pi efd254f4e6 docs: rewrite DOCKER_HUB.md for v1.0.0 reality + auto-inject pi version
The Hub description still described the pre-v1.0.0 reality (tags follow
pi npm version, builds FROM joakimp/pi-devbox:base-pi-only, opencode-
devbox lineage as source of truth) — none of that has been true since
v1.0.0 decoupled. End users on Hub got a misleading story.

DOCKER_HUB.md changes:
- Versioning section rewritten: semver from v1.0.0, with a deprecation
  note for the pre-v1.0.0 v{pi_version}[letter] scheme.
- New 'Build pipeline' section briefly explains the two-phase
  base/variant content-addressed structure so users understand what
  base-<hash> and base-latest tags are for.
- New 'Document and image tooling' section (pandoc, graphviz,
  imagemagick) added since these are new in v1.0.0 and broadly useful.
- Tealdeer noted (vs the old Node tldr).
- Tmux 0-indexing called out (relevant for future :latest-studio
  variant).
- Removed all 'pi-only build' / 'FROM base-pi-only' / 'opencode-devbox
  bakes the pi version' framing — pi-devbox is now self-contained.
- New {{PI_VERSION}} placeholder in 4 locations so the Hub description
  always shows which pi is in :latest.

Workflow change:
- update-description step now substitutes {{PI_VERSION}} placeholders
  in DOCKER_HUB.md before sending to Hub. PI_VERSION comes from the
  resolve-versions output (same one baked into the image), so the page
  and image can never disagree. Sanity-check fails the step if any
  unsubstituted placeholder remains.

pi-devbox

A self-contained Docker container for the pi coding-agent — pi + companion repos + MemPalace + a curated set of dev tooling, ready to run.

Current :latest ships pi {{PI_VERSION}} (resolved at build time; see Versioning).

Image variants

Tag Architectures Size (compressed) What you get
joakimp/pi-devbox:latest amd64, arm64 ~1.1 GB Self-contained: base + pi {{PI_VERSION}} + companions
joakimp/pi-devbox:vX.Y.Z amd64, arm64 same Pinned semver release
joakimp/pi-devbox:base-latest amd64, arm64 ~1.0 GB Base layer alias (internal building block; pull :latest instead)
joakimp/pi-devbox:base-<hash> amd64, arm64 ~1.0 GB Content-addressed base; immutable. Stable parent for variant rebuilds.

Quick start

One-shot, no persistence:

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

For a fully-configured environment with persistent settings, MemPalace memory, neovim plugins, and shell history surviving container recreation, use docker-compose. You don't need to clone the repo — just grab two template files:

mkdir -p ~/pi-devbox && cd ~/pi-devbox
curl -O https://gitea.jordbo.se/joakimp/pi-devbox/raw/branch/main/docker-compose.yml
curl -fsSL https://gitea.jordbo.se/joakimp/pi-devbox/raw/branch/main/.env.example -o .env
# Edit .env — set WORKSPACE_PATH, an LLM API key (ANTHROPIC_API_KEY,
# OPENAI_API_KEY, GEMINI_API_KEY, or AWS_*), and your git identity.
docker compose run --rm devbox pi

What's inside

pi and companions

  • pi {{PI_VERSION}} (@earendil-works/pi-coding-agent) — installed at /usr/bin/pi
  • pi-toolkit — keybindings (mosh/tmux-friendly Shift+Enter, Ctrl+J, Alt+J newline bindings), AWS env loader, settings template
  • pi-extensions — 7 user-facing extensions: ext-toggle, mcp-loader, todo, ssh-controlmaster, notify, git-checkpoint, confirm-destructive
  • fork (pi-fork) and recall (pi-observational-memory) tools
  • mempalace bridge — MCP extension auto-symlinked so pi reads/writes the host-mounted palace

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

MemPalace (persistent agent memory)

  • MemPalace + MCP server — semantic search over conversation history, knowledge graph, diary; queryable via 29 mempalace_* tools inside pi
  • ChromaDB ONNX embedding model pre-warmed at build time (all-MiniLM-L6-v2)
  • Bind-mount your host's ~/.mempalace and the host-pi and container-pi share one brain

Document and image tooling

  • pandoc — universal Markdown↔HTML/Org/RST/etc. conversion. Useful well beyond pi: agent-driven doc exports, format conversion, etc.
  • graphviz (dot) — diagram rendering pipelines
  • imagemagick (magick) — image conversion / resizing

Modern CLI tooling

  • Editor: neovim (LazyVim defaults), tmux (configured for 0-indexed sessions)
  • Search/nav: ripgrep, fd, fzf, zoxide
  • Display: bat, eza, htop, tree
  • Data: jq, yq
  • Help: tldr (tealdeer — Rust port; run tldr --update once to populate cache)
  • Git: git-lfs, git-crypt, gitleaks (for pre-commit secret scanning)
  • Build: gcc, g++, make, patch
  • Misc: gosu, age, rsync, less

Language toolchains

  • Python: system Python 3 + uv (preferred) for fast Python package management. Run any Python REPL/notebook stack on demand without bloating the image:
    uv run --with ipython ipython
    uv run --with jupyterlab jupyter lab --no-browser --port 8888
    uv run --with marimo marimo edit
    
  • Node.js v22 + npm (used by pi itself)
  • Rustrustup-init is on PATH; install toolchains on demand
  • Go — opt-in via --build-arg INSTALL_GO=true if rebuilding from source

Cloud + secrets

  • AWS CLI v2 — for SSO + Bedrock auth (pi's preferred LLM provider for the maintainer's setup)
  • Gitea MCP server — for Gitea API access from inside pi
  • age, git-crypt — encryption tooling

SSH and networking

  • OpenSSH client with ControlMaster auto preconfigured on a writable socket path (/tmp/sshcm/). Mitigates ssh banner-exchange failures behind CGNAT-restricted residential ISPs (~4-flow caps).
  • A LAN-access helper that auto-configures ssh jump-via-host on VM-backed hosts (OrbStack / Docker Desktop on macOS) so the container can reach the host's directly-attached LAN peers (dssh <peer> alias; DEVBOX_LAN_ACCESS / HOST_SSH_USER).

Versioning

From v1.0.0 onward, pi-devbox uses semver:

  • Major — architectural changes. v1.0.0 is the first decoupled release, where pi-devbox got its own self-contained build chain (previously it was a thin re-brand of opencode-devbox's pi-only variant).
  • Minor — new image variants, significant base additions.
  • Patch — pi version bumps, smaller fixes.

The pi binary version inside any given release is shown in this description (currently {{PI_VERSION}} for :latest) and asserted by smoke tests to match what's documented — version drift is caught at CI time, not on user pull.

Pre-v1.0.0 history. Tags v0.74.0…v0.79.0 followed the pi npm version directly (v{pi_version}[letter]). Those images remain on Hub but are deprecated in favor of :latest / :v1.X.Y. The legacy :base-pi-only* tags were CI artifacts of the old opencode-devbox-based build pipeline; they will be removed in a future opencode-devbox v2.0.0.

Build pipeline

pi-devbox is built in two phases:

  1. Base (Dockerfile.base) → base-<hash> tag, content-addressed over Dockerfile.base + rootfs/ + entrypoint*.sh. Rebuilt only when those change.
  2. Variant (Dockerfile.variant) → :latest and :vX.Y.Z. FROMs the base, adds the pi install + companions.

base-latest is an alias of the most recent base.

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
devbox-ssh-local /home/developer/.ssh-local LAN-jump key (one-time host authorization survives recreate)

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.
