Composer plugin for auto-generating platform requirements in composer.json.

The plugin generates config.platform section in composer.json file basing on current PHP environment. This is especially useful when Docker images are used. Once generated config.platform section in runtime image may correctly reused in toolchain images (such as composer Docker image).

Usage

composer global require "instrumentisto/composer-platform-generator"

cd my-project/
composer update-platform-reqs

in-Docker

cd my-project/

# Vendor and install necessary dev dependencies.
docker run --rm -v "$(pwd)":/app -w /app \
  composer require --dev "composer/composer" \
                         "instrumentisto/composer-platform-generator"
docker run --rm -v "$(pwd)":/app -w /app \
  composer install --ignore-platform-reqs

# Generate config.platform section basing on you runtime image.
docker run --rm -v "$(pwd)":/app -w /app \
  my-project-image \
    vendor/bin/composer update-platform-reqs

# Now you can run the commands bellow without errors
# and with PHP environment considered exactly as you need.
docker run --rm -v "$(pwd)":/app -w /app \
  composer install
docker run --rm -v "$(pwd)":/app -w /app \
  composer update
