Managed Kubernetes¶
A GRN.CLOUD cluster is a Kubernetes cluster whose control plane GRN operates. GRN runs the API servers, etcd, the scheduler and the controller managers, applies upgrades, and maintains the storage, networking, observability and backup components installed in the cluster.
You hold cluster-admin and drive the cluster with standard oc, Helm and GitOps tooling.
There is no proprietary control surface in front of the Kubernetes API, so anything the
console does is an API call you can make yourself.
Three distributions are available: OKE (vanilla Kubernetes), OKD (open-source OpenShift) and OCP (Red Hat OpenShift). All three are CNCF-conformant, so manifests are portable between them and off the platform.
