CloudCostCalculator

This project is a very basic Cloud Cost Calculator. AWS Pricing APIs are utilized to fetch various AWS product's information. User can create their whole AWS cloud inventory and can save it to pdf for organizational use etc. Also the user can generate price report, which gives approximate estimate of their AWS resource costs.

More importantly this project can be used as learning material if anyone wants to explore how to use AWS Javascript SDK and Angular. Currently only EC2, S3 and RDS services are considered. If anyone wants to extend the functionality then please fork and share the idea with me.

Demo

Development server

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files. (See configure)

Configure

In order to use this application you have to generate an IAM user (Programmatic access for API use) with AWSPriceListServiceFullAccess policy attached (more info here).

After generation of the user, you will get access key and a secret key which will be used to access AWS Price List API. Run the following command to inject those tokens in code:

$ ./add_creds.sh <access token> <secret token>

Note: Escape the special characters (precede char with \) while supplying the parameters in above command.

To clear those tokens from the code run ./add_creds.sh clear.

Build

Docker

$ # Build
$ docker build -t cloud-cost-calculator .
$ # Run
$ docker run -d -p 8080:80 cloud-cost-calculator

Static Deployment files

$ npm install
$ ng build --prod

This will produce ./dist/CloudCostCalculator directory which contains javascript bundles and all static files which can be hosted on server.

Ansible

This project contains ansible playbooks with roles (See readme files inside ansible/roles/rolename for more info) to create aws resources and to automatically deploy this application on created server instance.

Build & Configure

$ npm install
$ ng build --prod --output-path ansible/roles/app-server/files/CloudCostCalculator/

To run the ansible playbooks you will need to configure aws keys for ansible. So for that go to groupvars dir cd group_vars/all. Then create a vault (delete existing file) for your aws keys ansible-vault create aws_creds. Enter following in the vault file:

---
aws_access_key: <your access key>
aws_secret_key: <your secret key>

Then create a pass.txt and enter your password in that file OR you can use --ask-vault-pass while running your palybook.

Deploy

$ ansible-playbook site.yml

This will create your AWS resources (Public VPC, Subnet, IGW, EC2 instances) and also deploy the application on that instance.
