导读 在2017年的3月1号之后,Docker的版本命名分为CE(Community Edition,社区版)版本和EE(Enterprise Edition,企业版)版本。我们使用CE版本就够了。

基本主流的操作系统都可以安装。
我非常建议大家在Linux下安装,而不是在Windows下,因为Linux版Docker是企业生产用的。

服务器的系统是CentOS7.4的
[root@VM_82_178_centos ~]# cat /etc/RedHat-release 
CentOS Linux release 7.4.1708 (Core)

#安装依赖包
yum install -y yum-utils device-mapper-persistent-data lvm2
#添加Docker软件包源
yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
#安装Docker CE
yum install docker-ce -y
#启动
systemctl start docker
#开机启动
systemctl enable docker
#查看Docker信息
docker info
2.Ubuntu 上安装
apt-get update
安装证书:

apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

添加docker源的key:

sudo apt-key fingerprint 0EBFCD88

pub  4096R/0EBFCD88 2017-02-22
      Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid                  Docker Release (CE deb) 
sub  4096R/F273FCD8 2017-02-22

添加docker软件包源:

sudo add-apt-repository \
  "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) \
  stable"

跟新apt包索引:
sudo apt-get update

安装docker ce
apt-get install docker-ce
3.配置Docker加速器

Docker Hub 提供众多镜像,你可以从中自由下载数十万计的免费应用镜像, 这些镜像作为 docker 生态圈的基石,是我们使用和学习 docker 不可或缺的资源。为了解决国内用户使用 Docker Hub 时遇到的稳定性及速度问题 DaoCloud 推出永久免费的新一代加速器服务。
Linux:

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://bc437cce.m.daocloud.io

[root@localhost ~]#  curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://bc437cce.m.daocloud.io
docker version >= 1.12
{"registry-mirrors": ["http://bc437cce.m.daocloud.io"]}
Success.
You need to restart docker to take effect: sudo systemctl restart docker 
[root@localhost ~]# 
[root@localhost ~]# systemctl  restart docker
[root@localhost ~]# systemctl  stop docker
[root@localhost ~]# ps -ef|grep docker
root      15185  3300  0 01:39 pts/1    00:00:00 grep --color=auto docker
[root@localhost ~]# systemctl  start docker
[root@localhost ~]# ps -ef|grep docker
root      15191      1  2 01:39 ?        00:00:00 /usr/bin/dockerd
root      15198  15191  0 01:39 ?        00:00:00 docker-containerd --config /var/run/docker/containerd/containerd.toml
root      15325  3300  0 01:39 pts/1    00:00:00 grep --color=auto docker
[root@localhost ~]#
