Enable DB support via helm chart

[adamjk-dev]

As far as I can tell, there is no way to pass along extra env variables via env variables or a config map to load etc. into the container.

This would be the way to point to a different database correct?

Can the helm chart be updated to expose a way to set those env variables or read env variables from a named ConfigMap etc.?

Maybe a bit too much black (bash) magic, but anyone who ends up here might consider doing "helm template + yq + kubectl apply" instead of install.

To add the env vars with yq to the statefulset.yaml use something like this:

yq  -i '
  .spec.template.spec.containers[0].env += [
     {
        "name":  "UPTIME_KUMA_DB_TYPE",
        "value": "my-fancy-db"
     }, {
      "name": "UPTIME_KUMA_DB_HOSTNAME",
      "value": "here.there.svc.local"
     }
  ]  
' statefulSet.yaml
