NetBackup™ for Kubernetes Administrator's Guide

While fetching certificates if you get a message, EXIT STATUS 8500: Connection with the web service was not established. Then confirm from the nbcert logs whether hostname resolution successful or not. If it has failed, then perform the following steps:

Update the Kubernetes operator deployment.yaml and add the hostAliases in the deployment.

In the following hostAliases example,

hostAliases:
- hostnames:
  - backupserver.sample.domain.com
  ip: 10.20.12.13
- hostnames:
  -  mediaserver.sample.domain.com
  ip: 10.21.12.13

Copy, paste the hostAliases example details in the text editor and add to the hostAliases in the deployment.

Update configmap with backup server name.

Add datamover.hostaliases field, map with IP addresses to the hostname.

In the following configmap.yaml example,

apiVersion: v1

data:
  datamover.hostaliases: |
        10.20.12.13=backupserver.sample.domain.com
        10.21.12.13=mediaserver.sample.domain.com
  datamover.properties: |
        image=reg.domain.com/datamover/image:latest
  version: "1"
kind: configmap
metadata:
  name: backupserver.sample.domain.com
  namespace: kops-ns

To create the configmap.yaml file, run the command kubectl create -f configmap.yaml.

if you update the configmap.yaml which is already created then run the command to update configmap. kubectl apply -f configmap.yaml
