Welcome to the May release of ClusterControl. This update includes support for Redis Cluster and scaling of ClusterControl in high-volume node or multi-tenant environments. ClusterControl Operations teams can now deploy ClusterControl within Kubernetes using a Helm chart and provision database clusters using a ClusterControl Terraform provider. Additionally, this version supports the latest major releases of MongoDB, and Debian.

Key Features

Support for Redis Cluster

A distributed implementation of the popular in-memory data store, Redis. It is designed to provide high availability and horizontal scalability by dividing the dataset into multiple partitions and distributing them across multiple nodes:

• Deploy & Import.
• System and database dashboards.
• Cluster topology view.
• Configuration files management.
• Backup and restore – local storage only and retention setting.
• Scaling
  • Add and remove primaries or replicas
• Limitations – These features will be addressed in an upcoming release:
  • Backup management
  • Cloud storage
  • Advanced settings – compression, encryption, verify backup
  • Minor upgrades
  • User access (ACL) management

ClusterControl Operations Center

Horizontal scaling of ClusterControl:

• Use multiple ClusterControl installations / CMON controllers to handle large-volume environments of 1000+ nodes.
• Provide multi-tenancy isolation where each tenant is assigned their own CMON Controller.
• Consolidate and manage multiple CMON controllers from a single point/web application.
• Aggregated status dashboard.
• Clusters, Nodes, and CMON Controllers.
• CMON-Proxy LDAP authentication.
• Limitations:
  • WEB SSH (disabled / non-functional with the current release)

Terraform Provider for ClusterControl –  Terraform Registry

• Use Infrastructure as Code (IaC) tools to provision ClusterControl resources such as database clusters, nodes, and load balancers.
• Integrate ClusterControl with your existing Terraform manifests and CI/CD pipeline environments..
• Use our Terraform Provider to seamlessly provide automatic database cluster provisioning on public and private clouds.
• Documentation – Terraform provider for ClusterControl

ClusterControl Helm Chart – ClusterControl helm-chart

• Install and use ClusterControl on Kubernetes.
• Public helm GitHub repository – https://github.com/severalnines/helm-charts/tree/main/charts/clustercontrol.
• ClusterControl helm chart published on clustercontrol 2024.4.4 · severalnines/clustercontrol.

New Major Versions support

• MongoDB 7

• Debian 12

Miscellaneous

• PITR with MSSQL Server ‘transaction log’ backups.
• MySQL binary log backups (and restore) to/from cloud storage:
  • A new backup method named ‘binlog’.
  • Separate backups of the MySQL binary logs.
• CC UI:
  • Misc UI/UX improvements

Known Limitations

• Major upgrades with TimescaleDB v13 and v14:
  • ‘copy’ and ‘link’ method is currently not working properly.
