Hello,

after created a cluster Kubernetes environment and added 3 nodes, the container “Kubernetes\_controller-manager” not starts properly and shows me the next errors:

Could you provide more details of your setup?

What Rancher version? What docker version? What are the images being used for your kubernetes set up?

Ok, I recreated the environment and now it’s working fine. Maybe I miss some step before.

Thanks for your help-
