Provision a new Node Group

Create an EKS managed node group:

~$aws eks create-nodegroup --region $AWS_DEFAULT_REGION \

--cluster-name $EKS_CLUSTER_NAME \

--nodegroup-name custom-networking \

--instance-types t3.medium --node-role $MANAGED_NODE_GROUP_IAM_ROLE_ARN \

--subnets $PRIMARY_SUBNET_1 $PRIMARY_SUBNET_2 $PRIMARY_SUBNET_3 \

--labels type=customnetworking \

--scaling-config minSize=1,maxSize=1,desiredSize=1

Node group creation takes several minutes. You can wait for the node group creation to complete using this command:

~$aws eks wait nodegroup-active --cluster-name $EKS_CLUSTER_NAME --nodegroup-name custom-networking

Once this is complete we can see the new nodes registered in the EKS cluster:

~$kubectl get nodes -L eks.amazonaws.com/nodegroup

You can see that 1 new node provisioned labeled with the name of the new node group.
