Docker setup on WSL for a Laravel website

Question

I have entered into the WSL terminal the following command:

docker compose build --no-cache && docker compose up

This is what happened:

I have not downloaded anything outside of Docker on this computer and I have cloned this "backend" from the repository.

I have no experience in Docker or Laravel.

What methods should I start with to fix this?

Answer 1

The option -g in the groupadd command needs to be numerical, you can't use use the word sail.

See Ubuntu's documentation about that command and option here.
