Overlay on volumes in docker compose

General Discussions

Hey guys,

I hope you are well!

I’m relatively new to Docker, so I’m still learning how it all works. I am currently building WordPress environments using the OpenLiteSpeed ​​web server, following my Dockerfile and Docker Compose configuration.

However, I have a problem. I’m trying to create a persistent volume that maps to the WordPress HTML folder. But when docker-compose up is run, the WordPress files seem to disappear. It appears that when Docker Compose creates a folder on the host, it replaces the container folder in /opt/wordpress. If I run Compose without specifying “volumes:”, everything works fine. But as soon as I try to map the volume for persistence, the folder with the WordPress files is restored.
I put some spaces in the links in the dockerfile because as I am a new user, I can only publish with a maximum of 2 links in the message.

Could you help me find out what’s wrong?

Thanks!
