I'm relatively new to Docker - I'm trying to build a system to run a Symfony 4 app, comprising of PHP-FPM, nginx and MySQL.
Everything works as it should except one thing. When the PHP-FPM container boots, I want to run:
#!/bin/bash
composer install
bin/console doctrine:database:create --if-not-exists
bin/console doctrine:schema:update --force
bin/console doctrine:fixtures:load --no-interaction
I created a script with these commands in and then edited my DockerFile as follows:
COPY ./docker/php/startup.sh /usr/local/bin/startup.sh
RUN ["chmod", "+x", "/usr/local/bin/startup.sh"]
ENTRYPOINT ["/usr/local/bin/startup.sh"]
The issue I'm having is that when I run docker-compose build and then docker-compose up, I can see the script runs, but something in it causes the container to fail and restart itself - the script then runs again, and the cycle continues. The docker-compose.yml has restart: unless-stopped specified by the way.
I wondered if one of the commands was exiting with a non zero code, so tried to add exit 0 to the end of the script, but to no avail.
Am I doing something daft? To be clear, I want this script to run automatically on the first boot of the container (it's fine if it runs every boot for what it's worth, not just the very first time).
