How it works

If you throw a message to a PubSub topic as follows, it will create a container instance in the Compute Engine and execute the command passed in the message content. The created instance will be automatically deleted after the command is completed.

Automatic termination of container instances base on this cool post.

$ gcloud pubsub topics publish create-batch-instance-topic --message="gcloud --help" --attribute=image_name="gcr.io/google.com/cloudsdktool/cloud-sdk:latest"
