# agent-canvas all-in-one entrypoint
#
# Starts three services (plus an optional fourth):
#   1. Agent Server   on port $AGENT_SERVER_PORT  (default 18000)
#   2. Automation     on port $AUTOMATION_PORT     (default 18001)
#   3. Static server  on port $PORT               (default 8000)
#      Routes /api/automation/* → automation, /api/* → agent-server,
#      and serves the frontend static build for everything else.
#   4. (Optional) Public-mode static server on $PUBLIC_MODE_PORT
#      Same frontend, but with --auth-required (no baked session key).
#      Used by auth-mode E2E tests. Only started when PUBLIC_MODE_PORT is set.
#
# Environment variables:
#   PORT                 – Unified entry point port (default: 8000)
#   AGENT_SERVER_PORT    – Internal agent-server port (default: 18000)
#   AUTOMATION_PORT      – Internal automation port (default: 18001)
#   AGENT_CANVAS_BASE_PATH – Static frontend mount path (default: /canvas)
#   VSCODE_PORT          – Internal editor port (default: 8001). The image does
#                          not EXPOSE it and the editor is reached through
#                          VSCODE_BASE_PATH on $PORT, but openvscode-server
#                          binds 0.0.0.0, so `docker run --network host` does
#                          leave it directly reachable with only its connection
#                          token in front of it.
#   VSCODE_BASE_PATH     – Path prefix the editor is served under on $PORT
#                          (default: /vscode). Exported to agent-server as
#                          OH_VSCODE_BASE_PATH and routed by the static server.
#                          agent-server's own OH_VSCODE_PORT / OH_VSCODE_BASE_PATH
#                          take precedence over these aliases; whichever is set,
#                          one effective pair drives both the editor process and
#                          the proxy route.
#   PUBLIC_MODE_PORT     – If set, starts a second static server on this port
#                          with --auth-required (no session key injected)
#   OH_SECRET_KEY        – Secret key for settings encryption (auto-generated
#                          and persisted if not provided)
#   OPENHANDS_AUTOMATION_API_KEY – Override automation backend auth key
#                          (defaults to session API key — both backends
#                          use the same `X-Session-API-Key` header)
#   AUTOMATION_AGENT_SERVER_URL  – URL the automation service uses to reach the
#                          agent-server (default: http://127.0.0.1:AGENT_SERVER_PORT).
#                          Setting this enables local-mode auth so the session
#                          API key is validated internally instead of against the
#                          OpenHands cloud API.
#   FILE_STORE             – Storage backend for automation tarballs (default: local).
#                          Without this the automation backend may fall back to
#                          S3/GCS which fails without cloud credentials.
#   LOCAL_STORAGE_PATH     – Directory for local file storage (default: ~/.openhands/storage)
#   AUTOMATION_BASE_URL    – Publicly-reachable base URL for the automation
#                          service, used in callback URLs and injected into
#                          sandboxes (default: http://127.0.0.1:$PORT).
#                          Override in production when the external URL differs.
#   AUTOMATION_WORKSPACE_BASE – Directory for automation run workspaces
#                          (default: ~/.openhands/workspaces)
#   Any agent-server or automation env vars are passed through.

# Keep the container alive while the static-server (ingress) is running.
# Backend crashes (agent-server, automation) are tolerated — the proxy
# returns 502 for downed routes, matching the non-Docker path where each
# service is an independent host process.
#
# Pattern: `sleep & wait $!` makes `wait` (a bash builtin) the foreground
# operation.  Unlike a bare `sleep`, the builtin `wait` is interrupted
# immediately when a trapped signal (SIGTERM/SIGINT) arrives, so cleanup()
# fires without delay.  cleanup() calls `exit 0` to terminate after the
# trap returns.  The loop re-checks the static-server PID every 10 s so the
# container exits promptly if the ingress process dies on its own.
