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.
