There is a procedure to make the Dev Spaces Operator aware of the Openshift machine auto-scaler mechanism so it doesn't fail the DevWorkspace immediately when no resources are available in the cluster and waits until a new worker node joins the cluster. This configuration is discussed in https://issues.redhat.com/browse/CRW-4072 and its steps are documented in this kbase article https://access.redhat.com/solutions/7055312

However, it is not mentioned anywhere in the Admin Guide documentation. This is very important to have documented as it is a common need when running DevSpaces on ARO or ROSA.
