导致这种情况的原因暂时不明，不过经过一翻摸索找到一个解决办法

docker psCannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

解决办法如下：

通过命令查看容器名称

$docker-machine lsNAME       ACTIVE   DRIVER      STATE   URL   SWARM   DOCKER   ERRORSdefault    -        virtualbox  Saved                 Unknown   defaultd   -        virtualbox  Saved                 Unknown

然后执行如下命令启动容器：

$docker-machine start defaultStarting "default"...(default) Waiting for an IP...Machine "default" was started.Waiting for SSH to be available...Detecting the provisioner...Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command.

在执行如下命令：

$docker-machine env defaultexport DOCKER_TLS_VERIFY="1"export DOCKER_HOST="tcp://192.168.99.100:2376"export DOCKER_CERT_PATH="/Users/jack/.docker/machine/machines/default"export DOCKER_MACHINE_NAME="default"# Run this command to configure your shell: # eval $(docker-machine env default)

最后执行如下命令：

$eval $(docker-machine env default)

查看一下容器的情况：

$docker psCONTAINER ID        IMAGE                      COMMAND                  CREATED             STATUS               PORTS                               NAMESbe93b47435fd        mysql/mysql-server:latest  "/entrypoint.sh my..."   2 weeks ago         Up 3 days (healthy)   0.0.0.0:3306->3306/tcp, 33060/tcp   mysql

成功！！
