Create a Kubernetes Cluster on AWS¶
In this tutorial, we will create a Kubernetes Cluster on AWS different A-Zone, and will reference this https://kubernetes.io/docs/admin/multiple-zones/
Please make sure you have installed awscli (https://aws.amazon.com/cli/)
Create the cluster¶
curl -sS https://get.k8s.io | MULTIZONE=true KUBERNETES_PROVIDER=aws KUBE_AWS_ZONE=us-west-2a NUM_NODES=1 bash
This command will create a k8s cluster which include one master node and one worker node.
Add more nodes to the cluster¶
KUBE_USE_EXISTING_MASTER=true MULTIZONE=true KUBERNETES_PROVIDER=aws KUBE_AWS_ZONE=us-west-2b NUM_NODES=2 KUBE_SUBNET_CIDR=172.20.1.0/24 MASTER_INTERNAL_IP=172.20.0.9 kubernetes/cluster/kube-up.sh
This will create two worker nodes in another zone us-west-2b.
Check our cluster¶
➜ ~ kubectl get nodes --show-labels
