5.3.8. Configuring a three-node cluster

You can optionally install and run three-node clusters in OpenShift Container Platform with no workers. This provides smaller, more resource efficient clusters for cluster administrators and developers to use for development, production, and testing.

Procedure

  • Edit the install-config.yaml file to set the number of compute replicas, which are also known as worker replicas, to 0, as shown in the following compute stanza: 

    compute:
- name: worker
  platform: {}
  replicas: 0
