Docker role presets

The container entrypoint supports role presets through ARTHEXIS_ROLE_PRESET.

• Supported values: terminal (default), control, satellite, watchtower (alias: constellation, for backward compatibility/convenience).
• NODE_ROLE still has priority. If NODE_ROLE is set explicitly, it overrides ARTHEXIS_ROLE_PRESET.
• Optional feature toggles (ENABLE_CELERY, ENABLE_LCD_SCREEN, ENABLE_RFID_SERVICE, ENABLE_CAMERA_SERVICE, and ENABLE_CONTROL) can be set directly to override preset defaults.
• Preset toggle defaults are derived from the effective role after applying any explicit NODE_ROLE override.

Examples

Run a Control node:

docker run --rm -p 8888:8888 \
  -e ARTHEXIS_ROLE_PRESET=control \
  arthexis:latest

Run a Satellite node:

docker run --rm -p 8888:8888 \
  -e ARTHEXIS_ROLE_PRESET=satellite \
  arthexis:latest

Override the role explicitly with NODE_ROLE:

docker run --rm -p 8888:8888 \
  -e ARTHEXIS_ROLE_PRESET=satellite \
  -e NODE_ROLE=Control \
  arthexis:latest
