Laravel docker image "Could not open input file: /var/www/html/artisan" - php

Question

I'm attempting to build and run a Laravel docker image which was originally generated via Laravel sail. When using docker-compose up, it correctly runs and I am able to access the site. Running docker build docker/7.4/ -t <tagname> followed by docker run <tagname> results in the following error logs however:
I have tracked this error down to my supervisord.conf file, where it is trying to call /var/www/html/artisan serve, but is seemingly unable to resolve it.
supervisord.conf:
[supervisord]
nodaemon=true
user=root
logfile=/var/log/supervisor/supervisord.log
pidfile=/var/run/supervisord.pid
[program:php]
command=/usr/bin/php -d variables_order=EGPCS /var/www/html/artisan serve --host=0.0.0.0 --port=80
user=sail
environment=LARAVEL_SAIL="1"
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
Here is also the Dockerfile I'm using, as well as the start-container script it runs

I am fairly new to using docker, so the process is somewhat confusing to me. Any help on where to look for this or how to debug it would be greatly appreciated - as well as an explanation as to why it's unable to resolve the php artisan command in supervisord.conf

Answer 1

Looking at your Dockerfile, you don't have a copy statement which copies the your source code to the container. And in your docker compose you would would be sharing that code using volumes. Hence your code works fine in docker-compose up. But in case of docker run <image> that volume is not shared and hence the error

Answer 2

simply add COPY . /var/www/html above COPY start-container /usr/local/bin/start-container
