How to start redis server inside docker container

Question

FROM python:3.6

ENV PYTHONUNBUFFERED 1
WORKDIR /usr/src/consumerhub

COPY ./ /usr/src/consumerhub


RUN curl -sL https://deb.nodesource.com/setup_11.x | bash -
RUN apt-get install -y nodejs

RUN apt-get install -y redis-server
RUN systemctl start redis

RUN pip install -r requirements.txt
RUN npm install --prefix frontend/


CMD ["/bin/bash","-c","python manage.py runserver react 0.0.0.0:8000"]

I am using redis in docker container.

I am using "systemctl start redis" to start redis inside container. It is saying systemctl is not a command.

Note: I don't wants to use docker-compose i have to do it here.

Please have a look

Here you go. You do not need to start anything after container up. Everything will be starting on bootup. And one thing I tested using Alpine, instead of python ubuntu which is heavy as compared to alpine.

Modify commented thing for your python app

FROM python:3.6-alpine
RUN mkdir -p /etc/supervisord.d

# general config for supervisord

RUN echo  $'[supervisord] \n\
[unix_http_server] \n\
file = /tmp/supervisor.sock \n\
chmod = 0777 \n\
chown= nobody:nogroup \n\
[supervisord] \n\
logfile = /tmp/supervisord.log \n\

logfile_backups=10 \n\
loglevel = info \n\
