'PLAYKart' is an E-Commerce platform in India. It is one of the top e-commerce platforms across India
that specializes in handling high-availability and low latency in processing the order requests for
the customers.

The PLAYKart team came up with the new feature to overcome the latency & other issues, the team had
an idea of dockerizing the applications & deploy it in docker and K8s parallelly to check the efficiency.

So you are tasked to perform two modules, Module 1 is to dockerize the frontend & backend application
and deploy the same using Docker compose. Module 2 is to dockerize the other application and deploy it
using Kubernetes.

Note:
- Run the given 'setup.sh' file given in the path "~/Desktop/Project/slamdunk-itis-apr23-phase2" to
install the required dependencies before starting the challenge.

Getting started:
- A Full Stack application with 'Angular' frontend and 'Nodejs' backend is given in the path
"~/Desktop/Project/slamdunk-itis-apr23-phase2".
- A Flask application named 'application.py' is given in the path "~/Desktop/Project/slamdunk-itis-apr23-phase2/flask".

MODULE - 1:
-----------
1. Create a 'Dockerfile' to dockerize the 'Angular' application as 'frontend-img' using 'node:14' as
its base image in the path "~/Desktop/Project/slamdunk-itis-apr23-phase2/angular".

2. Create another 'Dockerfile' to dockerize 'Nodejs' application as 'backend-img' using 'node:14' as
its base image in the path "~/Desktop/Project/slamdunk-itis-apr23-phase2/nodejs".

3. Create a 'docker-compose.yml' file in the path "~/Desktop/Project/slamdunk-itis-apr23-phase2" to
create two services named 'frontend-service' and 'backend-service'.
- The 'frontend-service' should run the generated docker image of 'Angular' application as a container
named 'frontend-v1', expose to the port 8067, mount it to the volume named 'app_volume' and attach it
to the network 'app_network'.
- The 'backend-service' should run the generated docker image of 'nodejs' application as a container
named 'backend-v1', expose to the port 8001, mount it to the volume named 'app_volume' and attach it
to the network 'app_network'.
Note: Docker volume and network should be created in Ansible playbook as specified below.

4. Create an Ansible playbook named 'playbook.yml' in the path "~/Desktop/Project/slamdunk-itis-apr23-phase2"
which automates the deployment of the applications with the use of appropiate Ansible modules.
- Create a new Docker bridge network named 'app_network'.
- Create a new Docker volume named 'app_volume' mounted to the default Docker volume's directory.
- Run the 'docker-compose.yml' file to deploy the application.

5. Finally, run the playbook and check whether the Full Stack application has been deployed & exposed in the
specified port.

6. Ensure that the 'frontend-v1', 'backend-v1' containers are in running state before starting Module-2.
