Hi, Everyone, I've tried Magnum in Queen version with centos and the Problem is Kube-Master in stucked in creating in progress state???? The entire process like one master instance will be created with floating Ip and Private Ip, security group and when I see events in Heat stack where heat stack is in create progress and few things like etcd_lb, api_lb, network got completed in events. The only kube-master got stucked in create progress where it has stack resource group as OS::Heat::Resourcegroup and when I deep dive in Kube-master it shows one yaml called file:///usr/lib/python2.7/site-packages/magnum/drivers/k8s_fedora_atomic_v1/templates/kubemaster.yaml

When I'm checking kube-conductor logs it only shows kube-master create in progress and few lines which dont have any error.

I'm follwing below links to configure magnum in Openstack Queens https://docs.openstack.org/magnum/queens/install/install-rdo.html (https://docs.openstack.org/magnum/que...)

https://docs.openstack.org/magnum/queens/install/verify.html (https://docs.openstack.org/magnum/que...)

https://docs.openstack.org/magnum/queens/install/launch-instance.html (https://docs.openstack.org/magnum/que...)

When I'm verifying magnum operation it shows magnum-conductor up and running

Even the same cluster create_progress stuck result in Ocata ubuntu and Pike and queens centos

After a long time, the kubernetes cluster got failed, So, Pls help me anyone, Badly I wanted magnum. :)

Try the log files on the kubemaster instance (https://kubernetes.io/docs/tasks/debu...).

I hit this problem when trying to build a k8s cluster with TLS disabled. The root cause, I think, was that the /var/run/kubernetes directory on the cube master wasn't writeable by the kube user. When I modified it to 777, credentials appeared in the directory and the endpoint (:8080), sprang to life. I then hit the next set of problems...

BTW: I'm currently avoiding this issue by not disabling TLS in my k8s cluster. These bugs seem relevant:
