How to set up a MySQL collector plugin for Netdata hosted on Kubernetes?

Question

I recently deployed Netdata on Kubernetes. And I wanted to use Netdata to record the status of Managed MySQL hosted in Linode.
I read the documentation and it said that I could set up a plugin called MySQL Collector. However, the documentation only mentioned how to edit the configuration file directly, not how to configure it for Kubernetes.
It says to edit /etc/netdata/go.d/mysql.conf, but it is in the container. Perhaps you can do it temporarily by editing it from the shell inside the container, but I don't think that's official.
How can I set up a MySQL collector in Netdata on Kubernetes?

I tried creating a folder /etc/netdata/go.d on the Kubernetes node computer anyway just to be sure and created the file there, but still could not do it. I have that folder group in the container, so I think I should be able to set it up there. But if I edit it directly, I think it will be reset after reboot.
So I came up with a way to set up one volume of /etc/netdata in Kubernetes, but I am not sure if this is a good decision. So I am not doing this because it seems dangerous.

That said, I would like to know how to officially set up a MySQL collector plugin to Netdata on Kubernetes.

I think you need to pass the config into the helm chart via whatever values.yaml you are using.

Here are some of the defaults for example.

So i think in your case:

    go.d:
      enabled: true
      path: /etc/netdata/go.d.conf
      data: |
        modules:
          pulsar: no
          prometheus: yes
          mysql: yes

    mysql:
      enabled: true
      path: /etc/netdata/go.d/mysql.conf
      data: |
        update_every: 1
        autodetection_retry: 0
        jobs:
          - name: some_name1
          - name: some_name1

something like above to pass in the relevant config files (as per docs you read) into k8s via the Netdata helmchart.
