情况：
在使用docker企业级私有仓库时，推送镜像到仓库出现如下报错
[root@docker01 docker]# docker tag alpine:latest 10.0.0.12/library/alpine:latest [root@docker01 docker]# docker push 10.0.0.12/library/alpine:latest The push refers to repository [10.0.0.12/library/alpine] Get https://10.0.0.12/v2/: dial tcp 10.0.0.12:443: connect: connection refused
原因：
没有配置https证书,但是我们可以使用http协议进行访问
方法一：使用http协议访问
#在放docker镜像的服务器上面操作
#10.0.0.12为仓库地址
[root@docker01 docker]# vim /etc/docker/daemon.json
{
"insecure-registries": ["10.0.0.12"]
}
#重启docker
[root@docker01 docker]# systemctl restart docker
#登录harbor仓库
[root@docker01 docker]# docker login 10.0.0.12
Username: admin
Password:

Configure a credential helper to remove this warning. See

方法二：使用https访问

结果：
[root@docker01 docker]# docker push 10.0.0.12/library/alpine:latest The push refers to repository [10.0.0.12/library/alpine] 1bfeebd65323: Pushed latest: digest: sha256:57334c50959f26ce1ee025d08f136c2292c128f84e7b229d1b0da5dac89e9866 size: 528 [root@docker01 docker]#
