Helm chart ignoring config file or given key value

I am not sure if the issue is related to promtail (helm chart used) or to helm itself.

I want to update the default host value for loki chart to a local host used on kubernetes, so I tried with this:

helm upgrade --install --namespace loki promtail grafana/promtail --set client.url=http://loki:3100/loki/api/v1/push

And with a custom values.yaml like this:

helm upgrade --install --namespace loki promtail grafana/promtail -f promtail.yaml

But it still uses wrong default url:

level=warn ts=2021-10-08T11:51:59.782636939Z caller=client.go:344 component=client host=loki-gateway msg="error sending batch, will retry" status=-1 error="Post \"http://loki-gateway/loki/api/v1/push\": dial tcp: lookup loki-gateway on 10.43.0.10:53: no such host"

If I inspect the config.yaml its using it doesnt use the internal url I gave during the installation:

root@promtail-69hwg:/# cat /etc/promtail/promtail.yaml 
server:
  log_level: info
  http_listen_port: 3101

client:
  url: http://loki-gateway/loki/api/v1/push

Any ideas? or anything I am missing?

Thanks

I don't think client.url is a value in the helm chart, but rather one inside a config file that your application is using.

Try setting config.lokiAddress:

config:
  lokiAddress: http://loki-gateway/loki/api/v1/push

It gets templated into the config file I mentioned.
