Hi,
Which fcos image you are using ? It looks like you are using fcos 34. Which is currently not supported. Use fcos 33.

Hi All, I was able to login to the instance. I see that kubelet service is in activating state. When I checked the journalctl, found the below.

Executed the below command to fix this issue. mkdir -p /sys/fs/cgroup/systemd
Now I am getiing the below error. Has anybody seen this issue.

Hi Ammad, Thanks for responding.
Yes the instance is getting created, but i am unable to login though i have generated the keypair. There is no default password for this image to login via console.

Hi, Can you check if the master server is deployed as a nova instance ? if yes, then login to the instance and check cloud-init and heat agent logs to see the errors.
