install app with composer

[mjeandon]

Helo. I want to annoy you again
I want to install msmtp in the container and with composer, mpdf and simple_html_dom
For msmtp, no problem, but with composer, the system installs but doesn't appear in "app\vendor" or in "composer.json".

My Dockerfile:
FROM shinsenter/codeigniter4:latest
RUN apt-get update &&
apt-get install -y msmtp ca-certificates &&
rm -rf /var/lib/apt/lists/*

Copier la configuration msmtp

COPY msmtprc /etc/msmtprc

Définir les permissions pour le fichier de configuration

RUN chmod 600 /etc/msmtprc
RUN composer require voku/simple_html_dom
RUN composer require mpdf/mpdf

the log build:
..........
#10 [6/7] RUN composer require voku/simple_html_dom
#10 3.608 ./composer.json has been created
#10 3.621 Running composer update voku/simple_html_dom
#10 3.623 Loading composer repositories with package information
#10 6.892 Updating dependencies
............
How I can do?

Hello @mjeandon

Just to clarify - the Docker images I provide do not include any framework source code. They only serve as runtime environments for PHP code and necessary extensions to run the framework.

If you want to install packages using Composer, please make sure you've copied your project’s source code (including the composer.json file) into the web root directory inside the container before running composer install to proceed with the package installation.

For example:

FROM shinsenter/codeigniter4:latest

### Copy your project’s source code (E.g in ./src/) into the web root directory
COPY ./src/ $APP_PATH/

### Install Composer packages
RUN composer require mpdf/mpdf voku/simple_html_dom

### Install other middlewares (such as msmtp)
....

However, this approach may significantly increase the final size of the Docker images.

Another way is to pre-install the packages globally, so they won’t depend on your project’s composer.json settings. However, after copying your source code into the container’s web root, you’ll need to run composer dump-autoload once to update the autoload file for those packages.

For example:

FROM shinsenter/codeigniter4:latest

### Global installation of Composer packages
RUN composer global require mpdf/mpdf voku/simple_html_dom

### Copy your project’s source code (E.g in ./src/) into the web root directory
COPY ./src/ $APP_PATH/
RUN  composer dump-autoload 

### Install other middlewares (such as msmtp)
....

All the points I mentioned above are related to using the Composer command. I’d really appreciate it if you could take some time to go through Composer’s FAQs.

Best regards

Thank you.
