What version of the Traefik's Helm Chart are you using?

26.0.0

What version of Traefik are you using?

v3.0.0-rc1

What did you do?

we are trying to use OpenTelemetry tracing / metrics, but it looks like that the chart does not support this yes and is still using the old args for OpenTelemetry.

e.g. --tracing.openTelemetry=true vs --tracing.otlp.grpc=true

What did you see instead?

Treafik will not start when using the OpenTelemetry vaules.

What is your environment & configuration?

 tracing:
      openTelemetry:
        address: localhost:4318
        grpc: true

Hello @Links2004 ,

That's right. This chart supports stable version of Traefik. Considering the changes on tracing, I'm unsure if and how it can be implemented in this Chart to support both v2 and v3.

openTelemetry is only supported by v3 and the chart handles this here:
