Deployment Process

Create DNS record

- To create a DNS record, first log into [AWS](https://aws.amazon.com/ec2/)

- Account Details:
    - Account ID: nighthawkcodingsociety
    - IAM username: ubuntu
    - Password:  Ubuntu14*&*41


- Once signed in, click the button on the home page titled **Route 53**

- The next step (when on the Route 53 page) is to press the **Hosted zones** section on the column to the left.

- Here, click on the hosted zone called stu.nighthawkcodingsociety.com

- We have made it to the page where we can create a DNS record. Click the button that says Create record

- When creating a record, its necessary to put in some information. Here is the following information that should be inputted:
    
    - Record name: name of project (ex: cantella)
- Record type: A - Routes traffic to an IPv4 address and some AWS resources
- Value: 3.129.109.200
- TTL (seconds): 300
- Routing policy: Simple routing

- Once all categories have been filled, click the Create record button on the bottom right.

- If successful, a notification should pop up that a new record was successfully created

After this has been completed, you will have successfully created a DNS record.

AWS Setup

- First, login into the [AWS Terminal](https://cockpit.stu.nighthawkcodingsociety.com/system/terminal)

- Now run the following commands:
Change into the correct directory: cd ~
Clone backend repo: git clone https://github.com/Githubneos/scribble_backend.git
Navigate into repo: cd scribble_backend
Build the site: docker-compose up -d --build
Test site: curl localhost:8203

Nginx Setup

Change into the correct directory: cd ~
Navigate into repo: cd scribble_backend
Copy paste nginx file into /etc/nginx/sites-available: sudo cp scribble_nginx_file /etc/nginx/sites-available/.
Change back into ~ directory: cd ~
Navigate to sites-enabled: cd /etc/nginx/sites-enabled
Create a symbolic link (shortcut) to the nginx file in sites-available: sudo ln -s ../sites-available/scribble_nginx_file
Test to see if there is any syntax errors: sudo nginx -t
Restart nginx: sudo systemctl restart nginx
Test domain name on a browser (http:// only)

(4) Certbot Config

Run sudo certbot –nginx
