Flask Gunicorn Nginx Docker

Before, we have a manual config approach to deploy Flask app on server, as talked in THIS POST.
Now we use Docker to deploy the Flask app.

Gunicorn

Create a file gunicorn.conf.py:

bind = "0.0.0.0:8080"
workers = 4

Dockerfile

FROM python:3

WORKDIR /src

COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt

COPY . .

ENTRYPOINT ["gunicorn", "--config", "/src/gunicorn.conf.py", "jav:app"]

Nginx

vim /etc/nginx/nginx.conf

http {
	server {
		listen 80;
		server_name www.404909.xyz 404909.xyz;

		error_page 497 https://$server_name$request_uri;
		location / {
			proxy_pass http://127.0.0.1:4000;
			proxy_set_header Host $host;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		}
	}
    ......
}

Dockerhub

Config an auto build task in dockerhub account, then dockerhub will build image with every push in your Github.

Run

sudo docker pull mjyang/goldenshark
sudo docker image ls
sudo docker ps -a
sudo docker stop CONTAINER_ID
sudo docker rm CONTAINER_ID
sudo docker image rm IMAGE_ID
sudo docker run -p 4000:8080 -d mjyang/goldenshark
-p means port mapping, local prot : docker port
-d means background running
