如何配置国内docker镜像源？

安装docker

chattr -i /etc/passwd
chattr -i /etc/shadow
chattr -i /etc/group
chattr -i  /etc/gshadow# 下载slirp4netns rpm包
wget https://1407433742.rsc.cdn77.org/c7-extras.x86_64/slirp4netns/20200428221211/0.4.3-4.el7_8.x86_64/slirp4netns-0.4.3-4.el7_8.x86_64.rpm# 安装rpm包
yum install -y slirp4netns-0.4.3-4.el7_8.x86_64.rpm# 下载docker软件镜像源repo文件
wget https://download.docker.com/linux/centos/docker-ce.repo# 将初始的docker官方镜像地址改为THU镜像地址
sed -i 's+https://download.docker.com+https://mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo# 安装docker
yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

配置docker国内镜像源

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors": ["https://proxy.1panel.live/","https://docker.1ms.run/","https://hub.geekery.cn/","https://docker.m.daocloud.io/","https://docker.rainbond.cc/","https://docker.1panel.live/"]
}
EOF# 重启docker
sudo systemctl daemon-reload
sudo systemctl restart docker# 输出上面配置的docker镜像源即为正常，详见下图
docker info | grep -C 10 'Registry Mirrors'# 测试拉取镜像
docker pull nginx
