官方脚本安装

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

这里直接使用批量脚本，通过阿里云镜像安装，如果想掌握安装过程，需要继续往下看

使用阿里云镜像安装

参考官方文档 https://yq.aliyun.com/articles/110806?spm=5176.8351553.0.0.6a721991LqELWA

# step 1: 安装必要的一些系统工具
sudo apt-get update
sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
# step 2: 安装GPG证书
curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
# Step 3: 写入软件源信息
sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
# Step 4: 更新并安装 Docker-CE
sudo apt-get update
sudo apt-get -y install docker-ce
# 安装的版本可能很低，建议更换后面的方式安装
sudo apt-get -y install docker-compose
# python-pip
sudo apt-get -y install python-pip
# update pip
sudo pip install --upgrade pip
# install docker-compose
sudo pip install docker-compose
# Cannot uninstall 'texttable'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
sudo pip install docker-compose --ignore-installed texttable

# 安装指定版本的Docker-CE:
# Step 1: 查找Docker-CE的版本:
# apt-cache madison docker-ce
# docker-ce | 17.03.1~ce-0~ubuntu-xenial | http://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages
# docker-ce | 17.03.0~ce-0~ubuntu-xenial | http://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages
# Step 2: 安装指定版本的Docker-CE: (VERSION 例如上面的 17.03.1~ce-0~ubuntu-xenial)
# sudo apt-get -y install docker-ce=[VERSION]

16.04 安装

• set resource

# update package
sudo apt-get update
# Install packages
sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common
# add GPG key
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
# set up the stable repository
sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

• install docker-ce

sudo apt-get update
sudo apt-get install docker-ce

• Uninstall Docker CE

# Uninstall the Docker CE package
sudo apt-get purge docker-ce
# remove  Images, containers, volumes, or customized configuration files
sudo rm -rf /var/lib/docker

14.04安装docker

通过apt-get安装

apt-get update
apt-get install docker.io
ln -sf /usr/bin/docker.io /usr/local/bin/docker
sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io
apt-get install apt-transport-https
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
sh -c "echo deb https://get.docker.io/ubuntu docker main  > /etc/apt/sources.list.d/docker.list"
apt-get update
apt-get install lxc-docker

通过下载二进制文件安装

curl -sSL https://get.docker.com/ | sh

这种方式启动docker若出现下面错误，请安装apparmor软件

Error loading docker apparmor profile: fork/exec /sbin/apparmor_parser: no such file or directory () 

sudo apt-get install apparmor

安装后检查安装

sudo docker run hello-world

sudo docker pull daocloud.io/library/ubuntu:latest

去除每次sudo运行docker命令

需要添加组

# Add the docker group if it doesn't already exist.
$ sudo groupadd docker
#改完后需要重新登陆用户
$ sudo gpasswd -a ${USER} docker
# 更新用户组
$ newgrp docker

不要让docker 运行在 root 下，所以给某个用户 docker 运行权限是必要的
