@devlopergalxboy thanks for the PR! Could you please let us know what exact problem it solves? AFAICT it's already possible to install Zammad into namespaces via helm --namespace.

@mgruner when we tried to deploy using rendered manifest pattern we identified that most of our resources were not being injected with the correct namespace which left us out of sync on our ArgoCD as such we thought it would be a great idea that who ever wants to use zammad with the rendered manifest pattern they can do so without having issues of namespace injection.

Yes adding the flag --namespace to the command works well.

@monotek do you agree to this change?

That's exactly the reason I don't like ArgoCD.
I just won't work without changes to the resources it should just manage 🙄

FluxCD FTW! ;-)

But in the end the change does no harm.

Thank you @devlopergalxboy!
