Docker Toolbox / Mac安装后设置DOCKER_HOST [英] Setting DOCKER_HOST after Docker Toolbox/Mac install

问题描述

Mac这里。我通过工具箱安装Docker，所有Docker命令都产生相同的错误：

Mac here. I installed Docker via the Toolbox and all Docker commands yield the same error:

myuser@mymachine:~/tmp$docker info
Get http:///var/run/docker.sock/v1.20/info: dial unix /var/run/docker.sock: no such file or directory.
* Are you trying to connect to a TLS-enabled daemon without TLS?

myuser@mymachine:~/tmp$sudo docker info
Password:
Get http:///var/run/docker.sock/v1.20/info: dial unix /var/run/docker.sock: no such file or directory.
* Are you trying to connect to a TLS-enabled daemon without TLS?
* Is your docker daemon up and running?

myuser@mymachine:~/tmp$docker -v
Docker version 1.8.1, build d12ea79

Google结果 | 出现此错误表示工具箱未正确安装，而且其中之一（或全部）以下env vars需要设置：

Google results | for this error indicate that the Toolbox did not install correctly, and that one of (or all) of the following env vars need to be set:

• DOCKER_HOST ;和/或


• DOCKER_CERT_PATH ;和/或


• DOCKER_TLS_VERIFY

• DOCKER_HOST; and/or
• DOCKER_CERT_PATH; and/or
• DOCKER_TLS_VERIFY

我已验证 DOCKER_HOST 未在我的机器上设置（既不是 env 也不是 echo $ DOCKER_HOST 显示它）。所以我的关注：

I have verified DOCKER_HOST is not set on my machine (neither env nor echo $DOCKER_HOST show it). So my concerns:

• 这些env vars是什么，他们做什么？他们的正确价值是什么？


• 如何永久性地设置它们以使机器重新启动？

运行目前为止一个答案建议的命令：

Running the commands suggested by the one answer so far:

myuser@mymachine:~/tmp$docker-machine start default
Error: Host does not exist: default
myuser@mymachine:~/tmp$eval $(docker-machine env default)
Error: Host does not exist: default

想法？

推荐答案

运行：

$ docker-machine start default
$ eval $(docker-machine env default)

然后重试。

这些环境变量将您的本地Docker客户端指向在VM中运行的Docker引擎。上述命令将适当地进行设置。

Those environment variables point your local Docker client to the Docker engine running in the VM. The above commands will set them appropriately.
