Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly MCC). This means everything you need is in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Addressed issues

The following issues have been addressed in the Mirantis Container Cloud release 2.6.0 and the Cluster release 5.13.0:

  • [11302] [LCM] Fixed the issue with inability to delete a Container Cloud project with attached MKE clusters that failed to be cleaned up properly.

  • [11967] [LCM] Added vrrp_script chk_myscript to the Keepalived configuration to prevent issues with VIP (Virtual IP) pointing to a node with broken Kubernetes API.

  • [10491] [LCM] Fixed the issue with kubelet being randomly stuck, for example, after a management cluster upgrade. The fix enables automatic restart of kubelet in case of failures.

  • [7782] [bootstrap] Renamed the SSH key used during bootstrap for every cloud provider from openstack_tmp to an accurate and clear ssh_key.

  • [11927] [StackLight] Fixed the issue with StackLight failing to integrate with an external proxy with authentication handled by a proxy server and ignoring the HTTP Authorization header for basic authentication passed by Prometheus Alertmanager.

  • [11001] [StackLight] Fixed the issue with Patroni pod failing to start and remaining in the CrashLoopBackOff status after the management cluster update.

  • [10829] [IAM] Fixed the issue with the Keycloak pods failing to start during a management cluster bootstrap with the Failed to update database exception in logs.

  • [11468] [BM] Fixed the issue with the persistent volumes (PVs) that are created using local volume provisioner (LVP) not being mounted on the dedicated disk labeled as local-volume and using the root volume instead.

  • [9875] [BM] Fixed the issue with the bootstrap.sh preflight script failing with a timeout waiting for BareMetalHost if KAAS_BM_FULL_PREFLIGHT was enabled.

  • [11633] [vSphere] Fixed the issue with the vSphere-based managed cluster projects failing to be cleaned up because of stale secret(s) related to the RHEL license object(s).
