错误：docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp 108.160.170.41:443: i/o timeout.
1、配置阿里云镜像加速器
可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://msy2rq3m.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker如果失败，则步骤2
2、在/etc/docker/daemon.json文件中
[root@localhost docker]# cat daemon.json
{
"registry-mirrors": [
"https://ghcr.geekery.cn",
"https://hub.geekery.cn",
"https://docker.m.daocloud.io",
"https://docker.rainbond.cc",
"https://docker.1panel.live"
]
}[root@localhost docker]# systemctl daemon-reload [root@localhost docker]# systemctl restart docker
3、拉去一个镜像测试
[root@localhost docker]# docker run -d -p 80:80 --name webserver nginx Unable to find image 'nginx:latest' locally latest: Pulling from library/nginx 2d429b9e73a6: Pull complete 9b1039c85176: Pull complete 9ad567d3b8a2: Pull complete 773c63cd62e4: Pull complete 1d2712910bdf: Pull complete 4b0adc47c460: Pull complete 171eebbdf235: Pull complete Digest: sha256:bc5eac5eafc581aeda3008b4b1f07ebba230de2f27d47767129a6a905c84f470 Status: Downloaded newer image for nginx:latest 660b32551340b6938cbad87a7b7a25d9274b09491f39cbe8e013c3fd0fa54271
完成！
