Deploy Kubernetes on a Single Master Node (without HA)

Single master mode does not have high availability.

  • Only set one node's k8s-role as master
  • Set this field load-balance-ip to your master's ip address

Kubernetes with High Availability: The `proxy` Role

There are 3 roles in k8s-role-definition. The master will start a k8s-master component on the specified machine. And the proxy will start a proxy component on the specified machine. In layout.yaml,

  • One or more than one nodes are labeled with k8s-role: master
  • One node should be labeled with k8s-role: proxy
  • Set the field load-balance-ip to your proxy node's ip address

Node: the proxy node itself is not in ha mode. How to configure the proxy node in ha mode is out of the scope of PAI deployment.

Kubernetes with High Availability: External Load Balancer

If your cluster has a reliable load-balance server (e.g. in a cloud environment such as Azure), you could set up a load-balancer and set the field load-balance-ip in the kubernetes-configuration.yaml to the load-balancer.

  • Set the field ```load-balance-ip`` to the ip-address of your load-balancer.
