Deploy FASTAPI on AWS EC2

Launch an EC2 Instance

After register an AWS account, go to Console Home and click to EC2 Dashboard. Config an EC2 Instance as following:

Name
Machine Image: Ubuntu (Latest long term supported version)
Instance Type: t2.micro

Create a Key pair to login by ssh

Key pair name
Key pair type: RSA
Private key format: .pem

Once you've created a key, you will see a key downloaded.

Network Settings

Allow ssh traffic form: anywhere
Allow http access from the internet
Allow https access from the internet

Launch instance! Go back to the EC2 dashboard and you will see your instance is running like:

Information like public IP can be viewed:

Connect to the instance

chomd 400 [name].pem

Then just copy the ssh command.Remember you need to go to the directory where your pem file stored before paste the SSH command on your terminal. You will see this after login:

Server settings

sudo apt install -y python3-pip nginx

Create configuration file:

sudo vim /etc/nginx/sites-enabled/fastapi_nginx

server {
    listen 80;   
    server_name 18.116.199.161;    
    location / {        
        proxy_pass http://127.0.0.1:8000;    
    }
}

sudo service nginx restart

Then clone your FASTAPI project to your server.

Install all the dependencies and packages by:

pip3 install -r requirement.txt

Start the FASTAPI

python3 -m uvicorn --host 0.0.0.0  main:app

Increase EC2 storage

I found the 8 GiB is not enough for my project so I decided to upgrade the storage.

Click on EC2 instance and then go to the storage session
Then modify the volume:
So far we have increase the size of EC2, we need to cofig our server by ssh login
List block devices, svda1 is your original hard drive
```
lsblk
```
Increase our partition
```
sudo growpart /dev/xvda 1
```
You can see the volume increse by lsblk
Extend our file system
```
sudo resize2fs /dev/xvda1
```
You should see the volume got extend

Security Setting

If new port needed (default 80), you may consider to add a rule:

TCP [port] 0.0.0.0/0(all ports)

Test connection

netcat [ip address] [port]
curl http://[ip address]:[port]

A common problem is the Chorme may automatically set http->https, whcih may result in Invalid HTTP request received. One way to solve this is to deploy the frontend to the server as well.

Another problem may encounter is Mixed Content: This request has been blocked; the content must be servered over HTTPS. You can add

<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">

at the haed part of your public/index.html of your React front-end.
