1、如果dockerhub的https证书是非权威机构的需要执行，需要添加证书信任

[email protected]:# echo -n | openssl s_client -showcerts -connect dockerhub.xx.com:443 2>/dev/null | sed -ne ‘/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p‘ >> /etc/ssl/certs/dockerhub.xx.com.crt
[email protected]:# update-ca-certificates

2、修改/etc/docker/daemon.json

[email protected]:# cat /etc/docker/daemon.json 
{
        "registry-mirrors": ["https://dockerhub.xx.com"]
}

最后重启docker

[email protected]:# service docker restart
