Current
DockerService
implementations capture docker process output streams (stdout
andstderr
) in the same thread one after the other.stderr
doesn't have to be very large before everything hangs indefinitely (process timeout limit will fail the process and clean it up eventually). This happens on arg configs that capture separate streams. If no output is captured it works because service redirects the streams to a single output stream.Now, when then is fixed...it will allow more log output since nothing hangs/crashes. We may need some "max docker capture size" restriction so we don't run out of memory holding onto output streams in variables returned to the process.
