# bot-bottle container image.
#
# Goal: a small, cache-friendly base that ships claude-code (the
# `@anthropic-ai/claude-code` npm package, CLI name `claude`) ready to run
# interactively. The container is ephemeral; per PRD 0001 v1 the host
# filesystem is not mounted in.
#
# Layer ordering is deliberate: the npm install lives in its own layer so
# changes to the rest of the repo (or to the CMD) don't bust it.

# Current Node LTS; slim variant keeps the image small while still
# providing apt-get for any future additions.
FROM node:22-slim

# Install runtime system deps. claude-code shells out to git for several
# features (status checks, commits, PR creation) — without git in the
# image, those features fail in surprising ways once the user does any
# real work. ca-certificates is already in the slim base; listed for
# clarity in case the base ever drops it. socat is the privileged
# forwarder for the in-container ssh-agent (see bot_bottle/ssh.py): the agent
# runs as root and rejects non-root connections, so socat sits between
# node and the agent socket. curl is here so any HTTPS_PROXY-aware
# tool (curl itself, plus anything that shells out to it) works
# against egress's bumped TLS without the agent needing local DNS.

# Install claude-code globally. Pinned to the version verified in the v1
# build (`claude --version` returns 2.1.126). Bump deliberately when
# rolling forward; an unpinned install would mean rebuilds silently pick
# up new behavior.

# Run as a non-root user. The node image already provides a `node` user

# its session state.

# do something useful for ad-hoc debugging.
