Upgrade the operator with the following command:
helm upgrade --namespace stackgres stackgres-operator \ --values my-operator-values.yml \ stackgres-charts/stackgres-operator
Important note: Do not use the
--reuse-valuesoption from Helm, this prevent the new operator resources and the new values needed to be set. Pass your installation params using the values file or setting the values directly in the command using
The main recommendation is to pass the same installation values in the upgrade command or using a values.yaml.
Upgrade of an operator can serve two purpose:
After the upgrade completes any new cluster that will be created, will be created with the new updated components. For existing clusters, there are two mechanisms in order to update components: in-place restart and reduced-impact restart. Both procedures are essentially the same but reduced-impact restart allow to restart a cluster with minimal throughput reduction for read-only connections (we will not apply draining here) or for read-write connections when a single node clusters is used.
