Description Cesar Wong 2020-04-16 20:50:19 UTC

Description of problem:
When using Calico SDN, the kube-proxy daemonset is deployed. It makes no cpu or memory rquests, resulting in pods with a QoSClass of BestEffort. A cluster with this configuration always fail this e2e test: https://github.com/openshift/origin/blob/4d0922fb92f85f566cb22bbaaedf587e8a50aca4/test/extended/operators/qos.go#L20

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Run e2e against a cluster running with Calico SDN

Actual results:
Test fails:
[sig-arch] Managed cluster should ensure control plane pods do not run in best-effort QoS

Expected results:
Test succeeds

hi, Cesar, could you help or which QE from Calico can help verified Calico related bug?

Comment 4 Cesar Wong 2020-04-29 21:21:15 UTC

There are instructions here: 
https://docs.projectcalico.org/getting-started/openshift/installation

I verified with 4.5.0-0.nightly-2020-04-29-173148:

$ oc get pods -n kube-proxy
NAME                         READY   STATUS    RESTARTS   AGE
openshift-kube-proxy-89h2b   1/1     Running   0          9m17s
openshift-kube-proxy-frpzw   1/1     Running   0          9m17s
openshift-kube-proxy-lbskh   1/1     Running   0          9m17s

Then look at the qosClass in the status of one of the pods:
$ oc get pod openshift-kube-proxy-89h2b -o jsonpath='{ .status.qosClass }' -n openshift-kube-proxy
Burstable

which means the bug is fixed. It was previously BestEffort, which was causing the e2e failure.

Comment 5 zhaozhanqi 2020-04-30 02:02:59 UTC

Comment 6 Richard Theis 2020-05-29 18:58:17 UTC
