I am building my first customs Docker with Docker compose and I feel I am very close to finishing it but I have having an issue with what seem to be the entrypoint

FYI i am tryng to deploy a django app with postgres, nginx, certbot, letsencrypt

this is what I am seeing:

certbot_1 | /data/entrypoint.sh: exec: line 14: certbot: not found nginx_1 | /data/entrypoint.sh: exec: line 14: run: not found

EDIT: I was able to make them run with the editted code but Ngnix exits with a code 0 and I don't know why and wont run

I have tried changing path with no luck

I am not sure what I am doing wrong

any advice you can provide would be great!
