How to run background applications using Docker?

Question

I’m trying to run my Python application inside a container, only I need to install a proxy dependency that I use: Luminati, the problem is that apparently luminati is not running in the background after I initialize the container.

I tried to run it this way:

docker run -it test_app:latest

When rotating a ps ax luminati application is not rotating!

Docker-Compose.yml

version: '3'

services:
  app:
    build: .
    volumes:
      - .:/shared
    networks:
      - vnet-front

networks:
   vnet-front:
     driver: bridge

Dockerfile

FROM python:3.6-alpine AS build-ev

RUN apk add nodejs
RUN apk add npm
RUN npm install -g @luminati-io/luminati-proxy --unsafe-perm
RUN mkdir /app
WORKDIR /app
COPY . /app
RUN luminati --config luminati.json
ENTRYPOINT ["python", "test.py"]

Answer 1

So you can start your application at the time the container is called, rather than using the RUN you use the CMD:

Dockerfile altered:

FROM python:3.6-alpine AS build-ev

RUN apk add nodejs
RUN apk add npm
RUN npm install -g @luminati-io/luminati-proxy --unsafe-perm
RUN mkdir /app
WORKDIR /app
COPY . /app

CMD luminati --config luminati.json && python test.py

So, at the moment startar your image (something like):

docker run -d -p 22999:80 test_app:latest

The application (luminati) will be executed and your test.py also.
