Description Clayton Coleman 2021-03-13 17:34:38 UTC

All payload components should request a reasonable minimum CPU

https://github.com/openshift/enhancements/blob/master/CONVENTIONS.md#resources-and-limits

thanos-query container in thanos-querier does not.  I recommend assessing the p90 CPU use during an e2e run and using that value (something between 10m and 50m sounds "roughly correct").

Referenced from the new e2e test which gates components without resource requests and enforces the resource conventions.

Comment 2 hongyan li 2021-04-16 02:10:20 UTC

Test with payload 4.8.0-0.nightly-2021-04-15-152737

CPU request for container thanos-query is increased to 10m

oc -n openshift-monitoring get deployment.apps/thanos-querier -o go-template='{{range.spec.template.spec.containers}}{{"Container Name: "}}{{.name}}{{"\r\nresources: "}}{{.resources}}{{"\n"}}{{end}}'; echo -e "\n";
Container Name: thanos-query
resources: map[requests:map[cpu:10m memory:12Mi]]
