# 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. 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.

# App-specific deps. Python isn't required by claude-code itself
# (claude-code is a Node CLI), but is convenient for the agent to
# shell out to for ad-hoc scripts. Kept on its own layer so it can
# be moved to a downstream image if the base ever needs to shrink.

# 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
# (uid 1000) with a home directory, which is where claude-code will write
# its session state.

# Pre-create the skills directory so PRD 0002's host->container skill
# copier (bot_bottle/skills.py) drops files into a path owned by the

# baking it into the image avoids a permission-confusion footgun if a
# future change to the launcher copies in as a different user.

# to attach a TTY, but this CMD makes `docker run -it bot-bottle-claude` also
# do something useful for ad-hoc debugging.
