HN folks seem to prefer Podman instead of Docker.

To the degree that's true, the preferences of HN folks probably isn't the best North Star for a career...it encourages the expression of contrarian opinions for the sake of expressing contrarian opinions and by design, HN fosters an endless september.

Out in the real world, Docker has better brand recognition and though there are arguments for Podman, who wants to have an argument? Sure some people want that, but it might not be a good substitute for getting paid.

Finally, no amount of study is going to bring the expertise that comes with a bit of on-the-job experience. So if you are going to study one, study the one that is most likely to be used on the job. And the one most likely to get you a job.

Compare:

  I don't know Podman, but I know a little Docker.

  I don't know Docker, but I know a little Podman.

Which would be better in an interview?

Good luck.
