03-docker 镜像加速器

1.Docker 镜像加速器

当你下载安装的Docker Version不低于1.10时，建议直接通过daemon config进行配置。使用配置文件 /etc/docker/daemon.json（没有时新建该文件）

[root@docker03 ~]# tee /etc/docker/daemon.json <<-'EOF'
> {
>   "registry-mirrors": ["https://de378wx8.mirror.aliyuncs.com"]
> }
> EOF
{
  "registry-mirrors": ["https://de378wx8.mirror.aliyuncs.com"]
}
[root@docker03 ~]# cat /etc/docker/daemon.json 
{
  "registry-mirrors": ["https://de378wx8.mirror.aliyuncs.com"]
}

# 重启服务
[root@docker03 ~]# systemctl daemon-reload
[root@docker03 ~]# systemctl restart docke

 复制镜像地址

tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://de378wx8.mirror.aliyuncs.com"]
}
EOF

2.查看镜像加速器是否生效，可以看到xxxx.mirror.aliyuncs.com地址，表示已经生效

[root@docker03 ~]# docker info | tail -10
