# opencode-devbox docker-compose for shared machines
#
# For machines where multiple users share one OS account (e.g. 'garage').
# Each user gets isolated config, data, and named volumes by setting
# SIGNUM in their .env file.
#
# Setup per user:
#   1. mkdir -p ~/<signum>/opencode-devbox && cd ~/<signum>/opencode-devbox
#   2. cp docker-compose.shared.yml docker-compose.yml
#   3. cp .env.shared.example .env
#   4. Edit .env with your signum, provider, keys, etc.
#   5. mkdir -p ~/<signum>/.config/opencode
#   6. docker compose up -d
#
# Named volumes are automatically isolated per user because Docker Compose
# prefixes them with the project directory name (e.g. opencode-devbox_devbox-data).
# Since each user runs from ~/<signum>/opencode-devbox/, volumes don't collide.
