Add a Kubernetes cluster
Before you add a Kubernetes cluster in NetBackup, you must install and configure the Kubernetes operator in the cluster. Or else the validation of the cluster fails which further leads to fail the add cluster operation.
After Kubernetes operator configuration, you can add Kubernetes clusters in NetBackup and discover all the assets inside the cluster automatically.
To add a cluster
- On the left click Kubernetes, under Workloads.
- Click the Kubernetes clusters tab, click Add.
- In the Add Kubernetes cluster page, enter the following:
Cluster name: Enter a name for the cluster. The name should be a DNS resolvable value or an IP address. Example: cluster.sample.domain.com.
Port: Enter the Kubernetes API server port number.
Controller namespace: Enter the namespace where the NetBackup Kubernetes operator is deployed in the Kubernetes cluster. Example: kops-ns.
- Click Next. In the Manage credentials page, you can add credentials to the cluster.
To use an existing credential, choose Select from an existing credential, and click Next. In the next page, select the required credentials, and click Next.
To create a new credential, click Add credential, and click Next. In the Manage credentials page, enter the following:
Credential name: Enter a name of the credential.
Tag: Enter a tag to associate with the credential.
Description: Enter a description of the credential.
To add Kubernetes clusters in NetBackup you need a Certification Authority (CA) certificate and a token. CA certificate and a token of the backup service account is required for authorization and authentication of Kubernetes cluster. To get a CA certificate and token, run the following command in the Kubernetes cluster: kubectl get secret <[namespace-name]-backup-server-secret> -n <namespace name> -o yaml..
Token: Enter the authentication token value in Base64 encoded form.
CA certificate: Enter the CA certificate file contents.
- Click Next.
The credentials are validated and on successful validation, the cluster is added. After the cluster is added, autodiscovery runs to discover available assets in the cluster.
Note:
In NetBackup Kubernetes version 10.1, edit cluster operation fails with an error message. The recommended action to resolve this issue is to first delete the cluster and add the cluster again.
