Cluster backup
Once NetBackup is up and running and the basic sanity test is done to ensure that the cluster is in a working state, then save the template of the cluster through CLI as follows:
Ensure that you are logged in through Azure CLI with subscription set to where the cluster is present:
az group export --resource-group <resource_group> --resource-ids <resourceID> --include-parameter-default-value
Or
az group export --resource-group <resource_group> --resource-ids /subscriptions/${subscription_id}/resourceGroups/$resource_group/providers/Microsoft.ContainerService/managedClusters/$cluster_name --include-parameter-default-value
Here,
Parameter
Description
resource_group
Resource group where the cluster is present.
resourceID
Cluster's resource ID. This can be obtained from the azure portal by navigating to the cluster and clicking on the JSON link present on the top corner of the Overview.
subscription_id
Subscription ID where cluster is present.
cluster_name
Cluster name that needs to be saved.
Copy the JSON output to a file and save it as a JSON file. For example,
template.jsonEnsure that
template.jsonfile is saved and is safe. This is required later to recover the cluster.Note the Azure Container Registry name which is attached to the cluster.
Note:
User must save the output of every command in different file.
Get the cluster details.
Use the following command to obtain the information of the cluster:
aws eks describe-cluster --name <cluster name>
Obtain the detailed information about each subnet which was received as output of the above command:
aws ec2 describe-subnets --subnet-ids <subnetID-1> <subnetID-2>
Obtain the IAM role name from describe-cluster command and using the following command save the policies attached to it:
aws iam list-attached-role-policies --role-name <role name>
Obtain the security group ID from describe-cluster command and using following command save the details of security-groups:
aws ec2 describe-security-groups --group-ids <Security group ID>
Get the nodegroup details.
Use the following command to get the list of all node groups:
aws eks list-nodegroups --cluster-name <cluster-name>
Obtain the information of a particular nodegroup from above list using the following command:
aws eks describe-nodegroup --nodegroup-name <nodegroup-name> --cluster-name <cluster-name>
User must execute this command for each node group in the cluster to obtain the details of each nodegroup.
Get the EFS ID details.
NetBackup uses two EFS IDs (Primary and Snapshot Manager server):
Get EFS ID of Primary server: spec > primary > storage > catalog > storageClassName
Get EFS ID of Snapshot Manager server: Get storage class name from spec > cpserver > storage > log > storageClassName.
Describe this storage class using the following command and note the fileSystemId:
kubectl describe sc storageClassName
Use following commands to describe EFS:
aws efs describe-file-systems --file-system-id <EFS ID>
Run the above EFS command for Primary and Snapshot Manager server EFS ID. The above EFS command does not describe the mount targets which was used while creating EFS. To get mount targets details use the following command:
aws efs describe-mount-targets --file-system-id <EFS ID>
Note the non-default parameters with which EFS was created.
Get the list of Add-on by using the following command:
aws eks list-addons --cluster-name <cluster-name>
