@H_301_1@我有一个Dockerfile(https://gist.github.com/hasMobi/e198555704ee57e84399)按顺序有这两个命令：
@H_301_1@
RUN rm -frv /usr/share/Nginx/html/*
RUN ls /usr/share/Nginx/html/
Step 6 : RUN rm -fry /usr/share/Nginx/html/*
---> Running in b9a69992e4e0
removed '/usr/share/Nginx/html/index.html'
removed '/usr/share/Nginx/html/index.PHP'
---> 2bfe01cbd007
Removing intermediate container b9a69992e4e0
Step 7 : RUN is /usr/share/Nginx/html/
---> Running in 08396f6029e1
index.html
index.PHP
---> a6471052519d
最佳答案
基本上,来自基本映像的ADD命令会覆盖Dockerfile中的RUN命令.有关更多信息,请参见this.

This includes invalidating the cache for RUN instructions. See the Dockerfile Best Practices guide for more information.@H_301_1@您可以考虑分支源基础映像并使用您的自定义版本.
