I recently came across a message on the kubernetes discourse here
and I thought it would make sense to chime in here
in essence in that post we share our surprise to see so little reference
to podman in the k8s documentation
Podman is not meant to run K8s. Podman targets single-node machines and
focuses on servers and developer machines. It does not implement Container
Runtime Interface (CRI) that K8s uses to communicate with the container
runtime. CRI-O is dedicated to exactly that use-case.
However, Podman allows running K8s yaml via the `podman-play-kube`
command. The idea behind is to easily run and test K8s yaml without the
need of an entire cluster. That can come in handy for development but it's
also a portable bridge from a single-node environment or a workstation to
an orchestrated environment such as K8s. Yaml files can further be
generated via `podman-generate-kube`.
Brent wrote a great blog on that topic:
as a first step imho it would drastically help to at least know what
combinations of fedora/k8s/cri-o are expected to work properly
CRI-O's versioning follows the K8s versioning scheme. For instance, CRI-O
1.20 should run with K8s 1.20.
on my side I’ve just started playing with this combo:
* plain fedora33
* with its vanilla podman 3.1.2
* cri-o 1.20 - through
dnf module enable cri-o:1.20
dnf install cri-o
systemctl enable crio —now
* and minikube for now, that I trigger using this
minikube start --driver=podman --container-runtime=cri-o
which kind-of works, but this is very early stage, and I’m facing a few
glitches so I’d really like to find a place where I can share my findings
so, a rather open question as you can see :)
any insight, either general or specific, or pointer to a doc that we would
have overlooked, or clue on the right place to discuss all this, would be
very much appreciated
Can you elaborate on the issues you face?
If you see specific bugs, opening an issue upstream would be great. For
questions, the mailing list works well, GitHub issues or the #podman
channel on Freenode IRC (and Libera Chat).
