Use the Kubernetes Bridge Settings page to set the IP block or the network CIDR ranges for your Kubernetes clusters and services. These settings affect only Kubernetes OVA and appliance-type deployments that use the Infoblox image.

The settings on the Kubernetes Bridge Settings page are also available on the device’s UI; for more information, see Troubleshooting On-Prem NIOS-X servers. If you want to reconnect a Kubernetes-based NIOS-X server that has already been disconnected AND you also want to change the Kubernetes CIDR settings, you must first reset the NIOS-X server before making the CIDR changes and reconnecting the NIOS-X server.

To configure a Kubernetes Bridge, specify the following:

  • Cluster CIDR: Select one of the following to define the IP block for your Kubernetes cluster:

    • Use default: 10.42.0.0/16: Select this to use the displayed CIDR for your Kubernetes clusters.

    • Use custom: Select this and then enter a valid CIDR for your Kubernetes cluster. Ensure that you have set the netmask to a network no larger than /24 and that you have enough IP addresses for the pods in the cluster.

  • Service CIDR: A service enables network access to a set of pods in Kubernetes. Select one of the following:

    • Use default: 10.43.0.0/16: Select this to use the displayed CIDR for your Kubernetes services.

    • Use custom: Select this and then enter a valid CIDR for your Kubernetes service. Ensure that you have set the netmask to a network no larger than /24 and that you have enough IP addresses for the services.
