Managing Your Cluster

Once a cluster is created, the console provides information about its status and resources and allows you to configure it:

  • update/create node pools
  • update/create Kubernetes API whitelist rules
  • update/create VPN access
  • update/create AWS permissions

Note: Across the UI, a pencil icon indicates that you can modify an entity and a trashcan icon indicate that you can delete it from the console.

Viewing Load Balancers

When you define a Kubernetes service whose type is "LoadBalancer" Ridge creates a load balancer in the data center, external to the Cluster. The load balancer is automatically configured according to configuration defined in the cluster such as:

  • Ports and protocols
  • Health checks
  • White lists

You can view the cluster's load balancers on the Load Balancers tab of the cluster page. Ridge continually maintains, provisions, and monitors the load balancer throughout the life of the service.

Viewing Persistent Volumes

When you create a workload with a Persistent Volume Claim, Ridge creates a persistent volume, attaches the volume to the node and mounts the container to it. Ridge continually maintains, provisions, and monitors the PV throughout the life of the PVC.

You can see the persistent volumes created for the cluster on the Persistent Volumes tab of the cluster page.
