Error: client and server don't have same version

When using Docker through Boot2docker there is a possibility you’ve seen:

Error: client and server don’t have same version (client : X, server: X)

This error occurs because the version of Docker installed on the Boot2docker image and the version of Docker installed on the host machine (your mac) are not the same.

$ docker version
Client version: 1.3.0
Client API version: 1.15
Go version (client): go1.3.3
Git commit (client): c78088f
OS/Arch (client): darwin/amd64
2014/11/03 13:21:38 Error response from daemon: client and server don't have same version (client : 1.15, server: 1.14)

Or

$ docker build -t my_containers .
2014/11/03 13:13:06 Error: client and server don't have same version (client : 1.15, server: 1.14)

The solution to this error is to update the Boot2docker VM image using the provided CLI.

$ boot2docker stop # stop boot2docker running instances
$ boot2docker download # download and install the new VM image
$ boot2docker start # start the updated VM

Hope this helps!
