Docker-Harbor:推送镜像/登录失败（Error response from daemon: Get https://reg.harbor.com/v2/: dial tcp 192...）

推送镜像/登录失败（Error response from daemon: Get https://reg.harbor.com/v2/: dial tcp 192…）

搭建好Harbor之后，使用docker登录仓库，或者推送镜像到仓库时被拒绝。

[root@kube-node-1 harbor]# docker login reg.harbor.com
Authenticating with existing credentials...
Login did not succeed, error: Error response from daemon: Get https://reg.harbor.com/v2/: dial tcp 192.168.186.21:443: connect: connection refused

[root@kube-node-1 harbor]# docker push reg.harbor.com/harbor-test/nginx-offica
The push refers to repository [reg.harbor.com/harbor-test/nginx-offica]
Get https://reg.harbor.com/v2/: dial tcp 192.168.186.21:443: connect: connection refused

这是因为在使用docker的仓库时，Registry为了安全性考虑，默认是需要https证书支持。除了生成证书，配置https的办法之外，我们在实验环境中，还可以通过修改docker启动文件来解决。

如上图，在docker的启动文件添加--insecure-registry选项，后面可以使用IP或者可以解析的域名。
添加好之后，重新启动docker服务：

[root@kube-node-1 harbor]# systemctl daemon-reload
[root@kube-node-1 harbor]# systemctl restart docker

重启docker之后，可能会遇到Harbor无法正常访问的问题，是因为docker重启后，harbor相关的容器没有完全启动，只要将所有的harbor容器重启即可，最好先启动harbor-log这个容器。

可以使用命令 docker restart containerID逐个重启，也可以使用docker-compose进行重新启动：

[root@kube-node-1 harbor]# docker-compose stop
Stopping nginx             ... done
Stopping harbor-jobservice ... done
Stopping harbor-core       ... done
Stopping registry          ... done
Stopping harbor-portal     ... done
Stopping redis             ... done
Stopping registryctl       ... done
Stopping harbor-db         ... done
Stopping harbor-log        ... done
[root@kube-node-1 harbor]# docker-compose up -d
Starting harbor-log ... done
Starting redis ...
Starting harbor-db ...
Starting registryctl ...
Starting harbor-portal ...
Starting registry ... done
Starting harbor-core ... done
Starting harbor-jobservice ...
Starting nginx ... done

注意：这个启停操作需要在harbor的安装目录下使用，否则会报以下错误

[root@kube-node-1 ~]# docker-compose stop
ERROR:Can't find a suitable configuration file in this directory or anyparent. Are you in the right directory?Supported filenames: docker-compose.yml, docker-compose.yaml

重新登录

[root@kube-node-1 harbor]# docker login reg.harbor.com:80
Username: admin
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-storeLogin Succeeded

重新打包镜像并推送

[root@kube-node-1 harbor]# docker tag nginx:latest reg.harbor.com:80/harbor-test/nginx-offical
[root@kube-node-1 harbor]# docker push reg.harbor.com:80/harbor-test/nginx-offical
The push refers to repository [reg.harbor.com:80/harbor-test/nginx-offical]
