You have two Cloud Composer environments (dev and prod) and a Git repo for DAG code. You want DAGs deployed automatically to Composer when a specific Git tag is pushed. What deployment workflow should you implement?

The correct approach leverages Cloud Build to automate DAG deployment. Cloud Composer environments automatically load DAGs placed in their designated Cloud Storage buckets. Therefore, the most straightforward and recommended method is to use Cloud Build to copy the DAG code from your Git repository to the development Composer environment's Cloud Storage bucket for testing. If tests are successful, Cloud Build then copies the same tested code to the production Composer environment's Cloud Storage bucket. The incorrect options involve using KubernetesPodOperator or GKE directly for DAG deployment, which is not how Composer manages DAGs. Composer abstracts away the underlying GKE cluster for DAG management, relying on the Cloud Storage bucket for DAG synchronization.
