There was a problem hiding this comment.
The main problem right now is that I can't get this line to work. I'm not sure how to fake a k8s API which doesn't send any log lines.

PR Description
As mentioned in #281, users get this warning with
loki.source.kubernetes:It looks like
reader.ReadString('\n')gets called afterstream.Close()has already been called.Me and @wildum were looking at this today, and we suspect that decoupling the lifetime of the string from the timeout context + moving
stream.Close()to the end oftail()could remove the warning message.The warning message seems to be a cosmetic problem. No logs would be lost, but it's confusing since users don't expect to see a warning for something that works as expected. Making the shutdown more graceful will make the component logs less confusing.

Notes to the Reviewer
I am not yet sure how to test this. When we test it, I'll take the PR out of the draft stage.
