chenxing d1ddeddb67 Fix the Prechecks failed while checking docker version ... In Docker version 18.01.0-ce, "docker version" command uses the "\t" to format the result, which will cause the prechecks failed. There is a workaround that using "docker --version" command instead of "docker version" can get everything running. Also, using "docker --version" to check the version of docker is more specific and effective. backport: pike ocata Change-Id: Ie5efe1888afc3be11441a88d627db62e1575f3ed Closes-Bug: #1742869		2018-01-22 16:58:48 +08:00
