# with one t2.small and one t2.medium node.
make create

# delete the cluster
make delete

Download Client Binaries

The EKS User Guide mentions 2 binaries--kubectl and heptio-authenticator-aws--and this just downloads them into the current directory.

make -f eks.Makefile binaries

Single Node Type

# Create the EKS master nodes first
make -f eks.Makefile create

# Generate the kubeconfig file for kubectl
make -f eks.Makefile kubeconfig

# Create t2.medium worker nodes in an autoscaling group
# with a minimum of 1 node and a maximum of 2 nodes
make -f workers.Makefile create node_type=t2.medium min_node=1 max_node=2

# Using the Kubernetes cluster
export KUBECONFIG=$(pwd)/kubeconfig PATH=.:${PATH}
kubectl get nodes

# Shut down the worker nodes
make -f workers.Makefile create node_type=t2.medium

# Shut down the EKS master nodes
make -f eks.Makefile delete

Multiple Node Types

# Create the EKS master nodes first
make -f eks.Makefile create

# Generate the kubeconfig file for kubectl
make -f eks.Makefile kubeconfig

# Create t2.medium worker nodes in an autoscaling group
# with a minimum of 1 node and a maximum of 2 nodes
make -f workers.Makefile create node_type=t2.medium min_node=1 max_node=2

# Add 10 t2.small worker nodes
make -f workers.Makefile create node_type=t2.small min_node=10 max_node=10

# Using the Kubernetes cluster
export KUBECONFIG=$(pwd)/kubeconfig PATH=.:${PATH}
kubectl get nodes

# Shut down the worker nodes
make -f workers.Makefile create node_type=t2.medium
make -f workers.Makefile create node_type=t2.small

# Shut down the EKS master nodes
make -f eks.Makefile delete
