Managed your clusters with Kurator

Kurator cluster operator provide an easy way to get your Kubernetes cluster up and running.

• Think of it as operator for clusters
• Built on Cluster API and KubeSpray
• Manage your cluster plugins, such as CNI, CSI and Ingress controller

Concepts

• Kurator will provision all necessary resources (e.g. vpc, iam profile etc) for a Cluster;
• After Cluster API resources created, controllers imported from Custer API projects will provision the Kubernetes cluster;
• After cluster is provisioned, Kurator will install plugins for it;
• Once all plugins are properly installed, the cluster will be ready.

Architecture

The overall architecture of Kurator cluster operator is shown as below:

The Kurator Cluster Operator runs various controllers, which watch cluster api objects and then talk to the underlying clusters’ API servers to create Kubernetes clusters.

1. Cluster API controllers: imports from Cluster API projects and uses Kubernetes-style APIs and patterns to automate cluster lifecycle management for platform operators.
2. Kurator Cluster controller: watches Kurator Cluster API objects. When a Cluster object is added, the controller will provision target cluster.
