= Network configuration parameters
|
|
|
|
You can modify your cluster network configuration parameters in the
|
|
`install-config.yaml` configuration file. The following table describes the
|
|
parameters.
|
|
|
|
[NOTE]
|
|
====
|
|
You cannot modify these parameters in the `install-config.yaml` file after installation.

|Parameter|Description|Value
|
|
|
|
|`networking.networkType`
|
|
|The default Container Network Interface (CNI) network provider plug-in to deploy.
|
|
ifdef::openshift-origin[]
|
|
|Either `OpenShiftSDN` or `OVNKubernetes`. The default value is `OVNKubernetes`.
|
|
endif::openshift-origin[]
|
|
ifndef::openshift-origin[]
|
|
|Either `OpenShiftSDN` or `OVNKubernetes`. The default value is `OpenShiftSDN`.
|
|
endif::openshift-origin[]
|
|
|
|
|`networking.clusterNetwork[].cidr`
|
|
|A block of IP addresses from which pod IP addresses are allocated. The
|
|
`OpenShiftSDN` network plug-in supports multiple cluster networks. The address
|
|
blocks for multiple cluster networks must not overlap. Select address pools
|
|
large enough to fit your anticipated workload.
|
|
|An IP address allocation in CIDR format. The default value is `10.128.0.0/14`.
|
|
|
|
|`networking.clusterNetwork[].hostPrefix`
|
|
|The subnet prefix length to assign to each individual node. For example, if
|
|
`hostPrefix` is set to `23`, then each node is assigned a `/23` subnet out of
|
|
the given `cidr`, allowing for 510 (2^(32 - 23) - 2) pod IP addresses.
|
|
|A subnet prefix. The default value is `23`.
|
|
|
|
|`networking.serviceNetwork[]`
|
|
|A block of IP addresses for services. `OpenShiftSDN` allows only one
|
|
`serviceNetwork` block. The address block must not overlap with any other
|
|
network block.
|
|
|An IP address allocation in CIDR format. The default value is `172.30.0.0/16`.
|
|
|
|
|`networking.machineNetwork[].cidr`
|
|
|A block of IP addresses assigned to nodes created by the {product-title}
|
|
installation program while installing the cluster. The address block must not
|
|
overlap with any other network block. Multiple CIDR ranges may be specified.
|
|
|An IP address allocation in CIDR format. The default value is `10.0.0.0/16`.
