1.2 yum安装最新版的docker

一、yum安装DOCKER

yum install docker -y

 

二、查看docker版本号

[[email protected] docker.service.d]# docker version

 Package version: docker-1.13.1-75.git8633870.el7.centos.x86_64
 Go version:      go1.9.4
 Git commit:      8633870/1.13.1

[[email protected] docker.service.d]# cd /etc/systemd/system/
[[email protected] system]# ll

三、配置docker的下载源

3.1修改参数，进入目录/etc/docker，修改daemon.json文件。

[[email protected] docker]# pwd
/etc/docker
[[email protected] docker]# ll
总用量 24
drwxr-xr-x 5 root root  4096 11月 21 14:30 certs.d
-rw-r--r-- 1 root root   112 11月 21 14:43 daemon.json
-rw------- 1 root root   244 11月 21 10:19 key.json
-rw-r--r-- 1 root root 10837 9月  29 03:07 seccomp.json

 

3.2 修改daemon.json文件

[[email protected] docker]# cat daemon.json 
{}
[[email protected] docker]# vim daemon.json 
[[email protected] docker]# systemctl daemon-reload 
[[email protected] docker]# systemctl restart docker

 

修改daemon.json文件k的内容：

{
    "registry-mirrors":["https://frz7i079.mirror.aliyuncs.com"],"insecure-registries":["0.0.0.0/0"] 
}
