -s -- --apt
```

### Linux / macOS (install script)

```bash
curl -fsSL https://glyndor.net/podup/install/unix | bash
```

### Windows (PowerShell)

```powershell
irm https://glyndor.net/podup/install/windows | iex
```

Both installers verify the Ed25519 signature over `SHA256SUMS` and fail closed
otherwise.

### Build from source

```bash
cargo build --release
```

### Self-update

```bash
podup update            # download and install the latest signed release
podup update --check    # report whether a newer release exists, install nothing
```

`podup update` replaces the running binary in place only after verifying the
release's Ed25519 signature and SHA-256 checksum — it fails closed otherwise. See
[docs/self-update.md](docs/self-update.md) for the trust model.

### Podman version

podup tracks the **latest stable Podman** and supports its **last two majors —
Podman 5.x and 6.x**. It talks to Podman's native libpod API (still versioned
5.x — 5.2.0 on Podman 6), so it needs **Podman ≥ 5.0**. Validated on **Podman
5.x (5.8.1) and 6.0.0** (the latter in CI against Fedora rawhide). Many distributions still ship 4.x — check
`podman --version` and upgrade if needed. Fedora, Debian trixie/sid and recent
Ubuntu releases carry 5.x; on an older release, install or upgrade Podman
following the official guide: <https://podman.io/docs/installation>.

### Platforms

Linux, macOS and Windows (x86_64 and arm64). On macOS and Windows podup talks to
the `podman machine` VM through its host-side `unix://` socket or `npipe://`
named pipe; the socket must be local (remote `tcp://`/`ssh://` are rejected).

## 🚀 Quick start

```bash
podup up -d      # start the stack in the current directory
podup ps         # see what's running
podup down -v    # tear down and remove volumes
```

Rootless-native libpod API, real compose-spec (`extends`, profiles,
`develop.watch`, inline secrets), and systemd Quadlet export —
