Brew安装docker不包括docker引擎？

尝试从brew设置docker，但是任何正式公式中似乎都未包含该引擎。

brew install docker-machine docker-compose

因此，这些仅安装客户端吗？引擎/守护程序没有小桶吗？

请尝试跑步

brew install docker

这将安装Docker引擎，这将需要Docker-Machine（+ VirtualBox）在Mac上运行。

如果要安装不需要virtualbox的较新的 Docker for Mac，可以通过Homebrew的Cask进行安装：

brew cask install docker
open /Applications/Docker.app

以下步骤可在macOS Sierra 10.12.4上正常运行。请注意，brew安装Docker之后，该docker命令（符号链接）在处不可用/usr/local/bin。首次运行Docker应用程序将创建此符号链接。请参阅下面的详细步骤。

1. 安装Docker

   brew cask install docker
   

2. 启动Docker。

   • 按⌘+调Space出Spotlight搜索并输入Docker以启动Docker。
   • 在Docker需要特权访问对话框中，单击确定。
   • 输入密码，然后单击 确定。

   当以这种方式启动Docker时，状态菜单中会出现一个Docker whale图标。一旦鲸鱼图标出现，对于符号链接docker，docker-compose，docker-credential-osxkeychain并docker-machine在创建/usr/local/bin。

   $ ls -l /usr/local/bin/docker*
   lrwxr-xr-x  1 susam  domain Users  67 Apr 12 14:14 /usr/local/bin/docker -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-compose -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-compose
   lrwxr-xr-x  1 susam  domain Users  90 Apr 12 14:14 /usr/local/bin/docker-credential-osxkeychain -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-credential-osxkeychain
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-machine -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-machine
   

3. 单击状态菜单中的docker whale图标，等待它显示Docker正在运行。

   

4. 测试docker工作正常。

   $ docker run hello-world
   Unable to find image 'hello-world:latest' locally
   latest: Pulling from library/hello-world
   78445dd45222: Pull complete
   Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7
   Status: Downloaded newer image for hello-world:latest
   
   Hello from Docker!
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash

   $ docker version

   Server:

    API version:  1.27 (minimum version 1.12)

    Experimental: true
   

5. 如果您要使用 docker-machine创建虚拟机，请安装VirtualBox。

   brew cask install virtualbox
   

   请注意，如果未安装VirtualBox，则docker-machine 失败并显示以下错误。

   $ docker-machine create manager
   Running pre-create checks...
   Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
   

要使用自制软件为Mac安装Docker：

brew cask install docker

要安装命令行完成：

brew install bash-completion
brew install docker-completion
brew install docker-compose-completion
brew install docker-machine-completion
