This might seem like a dumb question, but I am stuck here for 6 hours rn. and I need a way out. I am too tired to do anything else.
I am trying to change our blogs from WordPress to inside a docker container, so that we can move around it easily. I wrote a docker-compose file for the purpose and it ran smoothly the first time. But I made some mistakes on configs and missed to write the `HOME` and `SITEURL` on the docker-compose file in the beginning. Now, I can’t seem to change the `wp-config.php`. according to WordPress, it can’t be updated from the entrypoint script once it’s already been written. I tried a bunch of other scenarios:
- I tried to use `docker exec` command to update the wp-config.php file. bash does not have vim/nano there.
- I deleted all the containers and volumes and images, but still, it doesn’t change anything. I downed and re-uploaded the compose file many times, but nothing is changing.
I tried to delete the volume using `docker volume rm` command. but it shows an error, even though I have no container running.
`Error response from daemon: remove <project_name>_wordpress_data: volume is in use – [43ade39ba3a495154fefd9ccd79b2c2c53765482e2c7c4d2859b7051383839ae]
Here’s a snippet of my compose file. What should I do now? [I need to change the home and siteurl because the WordPress will be served from a different server.]

Let me know what I can do. Thanks in advance.
