Only one node read on kubectl get nodes

0 votes

I'm trying to start a new Kubernetes cluster on AWS with the following settings:

export KUBERNETES_PROVIDER=aws

export KUBE_AWS_INSTANCE_PREFIX="k8-update-test"
export KUBE_AWS_ZONE="eu-west-1a"
export AWS_S3_REGION="eu-west-1"

export ENABLE_NODE_AUTOSCALER=true

export NON_MASQUERADE_CIDR="10.140.0.0/20"
export SERVICE_CLUSTER_IP_RANGE="10.140.1.0/24"
export DNS_SERVER_IP="10.140.1.10"

export MASTER_IP_RANGE="10.140.2.0/24"
export CLUSTER_IP_RANGE="10.140.3.0/24"

After running $KUBE_ROOT/cluster/kube-up.sh the master appears and 4 (default) minions are started. Unfortunately only one minion gets read. The result of kubectl get nodes is:

NAME                                         STATUS     AGE
ip-172-20-0-105.eu-west-1.compute.internal   NotReady   19h
ip-172-20-0-106.eu-west-1.compute.internal   NotReady   19h
ip-172-20-0-107.eu-west-1.compute.internal   Ready      19h
ip-172-20-0-108.eu-west-1.compute.internal   NotReady   19h

Why is that so?

I think your Cluster IP range is too small.
