Enable load balancing

​ ​If you're running Kubernetes in the cloud, you must configure an external load balancer for the Portworx API service on your source and destination clusters.​ An external load balancer is necessary because it assigns a public IP address for accessing Portworx on port 9001 from your worker nodes.

caution

It is recommended that you enable authorization on your Portworx cluster before enabling a load balancer.

​Enable load balancing by running the kubectl edit stc command and adding the annotation to change service type value from nodePort to LoadBalancer as shown below:

kubectl edit stc <stc-name> -n <namespace>

apiVersion: core.libopenstorage.org/v1
kind: StorageCluster
metadata:
  annotations:
    portworx.io/service-type: "portworx-service:LoadBalancer"
...
