I'm just starting out with development using docker. The file on the local storage(in the Linux file system) was initially owned by www-data so I changed it to my linux username using sudo chown -R username:username wordpress/ because it wasn't writeable. But doing this doesn't allow me to upload files(from wordpress interface) or write to files inside the nginx container unless the ownership is changed back to www-data:www-data.

Things I've tried:

1. Starting a bash session inside the nginx container with docker exec -it <cname> bash and changing the ownership of the uploads directory and writing files to my username.(after adding user with adduser username)
2. Changing the nginx user within the bash session to my username using user username username

I don't know what else to try except sudo chmod -R a rwx in the main directory.

CodePudding user response：

Refering to this answer, this is how I resolved my issue:

1. Add your user to the www-data group

   sudo usermod -a -G www-data username

2. Give rw permissions to the www-data group(f flag applies the permissions only to files and leaves the directories)

   sudo find wordpress -type f -exec chmod g rw {}
