@olberger Seems like there was an issue with kata-deploy. cri-o does not seem to be installed for some reason. You are doing this on the vagrant setup correct?
I was able to bring it up and curl the endpoint

Uh @krsna1729, I'm not sure... I'm following the instructions using create_stack.sh... and saw no traces of kata-deploy :-/
kubectl logs -n kube-system kata-deploy-kxdff won't return anything then...

@olberger substitute without your pod name or else try this
clear@clr-01 ~ $ kubectl logs -n kube-system -l name=kata-deploy

also use ./create_stack.sh minimal. You wont need the extra stuff for this test
from cloud-native-setup.

Hi.
Just did a create_stack.sh minimal again, and here's the output of :
clear@clr-01 ~/clr-k8s-examples $ kubectl logs -n kube-system -l name=kata-deploy

Not sure why crio folder does not exist. setup_system.sh must have set everything up

@olberger umm this is so weird. @ganeshmaharaj any ideas
from cloud-native-setup.

commented on July 24, 2024
I think I nailed it : I had no nested KVM virtualization activated... which probably made the crio installation/restart fail.

commented on July 24, 2024
@olberger did you get it to work? I still do not understand why crio.conf is missing. it is independent of virtualization

@olberger Are you still encountering this problem?

The conf file does not exist after installing on a recent version of Clear with
sudo -E swupd bundle-add --quiet cloud-native-basic storage-utils
There is no /etc/crio directory or conf file there but it does exist at /usr/share/defaults/crio/crio.conf
from cloud-native-setup.

commented on July 24, 2024
I thought our system_setup was copying the file over by default to /etc/crio. Also i thought crio would work by looking at /usr/share/defaults too based on https://github.com/clearlinux-pkgs/cri-o/blob/master/0001-include-usr-share-defaults-in-conf-file-search.patch Is that no longer the case?

Clear's kata-runtime package installs crio-set-runtime.service which is run upon crio.service restart. The conf file is created by crio-set-runtime if /dev/kvm exists.

@olberger closing this as obsolete (file exists now). Please re-open if the issue persists for you.
