Creating a container in docker gets stuck

Question

I have a laravel app that uses docker. I also got myself a new laptop with windows and I've installed wsl 2 and docker. The problem I'm having is that when I try to create the container it seems to get stuck at this point

# gpg: keybox '/root/.gnupg/pubring.kbx' created

I'm not sure where I went wrong, because this is the first time it's ever happened.

Here is my Dockerfile. Where it says 'random-key' there was some values there that I wasn't sure if it was sensitive information so I just removed it.
