  • 解决

在你原来运行命令的基础上,加如下,指定国内的源

[root@kmaster ~]# kubeadm init --image-repository registry.aliyuncs.com/google_containers --ignore-preflight-errors=Swap

另外

如果你的/usr/lib/systemd/system/docker.service 文件有类似如下两行配置

Environment="HTTPS_PROXY=http://www.ik8s.io:10080"
Environment="NO_PROXY=127.0.0.0/8,172.20.0.0/16"

注释或者删除掉就好了
