Configuring DR Operator

Complete the following steps to install the DR operator on the source and the target DR cluster.

  1. Run the following command on the bastion node of each cluster.

    oc apply -f /YAML/DR/dro_deployment.yaml

  2. Wait till the command execution is complete.
  3. Run the following command on the bastion node to verify if the deployment is successful.

    oc -n infoscale-vtas get pods

    See the Status in the output similar to the following

    NAME                          READY   STATUS     RESTARTS    AGE 
dr-controller-manager-xxxx    1/1     Running    0           114m

    Status must change from ContainerCreating to Running.

  4. Run the following commands to configure Metallb.

    Note:

    Run these steps only if you want Metallb as the load balancer. If you choose any other load balancer, refer to its documentation for installation and configuration.

    oc -n infoscale-vtas expose deployment dr-controller-manager --name my-lb-service --type LoadBalancer --protocol TCP --port 14155 --target-port 14155

    Here, DR controller uses port 14155 internally to communicate across peer clusters. After a successful installation and configuration, you can verify by running the following command

  5. oc get svc my-lb-service

    An output similar to the following indicates that installation and configuration is successful

    NAME            TYPE         CLUSTER-IP    EXTERNAL-IP    PORT(S)         AGE
my-lb-service   LoadBalancer <IP address>  <IP address>   14155:14155/TCP 13h

    Run this command on both the clusters and verify if installation and configuration is successful. Verify whether EXTERNAL-IP is accessible from one cluster to the other cluster.
