I've also noticed that even if or some arbitrarily low number is specified, it tries to read the whole logfile into memory. If it's a big file it can crash the worker node.
Do you mean the docker implementation? If I read their code correctly, docker read the whole log before tail into memory once tail is specified, which may cause problem if tail is a very large number. So in our own implementation, I've avoided that. ;) However, where do you see the ?
Tail should be *int in the API, is it not?

Agree tail=0 no logs is intended behavior On Oct 21, 2016, at 6:01 PM, Lantao Liu wrote: How docker logs works: docker logs --tail=-1 CONTAINERID: prints all lines. docker logs --tail=1 CONTAINERID: prints the last line. docker logs --tail=0 CONTAINERID: prints no lines.

Yeah, tail is . But if , kubelet will see .
I think the linked to is the problem.
The obvious workaround is to instead use: kubectl logs --tail=1
/sig cli
The line pasted by chao implies omitempty should not be false for tail.
I hate to bump, but 'bump'. Still an issue here. Can confirm works but does not.
