Image stopped working after adding copy to Dockerfile

Archive Rancher 1.x

I updated my Jenkins docker file to add rancher-compose to the container. When I’m upgrading the container to the new version i get the error below and the new container do not start. If i run the container locally on the command line it starts and i can use rancher-compose.

COPY rancher-compose/rancher-compose /usr/local/bin/rancher-compose
CMD service docker start

Any one have any idea what the problem is and have a solution?

Rancher 1.1.3
Docker 1.12.1

I found the answer. the problem was that the working Dockerfile by mistake did not run service docker start which should not be run in the firstplace. So two wrong became right:)
