前言

docker login harbor x509: certificate signed by unknown authority

解决

打开 /etc/docker/daemon.json，如果没有这个文件新增即可

vim /etc/docker/daemon.json

加入 insecure-registries

{
    "insecure-registries":["harbor.xxxx.com:1111"]
}

重启 docker

sudo systemctl docker

重新登录即可

docker login harbor.xxxx.com:1111
