Docker如何获取镜像

可以使用 docker pull 命令来从仓库获取所需要的镜像。
如果源不正确,可以使用阿里云:
https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors

针对Docker客户端版本大于 1.10.0 的用户

您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器

{
  "registry-mirrors" : ["https://docker.registry.cyou",
"https://docker-cf.registry.cyou",
"https://dockercf.jsdelivr.fyi",
"https://docker.jsdelivr.fyi",
"https://dockertest.jsdelivr.fyi",
"https://mirror.aliyuncs.com",
"https://dockerproxy.com",
"https://mirror.baidubce.com",
"https://docker.m.daocloud.io",
"https://docker.nju.edu.cn",
"https://docker.mirrors.sjtug.sjtu.edu.cn",
"https://docker.mirrors.ustc.edu.cn",
"https://mirror.iscas.ac.cn",
"https://docker.rainbond.cc",
"https://do.nark.eu.org",
"https://dc.j8.work",
"https://dockerproxy.com",
"https://gst6rzl9.mirror.aliyuncs.com",
"https://registry.docker-cn.com",
"http://hub-mirror.c.163.com",
"http://mirrors.ustc.edu.cn/",
"https://mirrors.tuna.tsinghua.edu.cn/",
"http://mirrors.sohu.com/" 
],
 "insecure-registries" : [
    "registry.docker-cn.com",
    "docker.mirrors.ustc.edu.cn"
    ],
"debug": true,
"experimental": false
}
sudo systemctl daemon-reload
sudo systemctl restart docker

直接拉取镜像

使用阿里云镜像仓库

docker pull registry.cn-hangzhou.aliyuncs.com/library/hello-world:latest

或使用网易镜像

docker pull hub-mirror.c.163.com/library/hello-world:latest

docker pull ccr.ccs.tencentyun.com/library/hello-world:latest
