      resources:
        requests:
          memory: 
          cpu: 
        limits:
          memory: 
          cpu:

Testing

Check current resources:

1. deploy csi-operator from master branch

helm install csi-baremetal-operator http://asdrepo.isus.emc.com:8081/artifactory/atlantic-helm-build/csi-operator/${CSI_OPERATOR}/csi-baremetal-operator-${CSI_OPERATOR}.tgz --set image.tag=${CSI_OPERATOR} --set global.registry=asdrepo.isus.emc.com:9042 --set log.level=debug

2. deploy csi driver:

helm install csi-baremetal http://asdrepo.isus.emc.com:8081/artifactory/atlantic-helm-build/csi-operator/${CSI_OPERATOR}/csi-baremetal-deployment-${CSI_OPERATOR}.tgz --set image.tag=${CSI_VERSION} --set global.registry=asdrepo.isus.emc.com:9042 --set log.level=debug --set feature.extender=true  --set driver.drivemgr.type=halmgr  --set driver.alerts.mountConfig=true --set platform=vanilla

3. check csi containers resources:

$ kubectl get pod csi-baremetal-controller-64d9bd7bb5-mbv5x --output=yaml | grep -A 6 resources
    resources: {}
    ...
--
    resources: {}
    ...
--
    resources: {}
	...
--
    resources: {}
    ...
$ kubectl get pod csi-baremetal-node-controller-6d85489d95-gxck4 --output=yaml | grep -A 6 resources
    resources: {}
    ...
$ kubectl get pod csi-baremetal-node-kernel-5.4-2jbtm --output=yaml | grep -A 6 resources
    resources: {}
    ...
--
    resources: {}
    ...
--
    resources: {}
    ...
--
    resources: {}
    ...

4. upgrade csi-operator to version with CPU/memory values:

export CSI_OPERATOR=0.5.0-100.019c8f4
helm upgrade csi-baremetal-operator http://asdrepo.isus.emc.com:8081/artifactory/atlantic-helm-build/csi-operator/${CSI_OPERATOR}/csi-baremetal-operator-${CSI_OPERATOR}.tgz --set image.tag=${CSI_OPERATOR} --set global.registry=asdrepo.isus.emc.com:9042 --set log.level=debug

5. upgrade csi driver:

helm upgrade csi-baremetal http://asdrepo.isus.emc.com:8081/artifactory/atlantic-helm-build/csi-operator/${CSI_OPERATOR}/csi-baremetal-deployment-${CSI_OPERATOR}.tgz --set image.tag=${CSI_VERSION} --set global.registry=asdrepo.isus.emc.com:9042 --set log.level=debug --set feature.extender=true  --set driver.drivemgr.type=halmgr  --set driver.alerts.mountConfig=true --set platform=vanilla --set  driver.controller.resources.requests.memory=50Mi --set driver.node.resources.limits.cpu=200m

5. check csi containers resources:

anton@ubuntu:~/workspace$ kubectl get pod csi-baremetal-controller-776c84b68d-clpk6 --output=yaml | grep -A 6 resources
    resources:
      requests:
        memory: 50Mi
    ...
--
    resources: {}
    ...
--
    resources: {}
    ...
--
    resources: {}
    ...
$ kubectl get pod csi-baremetal-node-controller-6d85489d95-gxck4 --output=yaml | grep -A 6 resources
    resources: {}
    ...
$ kubectl get pod csi-baremetal-node-kernel-5.4-gmq4g --output=yaml | grep -A 6 resources
    resources: {}
    ...
--
    resources: {}
    ...
--
    resources:
      limits:
        cpu: 200m
      requests:
        cpu: 200m
    ...
--
    resources: {}

$ kubectl get pod csi-baremetal-se-tzjcf --output=yaml | grep -A 6 resources
    resources: {}
    ...

Could you add resources fields into Operator chart values too?

Since components specs changed we need to regenerate CRDs
