Continuous integration training for Epitech

• Log into your cloud9 development environment

1-Dockerfile creation

Create a Dockerfile for the app located in server.js

• The listening port is 80
• The main script is server.js

2-Dockerfile build

Build this dockerfile

• The name of the built image must be login/epitech-ci-training

3-Launching the image as a container

Instanciate the image

• This container must be started as a daemon

4-Changing the way of starting the container

server.js became app.js

• build the dockerfile in the entrypoint directory
• You are not allowed to create or edit the Dockerfile
• Launch the image to test if it's working

hint 1: entrypoint and cmd

hint 2: the OPS that created the Dockerfile could have made mistakes

5-Push the image to your personal account on dockerhub

Figure it out

6-By using Jest write integration tests for each route of the app.js file

https://www.npmjs.com/package/jest https://www.npmjs.com/package/supertest Sample unit and integration tests can be found in the tests folder

6.5-Compose

Theory: docker-compose

Edit the docker-compose.yml file located in the docker-compose directory in order to make it build our app

https://docs.docker.com/compose/compose-file/

6.6-Data access

Use the mysql package to create a connection to mysql in a new method contained in your app Write a jest test for this method https://www.npmjs.com/package/mysql#introduction

7-Let's create our pipelines of CI together

Theory: CPHP presentation

the trainer will create a public repository for our class

the trainer will assist you in the creation of your personal pipeline

create a script, ran into a test activity, that will build your app and execute the unit tests

remember we are already inside our container

8-Let's collaborate ! (and collide)

Theory: Git flow

The trainer will create the branch and restrictions needed for your git flow usage

Random tasks will be assigned to you

9-Integration testing

Theory: Integration testing

The trainer will add a mysql container to your pipeline

Create a simple bash script, connecting to this mysql container after the execution of your unit tests
