Dell ObjectScale Application 1.3.x Installation Guide for Red Hat OpenShift

Prepare the OpenShift cluster

In order to run kubectl and/or Helm commands from a Linux system against OpenShift cluster, obtain the kube config file from the OpenShift cluster.

1. On your Linux workstation, create the kube directory.

   mkdir -p ~/.kube

2. Using SCP copy the kubeconfig file from the service node to the Linux workstation. Command syntax is:

   scp root@<SERVICE_NODE_IP>:/root/ocp4/auth/kubeconfig ~/.kube/config

   You will need to provide the password for the service node to complete this step.

3. Edit the /etc/hosts to add the service node name to local hosts file.
   1. Locate the service node name in the config file

      grep server ~/.kube/config

      server: https://api.ocp4.myhost.com:6443

   2. Add the service node entry obtained above to the /etc/hosts file:

      <SERVICE_NODE_IP> <SERVICE_NODE_NAME> api.ocp4

      For example:

      10.55.66.100 api.ocp4.myhost.com api.ocp4

4. Verify accessibility to the service node by running this command on the Linux workstation:
   1. Get a list of all of the nodes in your cluster:

      kubectl get nodes

   2. Get a list of the Pods in the current namespace:

      kubectl get pods

   3. List deployments in the current namespace:
      NOTE: If ObjectScale has not yet been deployed to the cluster, there will be no ObjectScale related deployments listed in the default namespace.

      kubectl get deployments
