I was trying to use docker for my flask backend. I've written a docker file that uses python:3.8 as build-python then install all packages from requirements.txt file. I was PostgreSQL database then written in docker-compose.yml file. When I put command in terminal
sudo docker-compose run
It shows api_1 | Running on http://127.0.0.1:5000/ (Press CTRL+C to quit) which looks good. But I can't access this from my host pc It shows This site can’t be reached
Here is my docker-compose.yml file
version: "2"
services:
api:
ports:
- 5000:5000
build:
context: ./mymeds
dockerfile: ./Dockerfile
restart: unless-stopped
networks:

depends_on:
- db
volumes:
- ./mymeds/app/:/app/app:Z
command: python manage.py run
env_file: common.env
db:
image: library/postgres:11.1-alpine
ports:

restart: unless-stopped
networks:
