Nexus3 做docker hub问题处理

在使用 Nexus3 做镜像仓库做代理时，使用 docker login、docker pull 会报如下错误

[[email protected] ~]# docker login 172.16.248.62:5000
Username: admin
Password: 
Error response from daemon: login attempt to http://172.16.248.62:5000/v2/ failed with status: 401 Unauthorized
           

docker pull

[[email protected] ~]# docker pull 172.16.248.62:5000/xxx/xxx:v2.0.0
Error response from daemon: unauthorized: authentication required
