NebulaGraph Operator release notes

v1.8.0 (2024.02)

• Features:

  • Cluster Rolling Restart: Supported graceful rolling restart of all Pods in a certain type of service within the cluster or restart of a single Storage service Pod.
  • Local PV Failover: Combined the cloud's elastic scaling capabilities for computing resources to implement automatic failover. In case of a node failure, it automatically unbinds the Pod from the Local PV, allowing the Pod to migrate to other healthy nodes and continue running.

  • Backup and Restore:

    • Supported scheduled backups.
    • Supported backing up data to GCS.
    • Supported backup and restore of clusters with zones enabled.
    • Supported configuring policies for cleaning up expired backups.
    • Supported cross-namespace data backup.
  • Supported specifying the cluster through tags to manage the scope of clusters by the operator.

• Optimizations & Enhancements:

  • Optimized the retry mechanism of data balance type jobs to prevent the controller from getting stuck in the main process after a job failure.
  • Optimized uneven distribution of Pod scheduling across zones.
  • Added deletion protection mechanism for cluster deletion operations.
  • The mTLS feature can be disabled at any time after it is enabled.

  • Optimized Cluster Helm Chart:

    • Supported securityContext configuration, used to define permissions and access control for cluster containers.
    • Added console configuration, used to configure the nebula-console container image.
    • Supported enabling configuration and size configuration for service log storage.
    • Supported configuring multiple storage volumes for the Storage service.
    • Added alpineImage configuration, used to obtain the zone information where the node is located.
