HOW?
CONTAINERISE
YOUR STACK

20.
1.INSTALL DOCKER (ONLY)
docker for mac / windows
docker toolbox
docker engine for linux

21.
2.WRITE DOCKERFILE
▸ configuration file with build instructions for
Docker images

22.
3.WRITE COMPOSE
▸ Compose is a tool for defining and running
multi-container Docker applications

23.
SIMPLE VOTING APP : APP UNDER TEST
▸ Simple Real Time voting app
▸ Runs with Docker Compose and multiple
containers in network
