Download a GCS object

Reads a gs:// object to a temp file and stores it in Kestra internal storage. Optionally validates the file integrity by recomputing its checksum locally and comparing it to the value stored in GCS.

Properties

Assets this task consumes as inputs or produces as outputs, for lineage tracking and the asset graph (Enterprise Edition). A flow declaring this property on a task is rejected in the open-source edition.

Possible Values
IGNOREFAILWARN

Asset failure behavior

Behavior applied to the task state when a declared asset fails to render, emit, or be persisted (e.g. a lock conflict): FAIL escalates it to FAILED, WARN (default) warns it if it would otherwise succeed, IGNORE leaves the state untouched.

enableAutobooleanstring

Whether to auto-register assets referenced dynamically at runtime that are not statically declared in inputs or outputs.

Validate the downloaded file against the GCS checksum

When true, the file is streamed through a CRC32C hasher (or MD5 if the object has no CRC32C) and compared to the checksum reported by Google Cloud Storage. If the values differ, the task fails and the temporary file is deleted. Used for end-to-end integrity, not for security/authentication.
