FastAPI Deployment with Docker on CentOS 7

Mar 15, 2024
FastAPI deployment with Docker on CentOS 7, including updating system, installing Docker and Docker Compose, configuring Nginx as a reverse proxy.
Firstly, you will need to update your system's default applications to their latest versions:
sudo yum update -y
Next, install the necessary utilities for Docker:
sudo yum install -y yum-utils device-mapper-persistent-data lvm2 sudo yum-config-manager --add-repo sudo yum install -y docker-ce sudo systemctl start docker && sudo systemctl enable docker
You'll also need to install Docker Compose:
sudo curl -L "$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose sudo chmod +x /usr/local/bin/docker-compose
Create a Dockerfile that will specify how your application should be built:
FROM python:3.10 WORKDIR /app COPY requirements.txt . RUN pip install -r requirements.txt COPY . . CMD ["uvicorn", "main:app", "--host", "", "--port", "80"]
Then, create a docker-compose.yml file to define your services:
version: '3' services: app: build: . ports: - "8081:80" volumes: - .:/app
After that, install Nginx, which will act as a reverse proxy for your application:
sudo yum install -y epel-release sudo yum install -y nginx
You'll need to configure Nginx to proxy requests to your FastAPI application. To do this, create a new configuration file in the /etc/nginx/conf.d directory. Use the command vim /etc/nginx/conf.d/ to open the file:
server { listen 80; server_name; location / { proxy_pass http://localhost:8081; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } }
Finally, start your Docker services and enable Nginx:
sudo docker-compose up -d sudo systemctl start nginx sudo systemctl enable nginx
And that's it!
