Compute Cloud (CC) – KaaS

CC also offers KaaS (Kubernetes as a Service). KaaS makes it easy to deploy and use a K8s cluster without having to worry about the underlying infrastructure.

Setup

  • Create a Cluster via Web Interface.
  • After successful creation, click „Get Cluster Config“.
    • Now the download of four files (cluster_config, cluster_ca.pem, cluster_cert.pem and cluster_key.pem) should start.
  • Add the following parameters to your config file:
    • certificate-authority-data: cat cluster_ca.pem | base64 | tr -d '\n'
    • client-certificate-data: cat cluster_cert.pem | base64 | tr -d '\n'
    • client-key-data: cat cluster_key.pem | base64 | tr -d '\n'
  • Your config file should now look like this: 
    apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0tLS0tCk1JS...
    server: https://172.17.x.y:6443
  name: playground
contexts:
- context:
    cluster: playground
    user: playground
  name: playground
current-context: playground
kind: Config
preferences: {}
users:
- name: playground
  user:
    client-certificate-data: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0tLS0tCk1JS...
    client-key-data: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0tLS0tCk1JS...
  • Now install kubectl to control the k8s cluster and put the config file in your home under .kube/conf.
  • The output of kubectl get nodes should now show your configured cluster.
