This section outlines new features and enhancements introduced in the Mirantis Container Cloud release 2.10.0. For the list of enhancements in the Cluster releases 7.0.0, 5.17.0, and 6.16.0 that are supported by the Container Cloud release 2.10.0, see the Cluster releases (managed).
7.x Cluster release series with updated versions of MCR, MKE, and Kubernetes
Removal of IAM and Keycloak IPs configuration for the vSphere provider
Support of MKE 3.3.x series and 3.4.0 for cluster attachment
7.x Cluster release series with updated versions of MCR, MKE, and Kubernetes¶
Implemented the 7.x Cluster release series that contains updated versions of:
Mirantis Container Runtime (MCR) 20.10.5
Mirantis Kubernetes Engine (MKE) 3.4.0
Support of MKE 3.3.x series and 3.4.0 for cluster attachment¶
Added support of several Mirantis Kubernetes Engine (MKE) versions of the 3.3.x series and 3.4.0 for attaching or detaching of existing MKE 3.3.3 - 3.3.6 and 3.4.0 clusters as well as updating them to the latest supported version.
This feature allows for visualization of all your MKE clusters details on one management cluster including clusters health, capacity, and usage.
Initial CentOS support for the VMware vSphere provider¶
Introduced the initial Technology Preview support of the CentOS 7.9 operating system for the vSphere-based management, regional, and managed clusters.
Deployment of a Container Cloud cluster that is based on both RHEL and CentOS operating systems is not supported.
To deploy a vSphere-based managed cluster on CentOS with custom or additional mirrors configured in the VM template, the
squid-proxyconfiguration on the management or regional cluster is required. It is done automatically if you use the Container Cloud script for the VM template creation.
RHEL 7.9 support for the VMware vSphere provider¶
Added support of RHEL 7.9 for the vSphere provider. This operating system is now installed by default on any type of the vSphere-based Container Cloud clusters.
RHEL 7.8 deployment is still possible with allowed access to the
rhel-7-server-rpms repository provided by the Red Hat Enterprise
Linux Server 7 x86_64.
Verify that your RHEL license or activation key meets this requirement.
Guided tour in the Container Cloud web UI¶
Implemented the guided tour in the Container Cloud web UI to help you get oriented with the multi-cluster multi-cloud Container Cloud platform. This brief guided tour will step you through the key features of Container Cloud that can be performed using the Container Cloud web UI.
Removal of IAM and Keycloak IPs configuration for the vSphere provider¶
Removed the following Keycloak and IAM services variables that were used during a vSphere-based management cluster bootstrap for the MetalLB configuration:
Now, these IPs are automatically generated in the MetalLB range for certificates creation.
Command for creation of Keycloak users¶
Implemented the container-cloud bootstrap user add command that allows creating Keycloak users with specific permissions to access the Container Cloud web UI and manage the Container Cloud clusters.
For security reasons, removed the default
password password for Keycloak
that was generated during a management cluster bootstrap to access
the Container Cloud web UI.
Documentation enhancements for IAM¶
On top of continuous improvements delivered to the existing Container Cloud guides, added documentation about the Container Cloud user roles management through the Keycloak Admin Console. The section outlines the IAM roles and scopes structure in Container Cloud as well as role assignment to users using the Keycloak Admin Console.
