Cluster Creation EKS

• When asked for roles, do not use LabRole, use the other one that usually has the word EKS in it.

• Navigate to EKS service

  • Create Cluster
  • I got it to work with and without quick configuration.
  • Give a unique name
  • Most recent K8s version
  • Select LabEksClusterRole for thee Cluster IAM role
  • Select LabRole for Node IAM role
  • Use default VPC
  • Select only subnets in US-east-1a and US-east-1b
  • Click ‘Create’
  • Takes a while to create.

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

Now create a service of type LoadBalancer

    apiVersion: v1
    kind: Service
    metadata:
      name: nginx
      labels:
        app: nginx
      annotations:
        service.beta.kubernetes.io/aws-load-balancer-scheme: "internet-facing"
    spec:
      type: LoadBalancer
      loadBalancerClass: eks.amazonaws.com/nlb
      selector:
        app: nginx
      ports:
        - name: http
          port: 80
          targetPort: 80
          protocol: TCP

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. (Make sure you use http and NOT https)
