Description

When building the dockerfile, the build fails during the last EXPOSE stage. The following error is printed out:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"-p\": executable file not found in $PATH": unknown.
ERRO[0000] error waiting for container: context canceled

In order to fix this issue I specified the /tcp standard during the expose.

Fixes # (issue) Fixes Docker build failing.

Hey @nrweir , I am trying to figure out how to add the review needed label to get this reviewed. I can't seem to figure out how to update the label so that I can get this reviewed.
