404 error occurs when accessing the homepage of tomcat started in Docker mode

Scenario:

When starting tomcat in docker (version 8.5.50 downloaded from Alibaba Cloud), a 404 error occurred when accessing the tomcat homepage. I searched for many tutorials online but could not find a solution. Finally, I found the problem in the video explanation (I don't know if it was the problem with the version I downloaded)

Specific situation:

Use the command: docker exec -it to run the tomcat container ID /bin/bash to enter the tomcat directory

Enter the webapps folder and find that it is empty (the default welcome page of tomcat should actually be placed in the path: webapps/ROOT/index.jsp or index.html)

I found that there was a webapps.dist file next to it. When I entered it, I found that all the files that should have been in the webapps file were in the webapps.dist file. Now I don’t know why! ! !

picture:

Rename webapps.dist to webapps. The original webapps (empty file) can be deleted or renamed to another name: mv webapps.dist webapps

Note: If it is on the server, remember to open the mapped host port, otherwise it will not be accessible.
