Description Clayton Coleman 2021-03-13 22:27:22 UTC
All payload components should request a reasonable minimum CPU and p90 memory usage


The openshift-marketplace batch job container "extract" does not request cpu or  memory.  Please follow recommendations in that doc.

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

Comment 1 Joe Lanford 2021-03-15 13:59:14 UTC
From the CONVENTIONS doc:

The memory request of cluster components should be set to a value 10% higher than their 90th percentile actual consumption over a standard end-to-end suite run.
The CPU request of cluster components is based on the following formula and lower/upper bound rules:

> floor(baseline_request / baseline_actual * component_actual)
> Then, these rules for lower and upper bounds should be applied:
>    The CPU request should never be lower than 5m. Setting a 5m limit avoids extreme ratio calculations when the node is stressed, while still representing the noise of a mostly idle workload.
>    If the computed value is more than 100m, use the lower of the computed value and 200% of the usage of the component in an idle cluster. This cap means components that require bursts of CPU time may be throttled on busy hosts, but they are more likely to be schedulable in the first place.

Since the openshift-marketplace's "extract" batch job is part of a control plane component, we will use etcd as a baseline to compute its CPU resource requests.

Both CPU and memory request formulas use numbers based on the end-to-end parallel conformance test job. After running the tests, use the Prometheus instance in the cluster to query the kube_pod_resource_request and kube_pod_resource_limit metrics and find numbers for the Pod(s) for the component being tuned.

Comment 3 Clayton Coleman 2021-03-25 22:16:33 UTC
Moving to high severity, payload workloads may not run without requests. 

This may not be deferred from 4.8

> This may not be deferred from 4.8

That means blocker+.

Comment 8 W. Trevor King 2021-04-16 02:55:58 UTC
pulling back to POST briefly while I update the test suite.  This will not affect verifying the marketplace fix, so feel free to go ahead with that.  Will be back to ON_QA shortly.

[scolange@scolange go]$ oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.8.0-0.nightly-2021-04-18-101412   True        False         26h     Cluster version is 4.8.0-0.nightly-2021-04-18-101412

1. Install an operator in a general namespaces

[scolange@scolange go]$ oc -n scolange get sub
NAME                             PACKAGE                          SOURCE                CHANNEL
couchbase-enterprise-certified   couchbase-enterprise-certified   certified-operators   stable
[scolange@scolange go]$ oc -n scolange get csv
NAME                        DISPLAY              VERSION   REPLACES                    PHASE
couchbase-operator.v2.1.0   Couchbase Operator   2.1.0     couchbase-operator.v2.0.2   Succeeded
[scolange@scolange go]$ oc -n scolange get ip
NAME            CSV                         APPROVAL    APPROVED
install-4vgjl   couchbase-operator.v2.1.0   Automatic   true

2. Verify the jobs from origin namespace in this case ( openshift-marketplace ) 

[scolange@scolange go]$ oc -n openshift-marketplace get jobs
NAME                                                              COMPLETIONS   DURATION   AGE

3. Verify inside the jobs the value of spec.containers[].resources.requests field are setted

scolange@scolange go]$ oc -n openshift-marketplace get jobs 5c410a08445875ef0dd1a81b992b068f3a86bd2f5a79c433ad9e0bc4d62ef09 -o yaml
