helm traefik does not watch all namespaces when rbac namespaced

[oleg-andreyev]

Welcome!

• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've searched similar issues on the Traefik community forum and didn't find any.

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

3.14.2

What version of Traefik are you using?

2.11.0

What did you do?

Following documentation and default Chart values, it is stated that traefik will watch all namespaces, but it's not

traefik-helm-chart/traefik/values.yaml

Lines 237 to 239 in ba5918d

	# -- Array of namespaces to watch. If left empty, Traefik watches all namespaces.
	namespaces: []
	# - "default"

If providers.kubernetesCRD.namespaces is not defined, helm will use default traefik namespace.
if providers.kubernetesCRD.namespaces is defined as. empty array, same result as above.

What did you see instead?

Looks like this configuration is conflicting with rbac.namespaced, probably it would be great to notify/warn user about it.

Thanks for your interest in Traefik.

Above rbac.namespaced, it says:

Providers will only watch target namespace

If you have an idea on how it can be improved, feel free to open a PR.

Since there is no news on this issue since 3 months, I close it.
Feel free to re-open it if needed.
