docker安装及加速配置

需要centos7版本

[root@localhost ~]# uname -r
3.10.0-514.el7.x86_64

第一步：更新当前软件：
[root@localhost ~]#yum update

第二步：添加Docker的yum源
[root@localhost ~]# cat /etc/yum.repos.d/docker.repo
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg


第三步：安装Docker
[root@localhost ~]# yum install docker-engine

至此安装完成。

设置Docker服务开机自启
[root@localhost ~]# systemctl enable docker.service

启动Docker服务
[root@localhost ~]# systemctl start docker

验证Docker是否安装成功
[root@localhost ~]# docker run --rm hello-world

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 ID:

由于国外的docker镜像仓库一般都比较慢，所以一般会使用国内的一些加速仓库，如阿里云

申请：https://cr.console.aliyun.com/#/accelerator

配置：

mkdir -p /etc/docker
cat /etc/docker/daemon.json
{
  "registry-mirrors": ["https://xxxxxxx.mirror.aliyuncs.com"]
}

https://xxxxxxx.mirror.aliyuncs.com替换成你申请到的地址。

sudo systemctl daemon-reload
sudo systemctl restart docker
