Update containerized PostgreSQL pod

The procedure describes the steps to update the image for NetBackup PostgreSQL pod in 11.0.

To update the containerized PostgreSQL pod for NetBackup version 11.0

Consider a scenario - In 11.0-xxxx deployment with netbackup-postgresql version 16.10.x.x, upgrade to netbackup-postgresql version 16.10.x.x using tag 11.0-patch2

  1. Suspend the backup job processing using the command:

    nbpemreq -suspend_scheduling

  2. Load, tag, and push the new NetBackup PostgreSQL image using the commands:

    To load the PostgreSQL imagedocker load -i VRTSnetbackup-postgresql-16.4.0002.tar.gz

    To load the PostgreSQL-upgrade imagesdocker load -i VRTSnetbackup-postgresql-upgrade-16.4-0002.tar.gz

    To tag the new imagesdocker tag netbackup/postgresql:16.4-0002 exampleacr.azurecr.io/netbackup/postgresql:11.0-patch2

    docker tag localhost/netbackup/postgresql-upgrade:16.4-0002 exampleacr.azurecr.io/netbackup/postgresql-upgrade:11.0_patch2

    To push the PostgreSQL imagedocker push exampleacr.azurecr.io/netbackup/postgresql:11.0-patch2

    docker push exampleacr.azurecr.io/netbackup/postgresql-upgrade:11.0-patch2

  3. Upgrade the PostgreSQL using Helm chart:

    To save PostgreSQL chart values to a file: helm show values postgresql-11.0-xx.tgz > postgres-values.yaml

    vi postgres-values.yaml

    Upgrade the PostgreSQL: helm upgrade --install postgresql postgresql-11.0-xx.tgz -f postgres-values.yaml -n netbackup

  4. Resume the backup job processing using the command:

    nbpemreq -resume_scheduling
