David Young commented on MESOS-2986:
------------------------------------

In Fedora 22, docker 1.7 will report version as {{1.7.0.fc22}}, this will break mesos slave from start up.
{code}
docker --version
Docker version 1.7.0.fc22, build 74e7a7a/1.7.0
{code}

{code}
Failed to create a containerizer: Could not create DockerContainerizer: Failed to create docker: Failed to get docker version: Failed to parse docker version: Version string has 4 components; maximum 3 components allowed
{code}

> We currently use docker version to get Docker version, in Docker master branch and soon in Docker 1.8 [1] the output for this command changes. The solution for now will be to use the unchanged docker --version output, in the long term we should consider stop using the cli and use the API instead.
