docker笔记配置镜像

　　一、配置mirror下载安装docker参考菜鸟教程 https://www.runoob.com/docker/centos-docker-install.html
　　切换到你临时文件夹下，下载安装脚本，指定下载的脚本文件名称为get-docker.shcurl -fsSL https://get.docker.com -o get-docker.sh
　　get-docker.sh脚本内容镜像源是境外，可能会慢，执行脚本的时候可以重新指定镜像源。sh get-docker.sh --mirror Aliyun
　　下载的过程会使用公钥、私钥检测下载的包是否被攻击修改过。安装完成标志：================================================================================  To run Docker as a non-privileged user, consider setting up the Docker daemon in rootless mode for your user:      dockerd-rootless-setuptool.sh install  Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.   To run the Docker daemon as a fully privileged service, but granting non-root users access, refer to https://docs.docker.com/go/daemon-access/  WARNING: Access to the remote API on a privileged Docker daemon is equivalent          to root access on the host. Refer to the ＂Docker daemon attack surface＂          documentation for details: https://docs.docker.com/go/attack-surface/  ================================================================================
　　改完配置之后重启服务步骤systemctl daemon-reload
　　重启dockersystemctl restart docker
　　安装完成。
　　二、配置docke pull镜像
　　下载镜像的时候docker pull:xxx会很慢，配置pull镜像解决：
　　在  /etc/docker/daemon.json文件(没有则创建)中添加下面参数(此处使用的是中国科技大学/阿里/网易云、百度的docker镜像源，可以单个可以多个)  {    ＂registry-mirrors＂ : [        ＂https://docker.mirrors.ustc.edu.cn＂,        ＂https://ustc-edu-cn.mirror.aliyuncs.com＂,        ＂https://hub-mirror.c.163.com＂,        ＂https://mirror.baidubce.com＂     ] }
　　重启docker systemctl daemon-reload systemctl restart docker
　　执行docker info 查看结果：.... 省略....  Docker Root Dir: /var/lib/docker  Debug Mode: false  Registry: https://index.docker.io/v1/  Labels:  Experimental: false  Insecure Registries:   127.0.0.0/8  Registry Mirrors:   https://docker.mirrors.ustc.edu.cn/   https://ustc-edu-cn.mirror.aliyuncs.com/   https://hub-mirror.c.163.com/   https://mirror.baidubce.com/  Live Restore Enabled: false
