It would be nice to improve the documentation a bit, and mention that only one agent is needed per node and that this agent will collect the logs across namespaces.

As I have understood,you do not set any namespace for the secret/daemonset, which is fine with me.

But this way, I could install multiple agents (for each namespace).

So a better documentation about the best practice installation for multiple namespaces would be nice.

Ahh yes, thanks for catching that. I just made a note that we collect from all namespaces currently.

Yeah, we now set our agent up w/o namespaces. During our beta, we originally had it set up inside `kube-system` but 2 of our testers mentioned that the pod wouldn't install unless it was in `default`. So we moved it out of `kube-system` but we still weren't sure what caused the issue since it worked fine on our cluster. We were using Kubernetes v1.4 so it could've been an older version issue.

Actually, kube-system is the right namespace for things like this.

I don't know why it didn't work -- maybe they put the secret in the wrong namespace?

Yeah one of those mysteries of life. :/ One day we'll probably go back and try this on a few older versions to see if we can repro what happened. But yeah, it was right off the bat when we started our beta, 2 different people said they had to modify the yaml in order to get it to work (something we wanted to avoid altogether).
