[SOLVED] docker - using python image, add the non-free Debian repo?

Issue

Im using a python image in docker and have added some dependencies as per the below:

RUN apt-get update -y \
    && apt-get install -y apt-utils libsasl2-dev python3-dev libldap2-dev libssl-dev libsnmp-dev snmp-mibs-downloader

I'm getting an error

E: Package 'snmp-mibs-downloader' has no installation candidate

Which after searching is because I need a non-free repo adding as per: http://installion.co.uk/debian/wheezy/non-free/s/snmp-mibs-downloader/install/index.html

I believe I need to edit /etc/apt/sources.list and add the below:

deb http://http.us.debian.org/debian jessie main contrib non-free
deb http://security.debian.org jessie/updates main contrib non-free

but how do I do that via a docker file?

Solution

The same way you would do to add the non-free component to your sources.list. Edit the /etc/apt/sources.list file in your Dockerfile and replace the line that looks like:

deb http://http.us.debian.org/debian jessie main contrib

by

deb http://http.us.debian.org/debian jessie main contrib non-free

You can do that in the Dockerfile with a command like

sed -i "s#deb http://http.us.debian.org/debian jessie main contrib non-free#deb http://http.us.debian.org/debian jessie main contrib non-free#g" /etc/apt/sources.list

And same for security.debian.org.
