Node Group Operations
get node group details of the cluster
eksctl get nodegroup --cluster EKS-raman-cluster
scale-out node group to 5 nodes and then check no of instances created in EC2
eksctl scale nodegroup --cluster EKS-raman-cluster --name ng-1 --nodes 5 --nodes-max 5
scale in node group to 3 nodes and then check no of instances created in EC2
eksctl scale nodegroup --cluster EKS-raman-cluster --name ng-1 --nodes 3
create a new node group with spot instance and demand instance
First, create a yaml file as mentioned below (nodegroup.yml)
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
name: EKS-raman-cluster
region: us-east-1
nodeGroups:
- name: ng-1
instanceType: t2.small
desiredCapacity: 3
ssh: # use existing EC2 key
publicKeyName: vdevops
- name: ng-mixed
minSize: 3
maxSize: 5
instancesDistribution:
maxPrice: 0.2
instanceTypes: ["t2.small", "t3.small"]
onDemandBaseCapacity: 0
onDemandPercentageAboveBaseCapacity: 50
ssh:
publicKeyName: vdevops
Run the below command to create ng-mixed node group and after that check in the ec2 instances.
eksctl create nodegroup --config-file=nodegroup.yml --include='ng-mixed'
Run the below command to delete ng-mixed node group
eksctl delete nodegroup --config-file=nodegroup.yml --include=ng-mixed --approve
