We have standardized on RHEL 8.3 and are trying to NOT use Docker. I have downloaded the latest and greatest Podman rather than use the RH repos.
Q1: Will Kubernetes work with Podman? I seem to be in the minority and have not found many comments about this combination.
Q2: Anyone seen any good installation guides? The answer to Q1 may be that fact that I am not installing things properly. I’m starting from a base generic install on a new system. Most of the guides I have seen make lots of assumptions of what is already installed.
I have a task that Kube would be perfectly suited for but I can’t get it working, BTW: Podman works perfectly.
You can use podman, but it requires something like CRI-O to work as an intermediary. RedHat uses it for openshift, but to the best of my knowledge - they’re really the only ones actively using it. containerd is generally the preferred choice by most folk.
I do not - My apologies, I meant in my previous post that I don’t really know anyone using podman. Most folk use containerd and runc behind the scenes (containerd’s default)
I have primarily the same questions - and not much of an answer so far - but just to let you know you are not alone in this
I have been using podman as a replacement to docker for a whole year now in a production environment and have come to like it much more than docker; I am rather surprised too that podman is not more often mentioned in the kubernetes docs
So I’m currently trying to achieve goals that are similar to yours iiuc, i.e. set up a playground k8s cluster on a handful of bare metal nodes running f33; I’m trying to use as little as I can from outside of the mainstream fedora + kubernetes repos
my working angle for now is to bet on a cri-o / podman combination, I’ll see how it goes
PS. I have considered using openshift but that is clearly something I am not going to be able to afford, so here I am
if there’s interest I can report on this thread about my findings
I too like podman better and have already started using it for semi-production.
However, I have had to make some tough choices. Red Hat really did a number on version 8.3 for Docker. I could not get Podman and Kubernetes to work on RHEL. Docker on RHEL 8.3 is severely crippled and will not work with Kube… I finally switched to Ubuntu 18 and got Kube working with Docker the first day.
