Enable dynamic IP allocation¶

Available since the 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 managed clusters.

Using this feature, you can effortlessly deploy a large managed 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 managed 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 managed clusters:

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

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