CONTAINERS

AN APPLICATION, PLUS ALL ITS DEPENDENCIES, LIBRARIES AND OTHER BINARIES, AND CONFIGURATION FILES NEEDED TO RUN IT, BUNDLED INTO ONE PACKAGE.

WHAT ARE CONTAINERS?

HOW?

CONTAINERISE YOUR STACK

1.INSTALL DOCKER (ONLY)

docker for mac / windows docker toolbox docker engine for linux

2.WRITE DOCKERFILE▸ configuration file with build instructions for

Docker images

3.WRITE COMPOSE ▸ Compose is a tool for defining and running

multi-container Docker applications

SIMPLE VOTING APP : APP UNDER TEST▸ Simple Real Time voting app

▸ Runs with Docker Compose and multiple containers in network

VOTING APP : COMPONENTS

Deliver below tests as container to test Voting app

1.API 2.Web 3.Web with Selenium Grid
