Docker系列二：docker安装

目录

1. Linux

2. CentOS Docker 安装

2.1 使用官方安装脚本自动安装

2.2 手动安装

2.2.1 卸载旧版本

2.2.2 安装 Docker Engine-Community

2.3 卸载 docker

3. Ubuntu Docker安装

---

1. Linux

linux系统下通用的安装方法，速度会慢，因为使用国外的源。这种方法都是安装的最新版本，使用国内源版本更新都会延迟。

$ sudo curl -sS https://get.docker.com/ | sh

测试

$ docker run hello-world
Unable to find image 'hello-world:latest' locally

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.
    (amd64)
 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

 如果机器有支持深度学习的GPU，可以继续执行如下命令以支持容器对gpu的调用[目前仅支持linux]：

# Add the package repositories
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker
