Docker学习笔记之一:简介和安装(Mac)

Docker安装

Install Docker Toolbox on Mac OS X

Docker Toolbox安装

下载Docker Toolbox,默认安装做了如下工作:

  • installs binaries for the Docker tools in /usr/local/bin
  • makes these binaries available to all users
  • installs VirtualBox; or updates any existing installation

Docker Toolbox启动

启动Docker Quickstart Terminal,当你看到这艘传的时候你就成功了。

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

Share images, automate workflows, and more with a free Docker Hub account:
