docker私有库安装报错处理--net/http: TLS handshake timeout.

安装私有库，报错如下

[root@ip-10-249-100-205 ~]# docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry

Unable to find image ‘registry:latest’ locally

http: TLS handshake timeout.

原因：据说是被国家屏蔽了

方法一
不用官方的dockhub了，转而使用国内的仓库daocloud
echo “DOCKER_OPTS=\“\$DOCKER_OPTS —registry-mirror=http://f2d6cb40.m.daocloud.io\\“” | sudo tee -a /etc/default/docker
service docker restart
/bin/systemctl restart docker.service

重启docker服务后，再次push的结果

方法二：
[root@ip-10-249-100-205 data]# vi /etc/docker/daemon.json 加入一下国内库
{ “registry-mirrors”: [“https://registry.docker-cn.com"\]\}

/bin/systemctl restart docker.service

方法三：
mkdir -p certs && openssl req \
-newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key \
-x509 -days 365 -out certs/domain.crt

/bin/systemctl restart docker.service

网上找的方法不知道是我用的不对还是怎么回事，都很慢。
方法四：
我自己想了半天，把dns修改为8.8.8.8
再执行瞬间完事，也有可能是上面的那个配置生效了。
