How to automatically start processes (tor, privoxy) in Docker with container start?

Question

Docker

Hello! I just recently started using docker, but I don’t understand how to start processes in a container. Here is my Dockerfile:

FROM ubuntu:16.04

RUN \
    apt update && apt install -y \
        tor \
        privoxy

FROM python:3
 
WORKDIR /usr/src/app
 
COPY requirements.txt ./

RUN pip3 install --no-cache-dir -r requirements.txt

I found this tutorial about launching tor and privoxy in the docker container console: https://gist.github.com/DusanMadar/8d11026b7ce0bce... The
question arose: is it possible to run these processes together with the launch of the container (in other words, just write to the dockerfile) rather than doing it manually in the console each time?
I tried to do this through
CMD service tor start or just
CMD tor, but when I start it, it gives an error that there is no such process.

Answer 1

Why do you want to run multiple services in the same container? Docker ideology: one process - one container. The task is to isolate tor and privoxy in separate containers, and then connect - over the network or shared directories.

1. Add to Dockerfile:
CMD /etc/init.d/tor start && sleep 5 && /etc/init.d/privoxy start
2. Or add to Dockerfile:
CMD /start.sh
and stuff everything you need into start.sh run/check
