Maintenance Release: August 20th, 2025

  • Build:
    • clustercontrol-controller-2.3.3-14470
    • clustercontrol2-2.3.3-2095
    • clustercontrol-mcc-2.3.3-541

  • Controller:

    • Address an issue with SELinux on the CMON Controller node and Prometheus server setup (CLUS-5759).

    • Address an improvement to enable HTTPS only software repositories with a new configuration parameter 'force_https_repos' (CLUS-6194).

      • The force_https_repos cluster parameter automatically converts HTTP repository URLs to HTTPS during package repository setup operations, including EPEL and our repositories. When enabled, ClusterControl replaces any http:// URLs with https:// when configuring package repositories on database nodes.

      • Configuration steps:

        1. Access a cluster configuration.
        2. Set force_https_repos = true.
        3. Apply the configuration changes by restarting CMON.

        4. Quick check after CMON is restarted: 

          s9s cluster --list-config --cluster-id=<your_cluster_id> | grep force_https_repos`.
      Note

      This only affects future repository setup operations.

We’re pleased to announce the release of ClusterControl v2.3.3. This update introduces enhancements for elevated user privileges with Privileged Access Management integration of PowerBroker’s ‘pbrun’ as well as support for MongoDB 8.0 and MariaDB 11.8 LTS.

Features

PowerBroker’s pbrun Integration

A replacement for sudo, offering more flexibility and control.

  • Enhanced Security — Enables secure execution of privileged commands without exposing root credentials.
    • Granular privilege delegation — Users can be permitted to run specific commands only under controlled conditions.
    • Centralized policy enforcement — Access and permissions are defined by administrators in a central policy file, rather than on individual systems.
    • Audit trails and logging — All actions taken via pbrun are logged for accountability and compliance.
    • Role-based access control (RBAC) — Different users or roles can be given distinct levels of privilege.
    • Seamless Integration - Easily use pbrun within ClusterControl for consistent and secure database management workflows. This integration adds a layer of security and control for organizations with stringent privileged access requirements.

New Major Versions

These updates ensure compatibility with the newest features, performance improvements, and security enhancements offered by the respective database vendors.

  • Support for MongoDB 8.0 - MongoDB 8.0, released in October 2024, introduces significant enhancements across performance, security, scalability, and developer experience.
  • Support for MariaDB 11.8 - This is the latest Long-Term Support (LTS) version, now generally available. This release brings major improvements in performance, observability, and AI-readiness:
    • AI-Ready with Native Vector Search - Unlock the power of generative AI and semantic search:
    • New VECTOR data type to store ML embeddings directly in tables.
    • Vector indexing & distance functions (Cosine, Euclidean) for fast nearest-neighbor queries.
    • Ideal for RAG pipelines, personalized search, and recommendation engines—right inside your database.

Misc CC Ops-C / MCC UI improvements

  • Admin User Registration Form - 'Advanced Self-Serve' intent and new 'Feedback' input.
  • Improvements to multi-cmon controller registration and authentication process
