I have a basic docker container which I build using docker-compose (version 3) to bring up a basic LAMP stack.
The issue I am having is that files created inside the docker container are always owned by root, so I am unable to edit them locally.
I have tried setting the container www-data user to have the same uid as my local user, which works, but new files are still created by root.
How do I create file in the container that I can edit locally?
My compose file;
version: "3"
services:
webserver:
build:
context: ./docker/containers/webserver
container_name: 'apache7.1-webserver'
restart: 'always'
ports:
- "80:80"

volumes:

- ${VHOSTS_DIR}:/etc/apache2/sites-enabled
- ${APACHE_LOG_DIR}:/var/log/apache2
mysql:
build: ./docker/containers/mysql
container_name: 'apache7.1-mysql'
restart: 'always'
ports:

volumes:

- ${MYSQL_LOG_DIR}:/var/log/mysql
environment:
MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}

MYSQL_PASSWORD: ${MYSQL_PASSWORD}
redis:
container_name: 'apache7.1-redis'

You can set the user with the USER
directive https://docs.docker.com/engine/reference/builder/#user.
So you would need to for example add USER 1000
or USER www-data
in the Dockerfile.
