Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Remote storage for Tungsten Fabric database backups¶

MOSK enables you to store Tungsten Fabric database backups on a remote storage system. Using remote storage helps offload backups from the control plane nodes, improves data durability, and simplifies disaster recovery procedures. This section explains how to configure the supported remote storage options, including Network File System (NFS) storage and S3 object storage.

Remote NFS storage for Tungsten Fabric database backups¶

Available since MOSK 23.2 TechPreview

MOSK supports configuring a remote NFS storage for Tungsten Fabric data backups through the TFOperator custom resource:

API v2 Available since MOSK 24.1

spec:
  features:
     dbBackup:
       enabled: true
       backupType: "pv_nfs"
       nfsOptions:
         path: <PATH_TO_SHARE_FOLDER_ON_SERVER>
         server: <IP_ADDRESS/DNS_NAME_OF_SERVER>

API v1alpha1 Removed in MOSK 25.1

spec:
  controllers:
    tf-dbBackup:
      enabled: true
      backupType: "pv_nfs"
      nfsOptions:

        server: <IP_ADDRESS/DNS_NAME_OF_SERVER>

If PVC backups were used previously, the old PVC will not be utilized. You can delete it with the following command:

kubectl -n tf delete pvc <TF_DB_BACKUP_PVC>
