MongoDB Enterprise Kubernetes Operator 0.4

Released 2018-10-04

  • If a backup was enabled in Ops Manager for a Replica Set or Sharded Cluster that the Kubernetes Operator created, then the Kubernetes Operator disables the backup before removing a resource.

  • Improved persistence support:

    • The data, journal and log directories are mounted to three mountpoints in one or three volumes depending upon the podSpec.persistence setting.

      Setting Mount Directories to
      podSpec.persistence.single One volume
      podSpec.persistence.multiple Three volumes

      Prior to this release, only the data directory was mounted to persistent storage.

    • A new parameter, labelSelector, allows you to specify the selector for volumes that Kubernetes Operator should consider mounting.

    • If StorageClass is not specified in the persistence configuration, then the default StorageClass for the cluster is used. In most of public cloud providers, this results in dynamic volume provisioning.

MongoDB Enterprise Kubernetes Operator 0.3

Released 2018-08-07

  • The Operator no longer creates the CustomResourceDefinition objects. The user needs to create them manually. Download and apply this new yaml file (crd.yaml) to create/configure these objects.

  • ClusterRoles are no longer required. How the Operator watches resources has changed. Until the last release, the Operator would watch for any resource on any namespace. With 0.3, the Operator watches for resources in the same namespace in which it was created. To support multiple namespaces, multiple Operators can be installed. This allows isolation of MongoDB deployments.

  • Permissions changes were made to how PersistentVolumes are mounted.

  • Added configuration to Operator to not create SecurityContexts for pods. This solves an issue with OpenShift which does not allow this setting when SecurityContextContraints are used.

    If you are using Helm, set managedSecurityContext to true. This tells the Operator to not create SecurityContext for pods, satisfying the OpenShift requirement.

  • The combination of projectName and orgId replaces projectId alone to configure the connection to Ops Manager. The project is created if it doesn’t exist.

Released 2018-08-03

  • Calculates WiredTiger memory cache.

MongoDB Enterprise Kubernetes Operator 0.1
