# DevOps-Homework

## INTRODUCTION

DevOps Homework by 3yourmind for testing purposes. Contains all the Dockerfile(s) for Front-end, Back-end, Reverse Proxy. Moreover it also contains Ansible playbook for configuration and deployment of VM, and docker-compose.yml file for the deployment of docker infrastructure containing front-end, backend and reverse proxy as a load balancer.

## FRONT END

Front end folder in the repositry contains the docker file to create a docker image consisting of Vue.js real world example deployed in the image, once the container will be started, it will server front-end at certain port. This image is being setup using ubuntu:16.04 official docker image from dockerhub.

```

https://localhost:80/

```

## BACK END

Back end folder in the repositry contains the docker file to create a docker image consisting of Django real world example deployed in the image, once the container will be started, it will server back-end at certain port. This image is being setup using ubuntu:16.04 official docker image from dockerhub.

```

localhost:1871/

```

## ANSIBLE PLAYBOOK

Anisble playbook contains two roles, one is initial-server-setup and the other is vm-setup, first of all, to setup the base server on which KVM is to be installed is setup, dependencies and other packages are being installed and configured.

Secondly the role vm-setup is executed, using which the centos 7 KVM machine is deployed on the base server, which contains all the neccessary packages and dependecies to run docker, docker-compose and other things.

To execute the playbook one must have ansible installed.

```

ansible-playbook DevOps-Homework/ansible-playbook/playbook.yml --extra-vars "host=XYZ"

```

## REVERSE PROXY (nginx)

In reverse proxy setup, self signed certificate are being generated using openssl. moreover in our case nginx is serving as reverse proxy for the infrastructure.

## DOCKER INFRA-STRUCTURE

Docker-compose.yml, contains all the steps to setup front-end, back-end, reverse proxy using nginx, and postgre DB.

once the docker-compose file is up, it completely setup the whole infrastructure.

```

docker-compose --build

docker-compose up -d postgresql

docker-compose up -d 

```

## STEPS TO BE TAKEN

1) First of all ansible playbook is to be executed on the node to setup docker, docker-compose and other dependencies on node machine which is supposed to be a centos 7 machine.

2) Secondly steps mentioned in docker infrastructure part will be executed using the commands to make the infra up and working. It will build front-end, back-end, postgresql db and reverse proxy docker images and then bring up the containers.
