I’m trying to change hypercube in the RKE1 cluster. I found (in https://rke.docs.rancher.com/example-yamls) that I can add system_images to the cluster configuration. Since that’s RKE1 I can’t edit yaml directly and I don’t see an option to change that via form.
What I tried is create a template and import a yaml where I put system_images under rancher_kubernetes_engine_config. But as far as I can see even if it imports the file, this change is never persisted so I guess there’s no field to deserialize this data into and it is ignored.
What is the right way to achieve that? Import full cluster.yaml from a file?
