Using Docker for Sculpin

[beryllium]

This issue is intended to be a discussion point for how we can use Docker with Sculpin.

Primary concerns:

• Delivering a stable experience for users
• Handling complex site configurations, including possible multi-site configurations
• handling complex installations, with required PHP extensions & custom sculpin kernel & many composer deps

My hope is that all of this could be solved with a very short Dockerfile that people can easily put in their projects. Ideally, with minimal required maintenance for both users & project maintainers.

I just tried to dockerize Sculpin via the new semi-official "PHP-way" to dockerize apps:

composer create-project sculpin/blog-skeleton my-blog
cd my-blog
yarn install
composer sculpin-watch

Then run:

ln -s source public
composer require --dev phpexperts/dockerize
php vendor/phpexperts/dockerize/install.php
docker-compose up -d

Worked like a champ.

It literally took me less than 2 minutes to dockerize this app. I've been using phpexperts/dockerize on all of my projects. All you really have to do is ln -s your_web_root public and you're good to go! Maybe edit a few nginx rewrite rules in the provided docker/web/sites/001_default.conf. Works well with Kubernetes, too.

Of course, following the documentation on https://github.com/PHPExpertsInc/dockerize-php, I edited the the newly-created docker/web/sites/001_default.conf and disabled the listening to the PHP-FPM proxy for a pure static site.
