Backing up ELMOperation instance by using Kubernetes CLI

The ELMOperation instance supports the backup of Engineering Lifecycle Management applications by using the Kubernetes CLI method.

1. Log in to your IBM Kubernetes Service cluster on IBM cloud and connect to your cluster namespace by using kubectl
2. Prepare the ELMOperation source manifest. Now, from the local computer create a yaml file called backup_elm_instance.yaml by using the following command.

   apiVersion: elm.ibm.com/v1
   kind: ELMOperation
   metadata:
     name: elmoperation-sample
     namespace: <namespace_name>
   spec:
     operationType: backupELMInstance
     allApplications: true
     backupLabel: latest
     selectedApplications:
       jas: false
       jts: false
       qm: false  
       dcc: false
       rm: false
       gc: false
       ccm: false
       eni: false
       ldx: false
       lqe: false
       rb: false

3. Run the following command:

   kubectl create -f backup_elm_instance.yaml -n <namespace_name>

   Replace the placeholders: For <namespace_name>, input the name of the project, where Engineering Lifecycle Management instance is created.

4. Verify the installation by using following command:

   kubectl get elmoperations elmoperation-sample -n <namespace_name>

   You can see the following output, when the ELMOperation is created successfully

   NAME                  AGE
   elmoperation-sample   2m27s

   The following message is displayed when the installation fails

   Error from server (NotFound): elmoperations.elm.ibm.com "elmoperation-sample" not found

   To help resolve this error, run the following command to check the ELMOperation name.

   kubectl get elmoperations -n <namespace_name>
   kubectl describe elmoperations elmoperation-sample -n <namespace_name>

   The output provides information about ELMOperation resources and status.

   Note: The exact path of the backup can be viewed from the logs section of the backup pod created.
