如何在 OSX 上启动 docker-机器？

Question

我昨天第一次安装并使用了docker，

一切正常，但昨天晚上我关闭了计算机。

今天我启动了它，我想开发我的 docker 应用程序，但是当我尝试运行它就像

docker run -d -p 8080:8080 container/app

我收到错误：

docker: Cannot connect to the Docker daemon. Is the docker daemon running on this host?.

但是我找不到如何再次启动docker...

想法？

编辑：

eval "$(docker-machine env default)"

结果：

Error checking TLS connection: Host is not running

Answer 1

如果 "default" 机器不是运行ning，docker-machine env default 命令将不起作用。

您可以运行 docker-machine ls 命令，它会为您提供已配置的机器列表及其当前状态（运行ning，已停止）。

如果机器停止，运行 docker-machine start <name-of-machine>。之后你应该可以使用

设置环境变量

eval "$(docker-machine env default)"

请阅读 https://docs.docker.com/machine/overview 上的文档了解更多详情

Answer 2

在我运行命令 $ docker-machine start default 之后，我收到

的消息

Starting "default"...

文末提供解决方案，

This is a known VirtualBox bug. Let's try to recover anyway...

我卸载了然后，尝试重新安装VirtualBox。还是一样。

然后，我在机器的任何位置允许应用程序，这解决了问题：

允许来自任何地方的应用程序：sudo spctl --master-disable
