Do not run containers in the background in the integration tests if you depend on the run completing. It is better especially if you just want to ensure that the run has completed with a `true` to just run in foreground and use a known name for the container to query it after it has stopped. The failures can be reproduced on most machines by giving your dind container one core and a cpushare. docker run -c 200 --cpuset 0 -ti --rm --privileged -e DOCKER_GRAPHDRIVER=vfs docker hack/make.sh binary test-integration-cli Signed-off-by: Michael Crosby <crosbymichael@gmail.com> Upstream-commit: ba5370c116e3879c88736d3456586ec5703f581b Component: engine
