leannetworking / k8s-netperf Goto Github PK

I am preparing a performance test on several 100Gb network interface cards with iperf3 and netperf on OpenShift 4.3 cluster with some servers.
Based on the YAML file I found on K8s-netperf Github repo, I followedthe YAML file to deploy K8s-netperf one by one including netperf-pod and netperf-host pods to OCP 4.3, but it shows errorr message for netperf-host (as DaemonSet) is not allowed to created due to the Nginx-Ingress SCC.
The following is the error message:

Error creating: pods "netperf-host-" is forbidden: unable to validate against any security context constraint: [provider nginx-ingress-scc: .spec.securityContext.hostNetwork: Invalid value: true: Host network is not allowed to be used spec.containers[0].securityContext.hostNetwork: Invalid value: true: Host network is not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 5001: Host ports are not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 8079: Host ports are not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 8080: Host ports are not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 8081: Host ports are not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 12865: Host ports are not allowed to be used provider restricted: .spec.securityContext.hostNetwork: Invalid value: true: Host network is not allowed to be used spec.containers[0].securityContext.hostNetwork: Invalid value: true: Host network is not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 5001: Host ports are not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 8079: Host ports are not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 8080: Host ports are not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 8081: Host ports are not allowed to be used spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 12865: Host ports are not allowed to be used]
