Kubernetes API Server: Unable to listen for secure
I am trying to setup Kubernetes for the first time. I am following the Fedora Manual installation guide: http://kubernetes.io/v1.0/docs/getting-started-guides/fedora/fedora_manual_config.html
I checked the logs of my API server and am getting this error:
server.go:464] Unable to listen for secure (open /var/run/kubernetes/apiserver.crt: no such file or directory); will try again.
I assume it needs some sort of cert but the installation guide doesnt mention anything about this. Here is what my apiserver config file looks like
# The address on the local server to listen to.
KUBE_API_ADDRESS="--address=0.0.0.0"
# The port on the local server to listen on.
KUBE_API_PORT="--port=8080"
# Port node listen on
KUBELET_PORT="--kubelet_port=10250"
# Location of the etcd cluster
#KUBE_ETCD_SERVERS="--etcd_servers=http://vagrant-master:4001"
KUBE_ETCD_SERVERS="--etcd_servers=http://127.0.0.1:4001"
# Address range to use for services
KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16"
# default admission control policies
KUBE_ADMISSION_CONTROL="--admission_control=NamespaceAutoProvision,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota"
# Add your own!
KUBE_API_ARGS="--service_account_key_file=/etc/kubernetes/certs/serviceaccount.key"
Here is my service status
kube-apiserver.service - Kubernetes API Server

How can i fix this error?
By default, the kube-apiserver process tries to open a secure (https) server port on port 6443 using credentials from the directory /var/run/kubernetes . If you want to disable the secure port, you can pass --secure-port=0 which should make your error go away. Alternatively, you can manually create certificates for your cluster so that the process is able to successfully open the secure port.
this is a bug in kube-apiserver. https://bugzilla.redhat.com/show_bug.cgi?id=1201965
