NetBackup™ Deployment Guide for Kubernetes Clusters

Note the following

• It is recommended to back up all logs before upgrading from NetBackup versions prior to 10.5 (versions prior to the unified fluentbit based logging).

• It is recommended to copy and check the differences between the sample and the default fluentbit-values.yaml file.

• When upgrading from versions prior to 10.5 to NetBackup version 10.5 or later, the logs would be collected in the fluentbit collector from up to two days prior to the date of the upgrade.

  When upgrading from NetBackup 10.5 or later, the logs that exist in the fluentbit collector from the previous release will remain in the fluentbit collector and would continue to be cleaned up as per the configured fluentbit collector cleanup policy.

• Use the following command to save the fluentbit chart values to a file:

  helm show values fluentbit-<version>.tgz > fluentbit-values.yaml

• Use the following command to edit the chart values:

  vi fluentbit-values.yaml

  Following is an example for fluentbit-values.yaml file:

  global:
    environmentNamespace: "netbackup"
    containerRegistry: "<EKS Container Registry Name>"
    timezone: null
   
  fluentbit:
    image:
      name: "netbackup/fluentbit"
      tag: 10.5-0036
      pullPolicy: IfNotPresent
   
    volume:
      pvcStorage: "100Gi"
      storageClassName: nb-disk-premium
   
    metricsPort: 2020
   
    cleanup:
      image:
        name: "netbackup/fluentbit-log-cleanup"
        tag: 10.5-0036
   
      retentionDays: 7
      retentionCleanupTime: '04:00'
   
      # Frequency in minutes
      utilizationCleanupFrequency: 60
   
      # Storage % filled
      highWatermark: 90
      lowWatermark: 60
   
  # Collector node selector value
  collectorNodeSelector:
      node_selector_key: agentpool
      node_selector_value: nbupool
   
  # Toleraions Values (key=value:NoSchedule)
  tolerations:
    - key: agentpool
      value: nbupool
    - key: agentpool
      value: mediapool
    - key: agentpool
      value: primarypool
    - key: storage-pool
      value: storagepool
    - key: data-plane-pool
      value: dataplanepool

• Execute the following command to upgrade the fluentbit deployment:

  helm upgrade --install fluentbit fluentbit-<version>.tgz -f fluentbit-values.yaml -n netbackup

  Or

  If using the OCI container registry, use the following command:

  helm install --upgrade fluentbit oci://abcd.veritas.com:5000/helm-charts/fluentbit --version <version> -f fluentbit-values.yaml -n netbackup
