                Theory
                What do we need:
                
                    - docker environment
- source code + php + nginx
Prerequisites
                
                    - docker engine
- docker client
- docker-compose
Docker Compose

                ...we're one step closer...
                CI, testing, staging, prod etc.
            
            
                ...but there are some caveats
