Uwe,
I do think my response is applicable. I'm sorry you feel differently.
To use podman generate kube and podman play kube, you don't need to
know any kubernetes. Podman generate simply takes your container or
pod and "records" it in kube yaml; and podman play simply replays it
the way it was recorded. You don't need to have any kubernetes
knowledge.
That said, you are correct that it is a different workflow and does not
cover all container and pod abilities. We are always trying to close
the gap there.
I wish you the best of luck!

Hi Brent,
do you really think, that your article is an appropriate answer to
the
initial question? I suppose not.
Surely you've mad a good job for people which are familiar with
Kubernets. For beginners like Robert and me, it's some kind of
chinese.
Just try to imaging:
- you are relatively new in the area of containers.
- you have heard just enough about Kubernets, to realize that it's
out
of scope for your needs.
- you have read about Kubernet's 'kompose' and have seen your
article.
A beginner like me, may think, "Ok, sounds reasonable".
But this leads into an dead end. 'kompose' creates a lot of nice
detailed configuration files, but none of them seems to be suitable
for
podman...
Without any experience or deeper knowledge about Kubernet, I
resigned.
Uwe
PS.
Maybe, you could write a detailed howto for the new podman pages.
