Description
When running docker run --name static-site -e AUTHOR="Your Name" -d -P dockersamples/static-site, the container seems to start, and it returns the container id. However, docker port static-site does not return anything, and docker ps returns no rows (other than the header).

docker ps -a indicates the container started, and exited a few second later with exit code 1.
738cc5bf48f5 dockersamples/static-site "/bin/sh -c 'cd /usr…" 12 seconds ago Exited (1) 10 seconds ago static-site

docker info returns 0 running containers.

When trying to run the container again, it returns an error message that the container name is already in use by the container (and gives the container id of that container). When using sudo docker rm <id> it returns the container id. Issuing the command once more, returns that there is no such container (as expected).

Steps to reproduce the issue, if relevant:

1. Install Docker through the install script (Raspbian on Raspberry Pi 3)
2. (sudo) docker run --name static-site -e AUTHOR="Your Name" -d -P dockersamples/static-site
3. (sudo) docker ports static-site

Describe the results you received:
Nothing.

Describe the results you expected:

443/tcp -> 0.0.0.0:32772
80/tcp -> 0.0.0.0:32773

(or similar)

Additional information you deem important (e.g. issue happens only occasionally):
hello-world, ubuntu and alpine images ran fine.
