Multi cluster configuration

Description

Currently I am working on multicluster Posit Workbench setup.
I will have main cluster where Workbench will be installed and where people will be able to run workloads and second cluster dedicated for GPU workloads.

When trying to configure that I followed this documentation which is mentioning that I need to have two [cluster] configured in my /etc/rstudio/launcher.conf file.

Issue

Problem start when I try to implement that configuration via helm chart since current implementation of cluster is map and when I provide more cluster it is merge and only last one if present in configuration file.

When I edited ConfigMap responsible for /etc/rstudio/launcher.conf and added second cluster like it was mention in doc it is working but since this is hacky way of doing this I would like to implement it in a proper way.

Do you have any recommendations how to do that?

Start with charts/rstudio-workbench/values.yaml at the cluster configuration and trace how it renders /etc/rstudio/launcher.conf. Compare the Helm output with the linked multi-cluster documentation; done means both cluster entries are preserved in the generated configuration without editing the ConfigMap manually.
