Can't install pip packages inside a docker container with Ubuntu

Question

I\'m following the fig guide to using docker with a python application, but when docker gets up to the command

RUN pip install -r requirements.txt
         


        

Answer 1

In case someone is reading this using docker-compose. I managed to resolve this by changing my yaml file as follows

version: 3.4
service: my-app
  build:
  context: .
  network: host

which is equivalent to writing

docker build . --network host
