Is there a way to install system packages in the dockerize step?

[brspurri]

I need to have my workflow reference a system command that is installed via apt-get install .... Is there a way to allow the dockerize step to build a custom docker image?

Or another option that would work in my case would be to have the base image be something else. Not sure if this is possible either.

Yes! First, sorry, I'm so late getting to this. Please feel free to ping me at [email protected] if I don't get back sooner. You can list files in a standard deb.txt file. You create a "config" directory, and place the deb.txt file within it. Then run the dockerizer via dsdt dockerize --config-dir <your dir>. There is also support for installing r packages.
