operator: remove invalid command flags like -loggerJSONFields

[mbrancato]

Is it possible for support for loggerJSONFields, as with other VM components, to be added to the operator? The operator seems to output in json by default, but the fields are not configurable from what I can tell.

I added this to the values.yaml for the Helm chart with no success using 0.44.0:

extraArgs:
  loggerFormat: json
  loggerJSONFields: "ts:timestamp,msg:message,level:severity"

Hi,
the extraArgs should work for each VM component. Can you see the -loggerJSONFields flag in pod's cmd after adding it to values.yaml?

I'm referring to the actual operator binary. It seems to output in JSON, but it doesn't support remapping fields. It lists it in the help, but I don't see the code to implement it and it definitely doesn't seem to work.

In other words, this image: https://hub.docker.com/r/victoriametrics/operator
or this release: https://github.com/VictoriaMetrics/operator/releases/tag/v0.44.0

I'm deploying with the helm chart and using extraArgs to pass the loggerJSONFields, resulting in a deployment with this:

  template:
    metadata:
      creationTimestamp: null
      labels:
        app.kubernetes.io/instance: victoria-metrics-operator
        app.kubernetes.io/name: victoria-metrics-operator
    spec:
      containers:
      - args:
        - --zap-log-level=info
        - --enable-leader-election
        - --loggerFormat=json
        - --loggerJSONFields=ts:timestamp,msg:message,level:severity
        command:
        - manager
        env:
        - name: WATCH_NAMESPACE
        - name: POD_NAME
          valueFrom:
            fieldRef:
              apiVersion: v1
              fieldPath: metadata.name
        - name: OPERATOR_NAME
          value: victoria-metrics-operator
        - name: VM_PSPAUTOCREATEENABLED
          value: "false"
        - name: VM_ENABLEDPROMETHEUSCONVERTEROWNERREFERENCES
          value: "false"
        image: victoriametrics/operator:v0.44.0

But the log fields are not remapped in the operator pod.

Okay, thanks for clarification.
Those flags are brought by github.com/VictoriaMetrics/VictoriaMetrics/lib/logger which we don't use directly inside operator, but used by other package like github.com/VictoriaMetrics/VictoriaMetrics/lib/promrelabel. Since we didn't Init the logger, those flags won't work.
And operator has it's own internal lib package github.com/VictoriaMetrics/operator/controllers/factory/logger, we need to do some cleanup about the flags.

Changes was included to v0.45.0 release.

Operator now longer exposes VM related flags.
