# Codeman agent base image (built locally by scripts/build-agent-image.mjs).
#
# Contains the agent toolchain (node + the CLIs + git/tmux/ripgrep) but NO
# secrets: credentials are delivered at RUNTIME via bind mounts (~/.claude etc.)
# or name-only `docker exec --env`, never baked in, so `docker save` exports stay
# secret-free. tmux is a HARD prerequisite (the in-container tmux is what makes a
# reconnect durable), so it is installed here and probed before launch.
#
# HOME is made writable by an ARBITRARY host uid via the OpenShift "gid 0,
# group-writable" convention: on Linux we run `--user <hostUid>:0`, so the agent
# uid is the host uid (workspace files stay host-owned) while gid 0 keeps $HOME
# writable even though the uid is not the baked 1000.
FROM node:22-bookworm-slim

# Base toolchain. `curl` is needed for the hook callbacks (`curl -sk $CODEMAN_API_URL`),
# `procps` for `ps`, `tmux` for the durable in-container session.
