NUWE-Zurich-Cloud-Hackathon

This repository contains my entry for the on-site phase of the NUWE x Zurich Cloud Challenge.

Solution description

Terraform has been utilized to define a VPC, a subnet located in the VPC, two EC2 instances in the subnet together with their security groups and a S3 bucket.

Terraform's 'file' provisioner has been used to inject python application code into the EC2 instances using ssh the respective ssh keys.

EC2 instances' user_data has been set to run the flask server.

Inside the app repo Jenkins pipeline has been defined with Jenkinsfile - this pipeline runs terraform apply thorugh 'tfswitch'.

How to run and test the solution

Prerequisites

Run auto-install.sh to install all the necessary dependencies.

./auto-install.sh

Running the containers

Run docker-compose up from the root directory of the project.

docker-compose up --build -d

Install the Gogs server:

• go to http://localhost:3000
• change database type to SQLite3
• keep other settings as default
• create a zurich user with password zurich
• go to Your Settings -> Applications -> Generate New Token -> copy the token
• run export GOGS_TOKEN=<YOUR_TOKEN>
• run ./add_gogs_repo.py to add gogs repository and push app code and .tf files

Install Jenkins and configure Jenkins:

• go to http://localhost:8000
• install with defaults values
• create a git pipeline, for url enter the gogs repo url (add_gogs_repo.py script outputs this url)
• In Jenkins, go to the project configuration of the project for which you want to run an automated build. In the 'Build Triggers' section, select 'Build when a change is pushed to GitHub
