# pi-devbox

A Docker container with [pi coding-agent](https://github.com/earendil-works/pi) pre-installed, built on top of [opencode-devbox](https://hub.docker.com/r/joakimp/opencode-devbox)'s base image. Pi gets a fully-loaded development environment in one `docker run`.

## Image variants

| Tag | Size (compressed) | What you get |
|---|---|---|
| `joakimp/pi-devbox:latest` | ~700 MB | Pi + companion repos, on top of the opencode-devbox base |
| `joakimp/pi-devbox:vX.Y.Z` | same | Pinned pi version (tracks the [pi npm package version](https://www.npmjs.com/package/@earendil-works/pi-coding-agent)) |

Multi-arch: `linux/amd64`, `linux/arm64`.

## Quick start

```bash
docker run -it --rm \
  -v "$PWD":/workspace \
  -v "$HOME/.ssh":/home/developer/.ssh:ro \
  joakimp/pi-devbox:latest pi
```

For persistent state (settings, bash history, neovim plugins, mempalace data) and a full dev workflow, use docker-compose:

```bash
git clone https://gitea.jordbo.se/joakimp/pi-devbox
cd pi-devbox
cp .env.example .env  # edit WORKSPACE_PATH, GIT_USER_NAME, GIT_USER_EMAIL, etc
docker compose run --rm devbox
# inside the container:
pi
```

## What's inside

Inherited from [opencode-devbox base](https://hub.docker.com/r/joakimp/opencode-devbox):

- **Debian trixie** (latest stable)
- **Node.js** (LTS), **uv** (Python tooling), **rustup** (Rust on-demand)
- **AWS CLI v2** + AWS Bedrock-ready config
- **MemPalace** + MCP server — persistent agent memory across sessions, queryable via `mempalace_*` tools inside pi
- **Gitea MCP** server
- **Dev tools**: neovim (LazyVim defaults), tmux, bat, eza, fzf, zoxide, ripgrep, git-lfs, make
- **Shell**: bash with history tuning, prefix-search bindings, fzf/zoxide integration

Added by pi-devbox:

- **pi** ([`@earendil-works/pi-coding-agent`](https://www.npmjs.com/package/@earendil-works/pi-coding-agent)) — baked at `/usr/bin/pi`, version pinned at build time via the `PI_VERSION` build-arg
- **[pi-toolkit](https://gitea.jordbo.se/joakimp/pi-toolkit)** — keybindings (mosh/tmux-friendly Shift+Enter, Ctrl+J, Alt+J newline bindings), AWS env loader, settings template
- **[pi-extensions](https://gitea.jordbo.se/joakimp/pi-extensions)** — 7 user-facing extensions: `ext-toggle` (manage extensions interactively), `mcp-loader` (load MCP servers via settings.json), `todo`, `ssh-controlmaster`, `notify`, `git-checkpoint`, `confirm-destructive`
- **mempalace bridge** — MCP extension auto-symlinked from `/opt/mempalace-toolkit` so pi can read/write the same palace as opencode

The entrypoint deploys all of these on first container start. Re-running is idempotent and preserves user edits.

## Versioning

Tags follow the pi npm version: `v0.74.0`, `v0.75.0`, etc. `latest` always points at the most recent release. When pi cuts a new upstream version, this image is rebuilt and re-tagged to match.

For container-level rebuilds on the same pi version (security updates, base bumps, fixes) the tag gets a letter suffix: `v0.74.0b`, `v0.74.0c`, …

## Persistent state

User edits and pi-installed packages survive container recreation when you mount these named volumes. Use the included `docker-compose.yml` and they're set up automatically.

| Volume | Mount point | What it holds |
|---|---|---|
| `devbox-pi-config` | `/home/developer/.pi/` | pi settings, extension toggles, sessions, user-installed pi packages (`npm install -g`, `pi install npm:…`) |
| `devbox-shell-history` | `/home/developer/.cache/bash` | bash history |
| `devbox-zoxide` | `/home/developer/.local/share/zoxide` | zoxide directory jump database |
| `devbox-nvim-data` | `/home/developer/.local/share/nvim` | neovim plugin & Mason package state |
| `devbox-uv` | `/home/developer/.local/share/uv` | uv Python installs and tool cache |

Optional volumes for MemPalace (commented out by default — uncomment in `docker-compose.yml` to persist conversation memory across restarts):

| Volume | Mount point | What it holds |
|---|---|---|
| `devbox-palace` | `/home/developer/.mempalace` | palace data (drawers, knowledge graph, embeddings) |
| `devbox-chroma-cache` | `/home/developer/.cache/chroma` | ChromaDB embedding model cache (~80 MB, can be rebuilt) |

## User-installed pi packages

`NPM_CONFIG_PREFIX` is set inside the container to `/home/developer/.pi/npm-global`. Anything you `pi install npm:<pkg>` or `npm install -g` lands on the `devbox-pi-config` named volume — survives container recreation **and** image rebuilds. A user-installed `pi` wins over the baked one via `PATH` order, so you can pin a different pi version without rebuilding the image.
