[BUG] Following instructions for podman install; "Only supported with OpenShift bundles"

[ianw]

General information

• OS: Linux CentOS 9-stream
• Hypervisor: KVM
• Did you run crc setup before starting it (Yes/No)?
• Running CRC on: VM

CRC version

CRC version: 2.7.1+a8e9854
OpenShift version: 4.11.0-0.okd-2022-07-29-154152
Podman version: 4.1.1

Steps to reproduce

I have followed the instructions at

https://access.redhat.com/documentation/en-us/red_hat_openshift_local/2.5/html/getting_started_guide/using_gsg#accessing-the-openshift-cluster-with-oc_gsg

Running crc os-env gives Only supported with OpenShift bundles and the oc tool is not installed.

I am clearly missing something about what the podman preset does? I thought that this would setup the openshift containers with podman giving me a small development environment. There's no containers running and I'm not sure what it's purpose actually is?

Is there any documentation I am missing about what the "podman" presets actually do?

I'm looking to translate some CI jobs from CentOS 7 era OpenShift 3 that used PaaS repos and a bunch of origin docker images [1]. The VM's we test in are "only" 8gb, so I can't even get crc started with the openshift backend. Another complication is that we are testing on a VM, and some of them don't supported nested KVM. Is it even possible to really start OpenShift 4 in this environment, or am I tilting at windmills?

The podman preset provides a Podman runtime it doesn't deploy OpenShift 4 using containers on the host, the podman preset is mostly useful for macOS and windows to have a container runtime available

The minimum requirements for running OCP are mentioned in the docs, https://crc.dev/crc/#_for_openshift_container_platform you need at leas 9gb ram

Perhaps a microshift option would be more suited for this, but this is currently on hold due to the rebase they are performing. We will be looking into this soon

However 8GB would not suffice for running OpenShift 4.x as our default is really the bare minimum without an application running.
