Nginx Question posted in
The official documentation can be found here.

running script in Dockerfile makes Container Exit with Code 0, running the same script with docker exec works fine – Nginx

So Im building a Laravel application, I have a mysql db defined in my docker-compose.yml and an nginx webserver to go together with my php app.

this is the Dockerfile of the PHP app:

# Install dependencies
RUN apt-get update && apt-get install -y 
    build-essential 
    libpng-dev 
    libjpeg62-turbo-dev 
    libfreetype6-dev 
    locales 
    zip 
    jpegoptim optipng pngquant gifsicle 
    unzip 
    git 
    libonig-dev 
    libzip-dev 
    curl

# Clear cache
RUN apt-get clean && rm -rf /var/lib/apt/lists/*

# Install extensions
RUN docker-php-ext-install pdo_mysql zip exif pcntl gd mysqli pdo

WORKDIR /var/www

COPY composer.lock composer.json ./

# Install composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=comp>

# Copy existing application directory contents
COPY . ./

RUN chown -R www-data:www-data /var/www

#laravel + packages install
RUN composer install

RUN chmod -R guo+w storage

# Expose port 9000 and start php-fpm server
EXPOSE 9000

CMD ["php-fpm"]

ENTRYPOINT ["/var/www/migrate.sh"]

the shell script just is this:

#!/bin/sh

nohup php artisan migrate:fresh --force


golb_app_1 exited with code 0
app_1        | Dropped all tables successfully.
app_1        | Migration table created successfully.
app_1        | Migrating: 2014_10_12_000000_create_users_table

app_1        | Migrated:  2021_06_09_120221_update_users_table (21.67ms)
golb_app_1 exited with code 0

Is the output that I am getting If i run my docker-compose up.
Then Container will restart and do it again and again.

If I comment out the script and run it with docker exec It will run and the DB works fine.

    #!/bin/sh

php artisan migrate:fresh --force &

php-fpm

    call script where php-fpm is called now (CMD) delete Entrypoint

    "exited with code 0" means it run successfully. And since it’s the entrypoint, its expected for the container to stop.

    You need to run the serve command after migrate:

    php artisan serve --host=0.0.0.0 --port=$APP_PORT
