Additional examples (additionalContainers) about helm-charts HOT 8 CLOSED

I've just added a page to the documentation with an example, hopefully this explains things a bit?
https://bjw-s.github.io/helm-charts/docs/common-library/howto/helm-templates.html

from helm-charts.

Here's an example I use, anything passed into additionalContainers is a standard kubernetes containers object.

---
apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: bazarr
  namespace: default
spec:
# ...
  values:
# ...
    additionalContainers:
      subcleaner:
        name: subcleaner
        image: k8s.gcr.io/git-sync/git-sync:v3.6.2
        args:
          - --repo=https://github.com/KBlixt/subcleaner.git
          - --branch=master
          - --depth=1
          - --root=/add-ons/subcleaner
        volumeMounts:
          - name: add-ons
            mountPath: /add-ons
# ...

You services would still be defined in the Values of root object service.

Totally get it now. Spent a while looking for examples in your repos trying to figure it out, makes a lot more since seeing a working one.

In the values.yaml there is a mention that "Helm templates can be used". Is there an example of using a template there?

@putz612 do you mean in the context of additionalContainers? or something else?

from helm-charts.

Just in the context of additionalContainers. I have seen this comment on the library and did not understand what it meant. https://github.com/bjw-s/helm-charts/blob/main/charts/library/common/values.yaml#L195-L197

from helm-charts.

It does a lot, I was so very wrong with what that meant. Would it be possible to add the additionalContainers example with the note on the service as well? That one took me awhile to figure out. I really appreciate all the hard work that went into this. It's absolutely amazing. Thank you!

Once the Helm template is rendered the contents of additionalContainer gets added to the container list in the main Pod manifest which is defined by the Kubernetes PodSpec spec: https://kubernetes.io/docs/reference/kubernetes-api/workload-resources/pod-v1/#Container.

So if you would want to define ports, volumeMounts or set environment variables you would have to set them "as usual".
