No shame in testing out enterprise solutions. Best of luck in your endeavor.

Oh, I see that RHEL has officially dropped docker support. You can try installing from binaries, but you are definitely striking out on your own here.

I don’t mean to rake you over the coals here, but what is the reasoning for sticking with RHEL for this project? If you are attempting to use it in an paid enterprise situation, you are better off sticking with items on the compatibility list. If you run into issues with other supported services, the first piece of advice will be to remove docker. Since your are not getting support for docker, I would advise running it from a supported OS.
