IBM-MQ helm chart kubernetes can't see resource limits

11/9/2021

I'm trying to deploy IBM-MQ to Kubernetes (Rancher) using helmfile. I was getting the same error as here.

It wasn't working with storage class "longhorn", but was working with storage class "local-path". I added security: initVolumeAsRoot: true to my helmfile, now it looks like this:

....
  - name: ibm-mq
    ...
    chart: ibm-stable-charts/ibm-mqadvanced-server-dev
    values:
      - license: accept
        security:
          initVolumeAsRoot: true
        resources:
          limits:
            cpu: 800m
            memory: 800Mi
          requests:
            cpu: 500m
            memory: 512Mi
        image:
          tag: latest
        dataPVC:
          storageClassName: "longhorn"
          size: 500Mi
       ...

But in the Lens in the Stateful Sets I can see that it can't create a pod because of the error create Pod ibm-mq-0 in StatefulSet ibm-mq failed error: pods "ibm-mq-0" is forbidden: failed quota: default: must specify limits.cpu,limits.memory.

But the same helmfile without security worked fine, it didn't get an error because of limits, but got an error because there were problems with longhorn (as in the question I linked). If I change it to local-path (without security) it works fine, but the problem is that with local-path I need to delete manually volume after every restart, which is not what I want (for example, database works on longhorn without deleting volume after every restart). What's might be the problem here? I'm running it using helmfile -n namespace apply

UPD: I tried to place all the values in the order they're presented here, but it didn't work. I'm using helm 3, helmfile v.0.141.0, kubectl 1.22.2
