Re: [Haskell-cafe] Static executables in minimal Docker containers

FWIW: I experienced something similar to this (hanging) with the standard Debian image. On Mon, Apr 13, 2015 at 3:16 PM Vo Minh Thu wrote:

I missed this thread but I guess I tried something similar last month: https://gist.github.com/noteed/4155ffad2b1d13ab17ee

I'm not sure if this issue would show up, but I can try it in Fedora tomorrow. I didn't address the linker warning at all right now, it seems to not have been triggered, though I suppose it is possible that it's the cause of this issue.

Haskell is not that great at producing statically linked libraries independent of the OS. The issue you are running into would likely show up in another

image (or even possibly a different version of an ubuntu image), so you could probably use a Fedora image that has tracing.

How are you addressing the linker warning about needing a particular glibc version at runtime?

Unfortunately, strace and ltrace aren't available in that Docker

image,

but it's a good idea to see if I can get them running there somehow.

Failing that, you might be able to get useful information of the same kind by running docker (the server, not the `docker run` command) under perf[0] and then running your busybox container. It should at least give you an idea of what it's doing when it explodes.
