How to be user www-data?

[Emporea]

I have a mounted storage whose owner is www-data(33) and this shouldnt be changed.
Thus I want to use code-server with the uid 33.

Should I change the uid of coder (1000) to 33 or can I do something else?

I tried alot of stuff but i keep getting errors.

I tried setting USER 33 in my Dockerfile. If I do this I keep getting errors when install code-server extensions about permissions i dont have about /var/www or something. Also the user is still called coder ( which would be fine if the uid was 33).

Then I tried setting user: 33:33 in my docker-compose.yml file.
This does work to some extent, atleast the fixuid script gets started, but the container crashes after about 1 minute without serving anything on the web nor producing any logs (atleast not the docker container).

I tried setting DOCKER_USER=www-data, but this doesnt change anything. The default home directory is still /home/coder.

I am confused.

How can I be a user with uid 33, while being able to already install some extensions in the Dockerfile?

Thanks for help.

Seems like a good question for @code-asher

I believe we keep the home directory as /home/coder because we are not able to move bind mounts. But if you use -u "33:33" the permissions should be correct. You might just need to mount your directory over /home/coder like -v /path/to/www-data:/home/coder.

But it looks like you have already tried that so I am not sure. I can give it a try some time this week.

This i would appreciate!

Initial setup:

$ whoami && id
coder
uid=1000(coder) gid=1000(coder) groups=1000(coder),999(docker)
$ sudo mkdir /var/www
$ sudo chown -R www-data: /var/www

This seems to work for me to run as www-data with my data directory set to /var/www:

docker run -it --name code-server -p 127.0.0.1:8080:8080 -e SHELL=/bin/bash -v "/var/www:/var/www" --user www-data codercom/code-server:latest --user-data-dir /var/www

I set SHELL since www-data by default has no shell.
