DevOps Interview Test

Welcome to Qwilt

In this repository you'll find Light-weight continuous deployment exercise.

General Guide-Lines

• Your work and configuration should be visible and you will be instructed to present them.
• We expect a running "Dummy" service, and a working automated deployment work-flow.
• Use this repository as the workspace for everything you build and configure

Let's Begin

1. You will do the exercise on EC2 machine , please download devops-candidate.pem and login to EC2 by:

ssh  -i <devops-candidate.pem full path> [email protected]

2. Clone this repository https://github.com/adiCohenIL/devops-chk on EC2

   Make sure you create your own branch to work on !

3. This repostitory contains dummy nodeJS app in CICD-exercise directory (See package.json and app.js)

Dummy Service setup

• cd CICD-exercise
• Install Node dependencies with: npm install
• Run service: npm run start

Dummy service has health check:

• GET http://localhost:3000/health - ⚠️ Randomly reports unhealthy!

4. Create a Dockerfile for the Dummy service for being able to run the service as a Docker container.
5. Docker registry is available on EC2 , called qwilt-registry

Get images in registry

curl -X GET http://qwilt-registry:5000/v2/_catalog

Get tags of image in registry

curl -X GET http://qwilt-registry:5000/v2/<image-name>/tags/list

6. Jenkins is available on http://54.75.84.188:8080 Edit "Ci Cycle" job, job should create and upload Dummy service docker image to registry

   Note: versioning of image is expected

   build groovy file should be saved in /home/ubuntu/repos/devops-chk/CICD-exercise/ci_jenkinsfile

7. Add Jenkins task to deploy dummy service container to EC2 machine ( get image from registry and run it)

8. Bonus: Add health check to your service (in the dockerfile)

Good Luck
