報錯現象

[root@localhost ~]# docker pull 20.0.0.53/project/tomcat
Using default tag: latest
Error response from daemon: pull access denied for 20.0.0.53/project/tomcat, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

解決思路和方法

問題點：缺少倉庫的憑據
解決方法：
需要登錄到harbor中，獲取.docker這個憑證，才能下載

docker login 20.0.0.53
ls -a   '查看.docker'
