问题
I'm planning a DR plan in case of zone failures in GCP.
Currently, Composer runs in a single zone. Is there a way to have its Kubernetes cluster regional?
回答1:
At the moment, no. The composer API requires a region when you create the environment but it chooses a single zone within that region to create the cluster. GKE can clearly support regional and multi-zonal clusters, so I recommend filing a feature request to add this functionality to composer
