= Recommended practices for installing large scale clusters
|
|
|
|
When installing large clusters or scaling the cluster to larger node counts,
|
|
set the cluster network `cidr` accordingly in your `install-config.yaml`
|
|
file before you install the cluster:
|
|
|
|
[source,yaml]
|
|
----
|
|
networking:
|
|
clusterNetwork:
|
|
- cidr: 10.128.0.0/14
|
|
hostPrefix: 23
|
|
machineCIDR: 10.0.0.0/16
|
|
networkType: OpenShiftSDN
|
|
serviceNetwork:
|
|
- 172.30.0.0/16
|
|
----
|
|
|
|
The default cluster network `cidr` `10.128.0.0/14` cannot be used if the cluster
|
|
size is more than 500 nodes. It must be set to `10.128.0.0/12` or
|
|
`10.128.0.0/10` to get to larger node counts beyond 500 nodes.
