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 Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Enable dynamic IP allocation¶

Available since MCC 2.26.0 (Cluster release 16.1.0)

This section instructs you on how to enable dynamic IP allocation feature to increase the amount of baremetal hosts to be provisioned in parallel on MOSK clusters.

Using this feature, you can effortlessly deploy a large MOSK cluster by provisioning up to 100 hosts simultaneously. In addition to dynamic IP allocation, this feature disables the ping check in the DHCP server. Therefore, if you plan to deploy large MOSK clusters, enable this feature during the management cluster bootstrap.

Caution

Before using this feature, familiarize yourself with DHCP range requirements for PXE.

To enable dynamic IP allocation for large MOSK clusters:

In the Cluster object of the management cluster, modify the configuration of baremetal-operator by setting dynamic_bootp to true:

spec:
  ...
  providerSpec:
    value:
      kaas:
        ...
        regional:
          - helmReleases:
            - name: baremetal-operator
              values:
                dnsmasq:
                  dynamic_bootp: true
            provider: baremetal
          ...
