anyway to get it fixed?

Hi @mallilinux1980, sorry for the late response. I'm afraid that you're not running the scenario as suggested in the documentation, infact you're trying to mount the yaml config file as a volume instead of exposing the requested parameters as environment variables. I've just tested the scenario with this syntax: podman run --name=pvc --net=host --env-host=true -v $(pwd)/kubeconfig:/home/krkn/.kube/config:Z -e POD_NAME=elasticsearch-master-0 -e NAMESPACE=default -e FILL_PERCENTAGE=65 -e DURATION=60 quay.io/krkn-chaos/krkn-hub:pvc-scenarios and works perfectly fine!

Please let us know if you have further questions or issues running krkn-hub scenario, you can also reach out directly on slack https://kubernetes.slack.com, #krkn channel.

re-tried but same error. $ podman run --name=disk --net=host --env-host=true -v /tmp/.kube/kubeconfig-42:/home/krkn/.kube/config -e POD_NAME=virt-launcher-d12472-064 -e NAMESPACE=virtualmachines -e FILL_PERCENTAGE=65 -e DURATION=60 quay.io/krkn-chaos/krkn-hub:pvc-scenarios

[tsebastiani]

did you try to clear your local image cache (just in case)?

[mallilinux1980]

yes but no luck.
