Which chart:

stable/traefik

What happened:

When you change values in the values file and run:
helm upgrade traefik the values in etcd were not changed.

What you expected to happen:

If I run helm upgrade and afterwards:
kubectl run --rm -it traefik-etcd-test --image=quay.io/coreos/etcd:v3.1.8 --restart=Never --env="ETCDCTL_API=3" -l app=traefik -- etcdctl --endpoints=http://traefik-etcd-cluster-client:2379 get <traefik/dir/key> --prefix
I should see the new value.

How to reproduce it (as minimally and precisely as possible):

Install Traefik with HA enabled and ETCD as Key/Value Provider

Anything else we need to know:

I create a PR for this running the storeconfig job also after upgrades.

I need some changes in Traefik itself or support to move on with this issue/PR :-(

[bit-herder]

can we get some movement here? We have been waiting on HA forever and even tho there are instructions in the readme, they don't work as far as i can tell. As soon as I run an upgrade my old PVC gets deleted, and then traefik wont start, so I cant run anything. Is that whats happening to everyone else?

edit: im sorry, my confusion, please ignore.

[alwinmarkcf]

@bit-herder no the PVC is not the place where the state is saved but the key/value store. So its ok when the PVC got killed. You need a KV Provider.

This PR is just about updating the configs in the KV Store while doing an helm upgrade. But this is not working, as it would not delete keys. So I need traefik to use the config.toml and not store/import the configs to the KV Store. The only thing that should be stored in the KV Provider should be the acme certs. But those are not configs but state.

[bit-herder]

@alwinmarkcf I described my setup in another issue. https://github.com/helm/charts/issues/7774

I may just be missing something, but the KV store is up.
