Assigning my docker an ip on a custom docker network

[lovingHDTV]

this is my first attempt at creating a docker container and running it on UnRaid.

 

I create my container using docker build.  I then try to run it with:

 

docker run --name heatmaster --ip='192.168.20.246' -d heatmaster

 

It runs, but I don't get assigned that ip address. I can get a console into it as well, but the IP address is a 127... address, not the one I assigned.

 

How do I got about assigning an ip address to the container?  I got my command line by looking at an UnRaid container when it started up.

 

thanks

Ok I figured out that I need to at least do:

docker run --net br0.10 --name heatmaster --ip='192.168.10.246' -p="5000" -d hello-world

 

This does create it so that I can see in the Docker page the correct IP address:port.  It looks just like the others.

 

However, when I try to go to the port I get a permission denied message.

 

If I get a console, I can access at 127.0.0.1:5000 just fine.

 

Here is my container:

FROM ubuntu

RUN apt-get update
RUN apt-get -y install python3
RUN apt-get -y install python3-pip
RUN apt-get -y install curl
RUN pip install flask
RUN pip install playwright

ADD app.py /
ADD heatmaster.py /
WORKDIR /

USER nobody

EXPOSE 5000

CMD ["python3","app.py"]

 

Do I have to something on the CMD line to say to run on port 5000?
