# ============================================================
# Claude Code - Docker Swarm Stack (Option 1: Minimal)
# ============================================================
# Uses your Claude Pro/Max subscription via an OAuth token.
# No API key = no per-token charges.
#
# One-time setup (run on your host, NOT inside the container):
#   1. Install Claude Code locally:  npm install -g @anthropic-ai/claude-code
#   2. Generate a long-lived token:  claude setup-token
#      (opens browser, authorize with your claude.ai account)
#   3. Copy the printed token (starts with sk-ant-oat01-...)
#   4. Store it as a Docker secret:
#        echo -n "sk-ant-oat01-..." | docker secret create claude_oauth_token -
#   5. Deploy:
#        docker stack deploy -c claude-code-swarm-minimal.yml claude
