Allow updating custom AMI for the Head Node #3292

Currently a cluster can't be updated to use a different custom_ami than it was created with. For deployments needing long installs of additional software, it is much more convenient to generate pre-baked images, given that the only workarounds are either deleting & recreating a cluster or deploying to the shared fs (which may not be accessible from the image's CI).

Hey there,

Thank you for the suggestion. We started to support compute custom AMI update with ParallelCluster 3. Head node custom AMI update is still not supported.

We would like to mark this as a feature request and take it into consideration.

Thank you! Hanwen
