How to reconfigure an AWS ParallelCluster instance after it started


How does one reconfigure values that were initially put to configuration YAML file that has been used to start an instance of AWS ParallelCluster?

In my case I simply want to remove the following snippets from partitions configuration as simply forgot to do that before starting the cluster:

Proxy:
  HttpProxyAddress: ....

I know that I can simply delete the cluster and create new one with corrected config. But I am really curious if there is a way to correct configuration of a running AWS ParallelCluster.


Solution

  • You can update a running cluster. You need to either stop your compute fleet or have a QueueUpdateStrategy set for the cluster. Check out the docs on this specific config parameter in the User Guide
