I am running flask application with nginx and Gunicorn, I am getting below error:
[root@master nginx]# curl http://127.0.0.1
curl: (7) Failed connect to 127.0.0.1:80; Connection refused
[root@master nginx]# curl http://127.0.0.1:80
curl: (7) Failed connect to 127.0.0.1:80; Connection refused
[root@master nginx]# curl http://127.0.0.1:8080
curl: (56) Recv failure: Connection reset by peer
Note: For some reason I should not use docker compose. Everywhere examples with docker compose only, not sure multi container can be achieved without docker compose.
I can directly access Flask api endpoint
[root@master nginx]# curl http://127.0.0.1:5000
Hello, World![root@master nginx]#
I am running Flask api docker image like below:
docker run -d -p 8080:80 nginx-frontend
I am running nginx like below:
docker run -d -p 8080:80 nginx-frontend
Both nginx and flask are running in same host and nginx.conf is below and i guess i am doing something wrong here
worker_processes 3;
events { }
http {
keepalive_timeout 360s;
server {
listen 80;
server_name 127.0.0.1;
charset utf-8;
location / {
proxy_pass http://127.0.0.1:5000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
}
Nginx docker file:
FROM nginx:1.15.2
RUN rm /etc/nginx/nginx.conf
COPY nginx.conf /etc/nginx
Python Flask Docker file:
FROM python:3.8-slim
RUN mkdir /app
WORKDIR /app
ADD requirements.txt /app
RUN pip3 install -r requirements.txt
ADD . /app
RUN chmod +x ./entrypoint.sh
EXPOSE 5000:5000
ENTRYPOINT ["sh", "entrypoint.sh"]
app.py
from flask import Flask
app = Flask(__name__)
app.config['DEBUG'] = True
@app.route("/")
def hello_world():
return "Hello, World!"
if __name__ == "__main__":
app.run(host='0.0.0.0')
