This container accepts arbitrary subcommands for gsutil. Execution flow of the container is as follows:

1. Checks if an environment variable DOWNLOAD_DIR is declared and the directory doesn't exist, then create the directory.
2. If the environment variable SOURCE_PATH is declared and not empty, then run gsutil cp ${SOURCE_PATH} ${DOWNLOAD_DIR}; otherwise pass all arguments to the gsutil command. This process is provided for backward compatibility and will be deprecated in the near future.
3. Run crond in the foreground.

For example, if you want to run gsutil mv gs://example/foo/bar gs://example/foo/buzz, run as follows:

$ docker run tkrs/gsutil-crontab mv gs://example/foo/bar gs://example/foo/buzz

If you want to run this container in a Kubernetes' Pod, give the instructions via the Pod's definition:
