在Ubuntu16.04中安装Docker Ce

在Ubuntu16.04中安装Docker Ce

卸载旧版本

#如果之前安装过docker.io，没有跳过

eric@userver:~$ sudo apt-get remove docker docker-engine docker.io

​

安装AUFS 内核驱动模块

#aufs是docker存储驱动推荐的内核模块，如果系统没有安装，执行下面脚本

eric@userver:~$ sudo apt-get install linux-image-extra-$(uname -r) linux-image-extra-virtual

安装镜像源

#添加使用https传输软件包及CA证书,保证官方源不被篡改

eric@userver:~$ sudo apt update
eric@userver:~$ sudo apt install apt-transport-https ca-certificates curl software-properties-common

#国内源，推荐

eric@userver:~$ curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

#官方源，速度较慢，有可能下载失败

eric@userver:~$ curl -fsSL https://download.docke a409
r.com/linux/ubuntu/gpg | sudo apt-key add -

添加软件源

#向soruce.list中添加Docker软件源

eric@userver:~$ sudo add-apt-repository  "deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

安装Docker CE

#使用脚本自动安装（推荐）

eric@userver:~$ curl -fsSL get.docker.com -o get-docker.sh
eric@userver:~$ sudo sh get-docker.sh --mirror Aliyun

#apt 安装docker ce

eric@userver:~$ sudo apt-get update
eric@userver:~$ sudo apt-get install docker-ce

启动Docker CE

eric@userver:~$ sudo systemctl enable docker
eric@userver:~$ sudo systemctl start docker

#ubuntu14.04使用下面命令

eric@userver:~$ sudo service docker start

​

将当前用户加入docker组

#默认情况，docker命令会使用unix socket 与docker引擎通讯，只有root和docker的用户才能访问

#建立docker组：默认安装docker时候已经生成

eric@userver:~$ sudo groupadd docker

#将当前用户加入 docker 组

sudo usermod -aG docker $USER

#退出终端，重新登录使生效

​

测试

eric@userver:~$ docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Digest: sha256:445b2fe9afea8b4aa0b2f27fe49dd6ad130dfe7a8fd0832be5de99625dad47cd

Hello from Docker! #输出信息 成功
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

使用镜像加速

由于国内网络问题，拉取dokcer镜像十分缓慢，建议配置国内镜像加速。

我使用的是阿里云加速(https://yq.aliyun.com/articles/29941)
