server1=192.168.1.40
server2=192.168.205.10
自己在server1机器上搭建
systemctl start docker
docker run -d -p 5000:5000 --restart always --name registry registry:2
server2测试server1能不能通：
telnet 192.168.1.40 5000
开始构建：
docker build -t 192.168.1.40:5000/hello-word .
#文件名写服务器的ip:5000/hello-word .
docker push 192.168.1.40:5000/hello-word
The push refers to repository [192.168.1.40:5000/hello-word]
Get https://192.168.1.40:5000/v2/: http: server gave HTTP response to HTTPS client这时候就需要添加一下认证。
vim /etc/docker/daemon.json
添加
{ "insecure-registries":["192.168.1.40:5000"] }
[root@docker-host vim]# systemctl restart docker
[root@docker-host vim]# docker push 192.168.1.40:5000/hello-word
The push refers to repository [192.168.1.40:5000/hello-word]
docker registry api 可以验证是否可以成功在浏览器上打开server端的地址：
http://192.168.1.40:5000/v2/_catalog
浏览器显示：
{"repositories":["hello-word"]}
