-------------------------------------------------- Description of problem: -------------------------------------------------- as a part of the new KubeVirt rate limiting testing, I tried to increase the number of virt-api pods using this which had no issues before, I suspect the new auto virt-api auto-scaler overwrites the manual patch. ================================================================================================ apiVersion: hco.kubevirt.io/v1beta1 kind: HyperConverged metadata: annotations: deployOVS: "false" hco.kubevirt.io/tuningPolicy: '{"qps":200,"burst":400}' kubevirt.kubevirt.io/jsonpatch: '[{"op": "add", "path": "/spec/customizeComponents/patches", "value": [{"resourceType": "Deployment", "resourceName": "virt-api", "type": "json", "patch": "[{\"op\": \"replace\", \"path\": \"/spec/replicas\", \"value\": 6}]"}]}]' ================================================================================================= oc get deployment virt-api -o yaml readyReplicas: 2 replicas: 2 updatedReplicas: 2 ================================================================================================= oc -n openshift-cnv get kubevirt kubevirt -o yaml customizeComponents: patches: - patch: '[{"op": "replace", "path": "/spec/replicas", "value": 6}]' resourceName: virt-api resourceType: Deployment type: json ================================================================================================= Boaz Ben Shabat, 10:29 AM [root@e29-h19-740xd storms_tool]# oc get pod -n openshift-cnv|grep virt-api virt-api-8795754c5-npd5m 1/1 Running 1 30h virt-api-8795754c5-v8tn5 1/1 Running 1 30h ================================================================================================= -------------------------------------------------- Version-Release number of selected component (if applicable): -------------------------------------------------- -------------------------------------------------- How reproducible: -------------------------------------------------- every time. -------------------------------------------------- Steps to Reproduce: -------------------------------------------------- apply the following patch: oc patch hco -n openshift-cnv kubevirt-hyperconverged --type=merge -p '{"metadata":{"annotations":{"kubevirt.kubevirt.io/jsonpatch":"[{\"op\": \"add\", \"path\": \"/spec/customizeComponents/patches\", \"value\": [{\"resourceType\": \"Deployment\", \"resourceName\": \"virt-api\", \"type\": \"json\", \"patch\": \"[{\\\"op\\\": \\\"replace\\\", \\\"path\\\": \\\"/spec/replicas\\\", \\\"value\\\": 6}]\"}]}]"}}}' -------------------------------------------------- Expected results: -------------------------------------------------- the number of virt-api pods should increase to 6
