# pi-devbox — pi coding-agent container
#
# Builds on top of the opencode-devbox base image, which provides:
#   Debian trixie, Node.js, AWS CLI, mempalace + MCP server, gitea-mcp,
#   dev tools (neovim, tmux, bat, eza, fzf, zoxide, ripgrep, uv, rustup),
#   user setup (developer/gosu), entrypoints, chromadb prewarm.
#
# This image adds only pi itself and its companion repos.
#
# Build args:
#   BASE_IMAGE        — base image to build from (default: base-latest)
#   PI_VERSION        — pi npm version: "latest" or a pinned version e.g. "0.74.0"
#   PI_TOOLKIT_REF    — git ref for pi-toolkit (default: main)
#   PI_EXTENSIONS_REF — git ref for pi-extensions (default: main)

# Install pi and clone companion repos.
# NPM_CONFIG_PREFIX is overridden to /usr so the baked binary lands at the
# system prefix — same pattern as opencode-devbox's variant Dockerfile.
# At runtime, NPM_CONFIG_PREFIX is reset to /home/developer/.pi/npm-global
# (inherited from base ENV) so user-installed packages land on the named
# volume and survive container recreate.
