This section outlines new features and enhancements introduced in the Mirantis Container Cloud release 2.13.0. For the list of enhancements in the Cluster releases 7.3.0 and 5.20.0 that are supported by the Container Cloud release 2.13.0, see the Cluster releases (managed).

Configuration of multiple DHCP ranges for bare metal clusters

Implemented the possibility to configure multiple DHCP ranges using the bare metal Subnet resources to facilitate multi-rack and other types of distributed bare metal datacenter topologies. The dnsmasq DHCP server used for host provisioning in Container Cloud now supports working with multiple L2 segments through DHCP relay capable network routers.

To configure DHCP ranges for dnsmasq, create the Subnet objects tagged with the ipam/SVC-dhcp-range label while setting up subnets for a managed cluster using Container Cloud CLI.

Updated RAM requirements for management and regional clusters

To improve the Container Cloud performance and stability, increased RAM requirements for management and regional clusters from 16 to 24 GB for all supported cloud providers except bare metal, with the corresponding flavor changes for the AWS and Azure providers:

  • AWS: updated the instance type from c5d.2xlarge to c5d.4xlarge

  • Azure: updated the VM size from Standard_F8s_v2 to Standard_F16s_v2

For the Container Cloud managed clusters, requirements remain the same.
