# opencode-devbox — variant image
#
# FROMs a base-<hash> image produced by Dockerfile.base and adds only
# the variant-specific tools (opencode, pi, oh-my-opencode-slim, Go).
#
# The two published variants are produced from THIS Dockerfile by
# varying build args:
#
#   variant   INSTALL_OPENCODE  INSTALL_OMOS
#   ────────  ────────────────  ────────────
#   base      true              false
#   omos      true              true
#
# pi was removed in v2.0.0 (it had been deprecated since v1.17.2). It now
# ships from its own self-contained image: joakimp/pi-devbox:latest
# (https://gitea.jordbo.se/joakimp/pi-devbox). See docs/CLEANUP-v2.0.0.md
# for the removal history.
#
# Pass `--build-arg BASE_IMAGE=<repo>:base-<hash>` to select the base.
# The CI workflow computes the base hash from Dockerfile.base + rootfs/
# + entrypoint*.sh and feeds it in.
#
# IMPORTANT: the base image sets NPM_CONFIG_PREFIX to
# /home/developer/.config/opencode/npm-global so runtime `npm install -g`
# by the developer user lands on the named volume. At BUILD time we want
# the baked binaries on /usr so they survive the volume mount. Each
# `npm install -g` below therefore prefixes the command with
# `NPM_CONFIG_PREFIX=/usr`.

# version was current when the cache was first populated. CI resolves it
