I'm just getting into Docker, so please excuse my noobiness.
I've set up a Dockerfile for a unit testing project, based on the guidelines in this article. The container runs fine, and I managed to run the tests. But I got different results in my local container than we got on our build bot. So I thought it might be because the build bot is on Ubuntu, while my local container appears to be Debian.
So, how do I set up the Dockerfile to use Ubuntu rather than Debian?
COPY ./bin/Debug/netcoreapp2.1/linux-x64/publish/ .
ENTRYPOINT ["tail", "-f", "/dev/null"]
