Fig is a fast, isolated development environments using Docker. For some features, it can be compared to Vagrant where the Dockerfike is not enough powerful to build multiple instances. For example, let’s say you want to test a new product version of a software like MediaWiki and you want to build the complete stack. So you may need to have several tools categories (depending of the usage): Web: Nginx, PHP-FPM, Varnish App Cahing: Redis Search: ElasticSearch In Vagrant you can natively build 3 VM and interconnect them without the need of additional tool.
