4.6. Custom tuning example


The following CR applies custom node-level tuning for OpenShift Container Platform nodes with label tuned.openshift.io/ingress-node-label set to any value. As an administrator, use the following command to create a custom Tuned CR.

Custom tuning example

$ oc create -f- <<_EOF_
apiVersion: tuned.openshift.io/v1
kind: Tuned
metadata:
  name: ingress
  namespace: openshift-cluster-node-tuning-operator
spec:
  profile:
  - data: |
      [main]
      summary=A custom OpenShift ingress profile
      include=openshift-control-plane
      [sysctl]
      net.ipv4.ip_local_port_range="1024 65535"
      net.ipv4.tcp_tw_reuse=1
    name: openshift-ingress
  recommend:
  - match:
    - label: tuned.openshift.io/ingress-node-label
    priority: 10
    profile: openshift-ingress
_EOF_

重要

Custom profile writers are strongly encouraged to include the default Tuned daemon profiles shipped within the default Tuned CR. The example above uses the default openshift-control-plane profile to accomplish this.
