Public bug reported: 1. We are running: - RHEL 7.1 - OpenStack Kilo 2015-1 based on the Red Hat community edition RDO - OpenStack nova-docker driver (git tag: origin/stable/kilo) - Docker 1.6.1 (API version 1.18)
3. Reproduction is done when: Do follow this HowTO (http://bderzhavets.blogspot.de/2015/05/running-nova-docker-on-openstack-rdo.html) with a little deviation regarding the docker image selection: do take "docker.io/fedora:latest"! IMPORTANT: This docker image is built using a dockerfile not containing any "CMD" directive! Download the image from the docker hub: docker pull "docker.io/fedora:latest" Upload it to glance using: docker save "docker.io/fedora:latest" | glance image-create --name "docker.io/fedora:latest" --is-public true --container-format docker --disk-format raw Launch this docker image via the OpenStack Horizon dashboard. Please do not specify any commands in the post creation tab! Expected result: Docker image should start although the image misses a CMD directive using an alternative CMD like "bin/bash" or the nova-docker driver should detect this missing directive and prevent its startup. Alternatively, a more speaking error message should occur within the OpenStack "nova-compute.log". Actual result: The launch of the image aborts based on the docker API reply saying: "APIError: 500 Server Error: Internal Server Error ("No command specified")" 4.
