No, it is not impossible to generate a composer.lock file within a Docker container. However, it depends on whether the dependencies are already installed in the container, and whether the composer.json file is present. Here are steps to generate a composer.lock file within a Docker container:
FROM php:7.4-apache
RUN apt-get update \
&& apt-get install -y git unzip \
&& docker-php-ext-install pdo_mysql
COPY composer.json /var/www/html/
RUN cd /var/www/html/ \
&& php -r "readfile('https://getcomposer.org/installer');" | php \
&& php composer.phar install
This command will install the dependencies and generate the composer.lock file.
COPY . /var/www/html/
CMD ["apache2-foreground"]
Now, when you start the container, it will have the composer.lock file generated.
