docker Get "https://registry-1.docker.io/v2/": x509: certificate is valid for

前言

docker 在进行 build 时，报错：Get "https://registry-1.docker.io/v2/": x509: certificate is valid for

问题原因：Docker 客户端无法验证 Docker Hub 服务器的 SSL/TLS 证书

解决

在 /etc/docker/daemon.json 中新增国内镜像源：

   "registry-mirrors": [
            "https://6kx4zyno.mirror.aliyuncs.com",
            "https://1nj0zren.mirror.aliyuncs.com",
            "https://docker.mirrors.ustc.edu.cn",
            "http://f1361db2.m.daocloud.io",
            "https://registry.docker-cn.com",
            "http://hub-mirror.c.163.com",
            "https://mirror.ccs.tencentyun.com/",
            "https://dockerproxy.com",
            "https://docker.nju.edu.cn",
            "https://mirror.iscas.ac.cn",
            "https://docker.mirrors.sjtug.sjtu.edu.cn",
            "https://dockerhub.azk8s.cn",
            "https://docker.m.daocloud.io"
        ],

systemctl daemon-reload

systemctl restart docker

重启 docker，问题解决！
