Docker – How to run latest docker and docker-compose development versions

dockerubuntu-14.10

I'm trying to figure out how to run development builds of docker and docker-compose together on Ubuntu 14.10 to hopefully address a bug: https://github.com/docker/compose/pull/1349

Latest Docker development version

docker -v
# Docker version 1.7.0-dev, build 6a7a757

# docker-compose -v
docker-compose version: 1.3.0rc3
CPython version: 2.7.8
OpenSSL version: OpenSSL 1.0.1f 6 Jan 2014

But docker doesn't like the server version

# which docker 
/usr/bin/docker
# sudo /usr/bin/docker -d &

# docker ps
Error response from daemon: client and server don't have same version (client : 1.20, server: 1.15)

And the current development release candidate docker-compose expects server version 1.18

# which docker-compose 
/usr/local/bin/docker-compose
# docker-compose ps
client and server don't have same version (client : 1.18, server: 1.15)

Even after stopping the daemon, I still get the same error message

# sudo killall docker
INFO[0288] Processing signal 'terminated' 
# docker ps
Error response from daemon: client and server don't have same version (client : 1.20, server: 1.15)

I know I can downgrade the docker client to match version 1.18 which docker-compose requires, but I still don't understand why the server version is reporting as 1.15 when the same binary client appears to be 1.20.

Supplemental question: how is the docker client still receiving an incorrect server version message when the docker daemon is stopped?

Try restarting the docker service after upgrading Docker (sudo service docker restart). That may be the cause of:

You still have an old version of Docker running.

I had a very similar issue, ugraded Docker, and kept running into the same error message until I restarted the service.
