We’re pleased to announce the release of ClusterControl Ops-C v2.3.2, aligning with the ClusterControl (CCv2 UI) version released in April.

This release marks a significant milestone with the introduction of a technical preview for Kubernetes-native database management.

This version introduces support for deploying and managing databases in Kubernetes using community-driven database operators through declarative, YAML-based configurations with built-in version control, laying the foundation for cloud-native database operations with ClusterControl.

Kubernetes Database Operators with ClusterControl - Technical Preview

  • Supported Databases:

    • Easily deploy PostgreSQL and MySQL replication clusters to any Kubernetes environment.

  • Supported Database Operators

  • YAML-based management with version control

    • Manage deployment and backups with access to the YAML configurations, ensuring flexibility and control over the database operator setups.

  • Effortless scaling

    • Scale out or in by simply modifying the deployments

  • Backup management

    • Manage backup schedules
    • Restore the cluster from backups
    • Cloud object storage with S3 compliant cloud storage vendors

  • UI Integration

    • Leverage ClusterControl’s intuitive user interface to manage and monitor databases deployed in Kubernetes, streamlining operations regardless of database environments.

This is an early preview release of Kubernetes operator support and not meant for production use. In the meantime, we invite feedback from early adopters to help refine our roadmap and upcoming features.

ClusterControl Ops-C as the default application

Starting with this release, all new installations will default to ClusterControl Ops-C, which features Multi-CMON-Controller (scaling, multi-tenancy) and K8s databases capabilities

  • This is now the default for Users who download and install CC
  • The legacy LAMP stack with Apache is no longer included with the Ops-C stack. Apache has been replaced by the clustercontrol-proxy package, which provides similar web server functionality.
  • There is a parameter that can be used with the install-cc script '--ccv2,' which will then proceed to install the previous LAMP stack with CCv2 instead

By default, ClusterControl Ops-C does not have multiple-cmon-controllers (MCC) support enabled. It will need to be explicitly enabled by going to the Settings->License page (for now).

Initially, for all users, the UI will look and behave identically to ClusterControl GUI v2, except for the new Kubernetes page. The Kubernetes page can be hidden for Users who do not want to use it by going to Settings->License page and clicking on 'Disable Kubernetes'.
