Cluster scaling

Cluster scaling

  • The design and architecture of OpenShift Container Platform place the following resource hosting limits on an OpenShift cluster:

    • Nodes per cluster: 2,000
    • Pods per cluster: 150,000
    • Pods per node: 250
    • Pods per core: Not specified; limited by maximum pods per node
    • Namespaces per cluster: 10,000
    • Number of builds: 10,000 (based on 512 MB RAM per image)
    • Pods per namespace: 25,000
    • Services per cluster: 10,000
    • Services per namespace: 5,000
    • Back ends per service: 5,000
    • Deployments per namespace: 2,000

    Red Hat offers support for OpenShift Container Platform 4.6 up to these limits, as described in Planning your environment according to object maximums.
