ERROR: client is newer than server (client API version: 1.22, server API version: 1.21)

[wil93]

After installing the right version of docker-py (for the latest docker-compose):

ioi@cms:~$ pip list | grep docker
docker-compose (1.6.0rc2)
docker-py (1.7.0-rc3)
dockerpty (0.3.4)

I now get this error:

ioi@cms:~/server$ docker-compose ps
ERROR: client is newer than server (client API version: 1.22, server API version: 1.21)

Even though:

ioi@cms:~/server$ docker version
Client:
 Version:      1.9.1
 API version:  1.21
 Go version:   go1.4.2
 Git commit:   a34a1d5
 Built:        Fri Nov 20 13:12:04 UTC 2015
 OS/Arch:      linux/amd64

Server:
 Version:      1.9.1
 API version:  1.21
 Go version:   go1.4.2
 Git commit:   a34a1d5
 Built:        Fri Nov 20 13:12:04 UTC 2015
 OS/Arch:      linux/amd64

What could be the issue?

ah, yes, sorry about that.

In the ansible docs, you pass "docker_api_version" in the playbook.
