If you have an installation of Ubuntu 16.04, you can install go &
docker, build docker from upstream source, copy all the docker binaries
(dockerd, docker, docker-containerd, docker-containerd-ctr, docker-
containerd-shim, and docker-runc) into  /usr/bin/ , and then run a
container (docker run -it ppc64le/ubuntu echo hi) and it will hang and
fail to exit.

====
Or, you can build docker in a container and then run  (the way the CI tests work):

0. Install docker
1. checkout and patch docker master:

diff --git a/Dockerfile.ppc64le b/Dockerfile.ppc64le
index 208c3a5..3fa36a0 100644
--- a/Dockerfile.ppc64le
+++ b/Dockerfile.ppc64le

2. build the docker dev container:
$docker build -t docker:1.6.1 -f Dockerfile.ppc64le .

3. Run the docker dev container
$docker run -it --privileged docker:1.6.1 /bin/bash

4. From the container, build the docker binary
root at 05f8c2e2a546:/go/src/github.com/docker/docker# ./hack/make.sh binary

5. Run a docker container:
root at 05f8c2e2a546:/go/src/github.com/docker/docker# cd bundles/latest/binary-daemon
root at 05f8c2e2a546:/go/src/github.com/docker/docker# ./docker &
root at 05f8c2e2a546:/go/src/github.com/docker/docker# cd ../docker-client
root at 05f8c2e2a546:/go/src/github.com/docker/docker# ./ ./docker run -it ppc64le/ubuntu echo hi
hi

You can see that the container runs, but never exits.

Is that helpful?

Title:
  Docker doesn't work since Containerd integration

Status in golang-1.6 package in Ubuntu:
  Fix Released

Bug description:
  -- Problem Description --
  Docker build hangs indefinitely when run using a 1.11.0 binary built after containerd integration, and go 1.6 on ppc64le. Doing the same thing works with gccgo.

  Looking at the differences in docker logs shows that the containerd
  event "exit", never happens when using a binary built with gc.
  fsnotify, the file system handler for go, doesn't seem to receive the
  correct event when a file is either written to, or closed, which I
  believe is whats causing this issue.

  Link to fsnotify issue which shows some failing tests :
  https://github.com/fsnotify/fsnotify/issues/130

  I have a patch that fixes the errors when I run fsnotify.  I am
  preparing it for submission now and should be out there as a golang CL
  this morning.

  Do you want the patch so you can rebuild golang with it?  If fsnotify
  is a separate package then you will have to rebuild it with the new
  golang.

  Here's the CL link if you want to get the patch for ppc64le:  https://go-review.googlesource.com/#/c/21582/
  Go to the upper right where it says download and I think if you select patch file it will give you the patch.

  We'll update with more info after testing the patch Lynn submitted,
  but we wanted to let Canonical know about this issue in the meantime
  since 1.11 is about to GA upstream.
