如何在 php 容器中从 dockerfile 运行 composer install

Question

Good day I have php container which seting up in Dockerfile

I am trying to run composer install with this command

WORKDIR '/app'
RUN curl -sS https://getcomposer.org/installer | \
            php -- --install-dir=/usr/bin/ --filename=composer
        CMD bash -c "composer install && php artisan serve --host 0.0.0.0 --port 80"
    EXPOSE 80
    EXPOSE 22
    CMD ["php-fpm"]

But I didnt get the error, and can not run application because of the composer install didnt worked.Just white screen of laravel which mean composer was not installed.

If I run after docker compose up

docker run -it --rm -v $(pwd):/app composer/composer install

I receive an error Composer could not find a composer.json file in /app To initialize a project, please create a composer.json file as described in the https://getcomposer.org/ "Getting Started" section

If I trying to COPY project dirrectory I receive an error

COPY /var/www/docker/project /app

ERROR: Service 'php' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder091462376/var/www/docker/project: no such file or directory While I have the volumes in php container in docker-compose.yml

volumes:
            - ${APP_PATH_HOST}:${APP_PATH_CONTAINER}
            - /app/vendor/

It seems you are mixing PHP-FPM and a standalone PHP server. Rather move the artisan serve to the CMD. Also, you can only have one CMD , which is the command that needs to execute when the container starts. In order to execute other commands when building the container, you need to use the RUN command. So your Dockerfile can look like this:

WORKDIR '/app'
RUN curl -sS https://getcomposer.org/installer | \
            php -- --install-dir=/usr/bin/ --filename=composer

RUN "composer install"
EXPOSE 80
EXPOSE 22
CMD "php artisan serve --host 0.0.0.0 --port 80"
