Cluster Creation EKS

• Navigate to EKS service
  • Add cluster
  • Give a unique name
  • Most recent K8s version
  • Select LabRole
  • Next
  • Use default VPC
  • Select only subnets in US-east-1a and US-east-1b
  • Default sg
  • Next
  • Next
  • Create
  • Takes a while to create.
• After creation
  • Select the cluster -> compute -> Add node group
  • Unique name for group
  • LabRole for IAM role
  • I set the number of nodes to 4
  • next
  • Amazon Linux 2, t2.medium (micro is to small. Use medium)
  • next
  • Make sure you are using same subnets from above
  • Next
  • Create
• Takes a few minutes for nodes to come online.

Connect kubectl to AWS

I started with a blank ubuntu vm (one that had no other garbage on it):

• Create an $HOME/.aws/credentials file with contents given on lab console.
• Install awscli from source: here
• aws sts get-caller-identity (verifies connectivity)
• aws eks --region us-east-1 update-kubeconfig --name testcluster, this will put connection settings in a file to interact with EKS. (Assuming your cluster that you created above is named testcluster, if not, change this command to reflect your cluster name)
• install kubectl, follow instructions here
• kubectl get nodes, may not have any nodes until they come online from part one.
• kubectl create deployment --image=nginx nginx --dry-run=client -o yaml > nginx.yaml
• apply the file
• kubectl create service loadbalancer nginx --tcp=80:80 --dry-run=client -o yaml > lb.yml
• apply the file

You should be able to see a public endpoint for kubectl get svc. See if you can connect and see nginx. Might take a few minutes.
