Managing Kubernetes Clusters

To meet the system requirements of applications running in Kubernetes clusters, you can have worker nodes with different numbers of CPUs and amounts of RAM. Creating workers with different flavors is possible by using worker groups.

When creating a Kubernetes cluster, you can specify the configuration of only one worker group, the default worker group. After the cluster is created, add as many worker groups as you need. If required, you can also edit the number of workers in a group later.

Limitations​
