There was a problem hiding this comment. Certificates for the Kubernetes cluster should be sourced from Secrets which could then be managed by cert-manager. This will keep the user in control of secrets rather than having them only available within the servers (and therefor difficult to get access to from a Crossplane composition). Crossplane compositions would also benefit from this K8s managed certificate for managing helm installs within the created cluster. |

This may work but composition is designed to work with MRs. So I'd suggest using
Objectfrom provider-kubernetes. Though that'd force you to have the whole secret YAML as raw template inCombineFromCompositepatch sinceObjectaccepts raw YAML.
