Crow CI

Backend: Local

Local backend configuration variables for agents.

BACKEND_LOCAL_TEMP_DIR

Section titled “BACKEND_LOCAL_TEMP_DIR”
  • Name: CROW_BACKEND_LOCAL_TEMP_DIR
  • Description: Directory in which pipelines are executed
  • Default: $TMPDIR

Each workflow gets its own directory below this one, and steps run with $TMPDIR pointing inside it rather than at the shared temp directory.

BACKEND_LOCAL_SANDBOX_LEVEL

Section titled “BACKEND_LOCAL_SANDBOX_LEVEL”
  • Name: CROW_BACKEND_LOCAL_SANDBOX_LEVEL
  • Description: Process isolation level on macOS, one of none, standard or strict
  • Default: standard

Implemented with the macOS sandbox-exec utility, and a no-op on Linux and Windows. See macOS Sandbox Security Levels for what each level allows.

BACKEND_LOCAL_USE_HOST_HOME

Section titled “BACKEND_LOCAL_USE_HOST_HOME”
  • Name: CROW_BACKEND_LOCAL_USE_HOST_HOME
  • Description: Run steps with the agent account’s own home instead of a per-workflow one
  • Default: false

Needed by tools that resolve the home directory from the account rather than from $HOME, such as Xcode reading provisioning profiles and writing DerivedData. Trades home isolation between workflows for compatibility with them.
