Creation Procedure

Create Resources

Create a dedicated VPC and associated resources using the pre-defined CloudFormation stack as described here: https://docs.aws.amazon.com/eks/latest/userguide/getting-started-console.html.

• Use "public and private subnets" option.
• Do not specify an IAM role.

Write down the name of the stack, as it may be needed to delete the resources.

Also write down VpcId, SecurityGroups, SubnetId

Create the Cluster Service Role

For an explanation of what a cluster service role is see:

Cluster Service Role

Creation:

https://docs.aws.amazon.com/eks/latest/userguide/service_IAM_role.html#create-service-role

IAM console → Create role → AWS Service → Select a service to view its use cases → EKS → Select your use case → EKS Cluster → Next: Permissions (by default AmazonEKSClusterPolicy is selected) → Next: Tags

Role name:

<cluster-name>-service-role

Create the Cluster

The cluster will be accessible to the IAM User that creates it without any additional configuration. Other users can be added as described in the Allowing Additional Users to Access the EKS Cluster section, after the cluster is created.

Create the cluster.

From the Console → EKS → Create Cluster

Name: ...

Cluster Service Role: the role created above, <cluster-name>-service-role.

Next.

VPC.

Subnets (all existing are preselected)

Security groups: use the security group created by the CloudFormation stack <cluster-name>-*-ControlPlaneSecurityGroup-*

Cluster Endpoint Access: Public and private.

Next.

Control Plane Logging: all disabled.

Create.

Test Access

At this point there are no nodes, but the cluster should be available. You can set up a "creator" context as described here, using the same IAM User identity (not a role): Connect to an EKS Cluster with kubectl.

Provision Compute Nodes

Create a Compute IAM Role

Create a "compute" Role.

AWS Services → EC2 → EC2 → add AmazonEKSWorkerNodePolicy, AmazonEKS_CNI_Policy, AmazonEC2ContainerRegistryReadOnly policies)

Name:

<cluster-name>-compute-role

Create Node Group

Select the EKS cluster, go to Compute

Add Node Group.

Name <cluster-name>-node-group

Node IAM role - the one created previously.

Next.

AMI type: Amazon Linux 2

Instance type: t3.2xlarge

Disk size: 20

Minimus size: 3 Maximu size: 3 Desired size: 3

Next

Select only the private subnets.

SSH Key Pair - this gives access to the nodes.

Allow remote access from: All

Create.

kubectl get nodes

Configure Access

Allowing Additional Users to Access the Cluster

Deletion Procedure

Delete Nodes and Cluster

Delete Nodes

Go to the cluster → Compute → Node Groups → Select → Delete.

Deleting the Node Group automatically terminates and deletes the instances.

Delete the Cluster

Delete the cluster.

Delete the Associated Resources

Remove the associated resources (subnets, VPC, etc.) by running Delete on the CloudFormation stack used to create resources.
