# Optional Linux Cloudflare Tunnel ingress, independent of OpenAI Secure MCP Tunnel.
# Usage (dedicated NEW deployment only): specify the intended Compose project,
# env file and complete overlay set before starting serverfs-mcp + cloudflared.
# For an existing production project, read docs/cloudflare-tunnel.md first;
# never run a generic up that could recreate existing ServerFS/Agent services.
# Create a remotely managed Cloudflare Tunnel and route its public hostname to
# http://serverfs-mcp:8000 (use the configured SERVERFS_HTTP_PORT if changed).
# Put the original Tunnel token in an operator-owned file OUTSIDE the checkout
# and all configured workdirs, mode 0600, owned/readable by CLOUDFLARED_UID.
# Set CLOUDFLARE_TUNNEL_TOKEN_FILE to that absolute path in the untracked .env.
# ServerFS HTTP authentication is configured separately (API Key or OAuth).

  # The base Compose keeps its historical OpenAI Tunnel default. Do not start
  # that separate control-plane client for the Cloudflare-only deployment.
