This component provisions Karpenter on an EKS cluster. It requires at least version 0.32.0 of Karpenter, though you are encouraged to use the latest version.

Usage

Stack Level: Regional

These instructions assume you are provisioning 2 EKS clusters in the same account and region, named "blue" and "green", and alternating between them. If you are only using a single cluster, you can ignore the "blue" and "green" references and remove the metadata block from the karpenter module.

Provision Karpenter on EKS cluster

Here we describe how to provision Karpenter on an EKS cluster. We will be using the plat-ue2-dev stack as an example.

Provision Service-Linked Roles for EC2 Spot and EC2 Spot Fleet

Note: If you want to use EC2 Spot for the instances launched by Karpenter, you may need to provision the following Service-Linked Role for EC2 Spot:

This is only necessary if this is the first time you're using EC2 Spot in the account. Since this is a one-time operation, we recommend you do this manually via the AWS CLI:

aws --profile <namespace>-<tenamt>-gbl-<stage>-admin iam create-service-linked-role --aws-service-name spot.amazonaws.com

Note that if the Service-Linked Roles already exist in the AWS account (if you used EC2 Spot or Spot Fleet before), and you try to provision them again, you will see the following errors:

An error occurred (InvalidInput) when calling the CreateServiceLinkedRole operation:
Service role name AWSServiceRoleForEC2Spot has been taken in this account, please try a different suffix

For more details, see:

The process of provisioning Karpenter on an EKS cluster consists of 3 steps.

1. Provision EKS IAM Role for Nodes Launched by Karpenter

[!NOTE]

VPC assumptions being made

We assume you've already created a VPC using our VPC component and have private subnets already set up. The Karpenter node pools will be launched in the private subnets.

EKS IAM Role for Nodes launched by Karpenter are provisioned by the eks/cluster component. (EKS can also provision a Fargate Profile for Karpenter, but deploying Karpenter to Fargate is not recommended.):

components:
  terraform:
    eks/cluster-blue:
      metadata:
        component: eks/cluster
        inherits:
          - eks/cluster
      vars:
        karpenter_iam_role_enabled: true

[!NOTE]

The AWS Auth API for EKS is used to authorize the Karpenter controller to interact with the EKS cluster.

Karpenter is installed using a Helm chart. The Helm chart installs the Karpenter controller and a webhook pod as a Deployment that needs to run before the controller can be used for scaling your cluster. We recommend a minimum of one small node group with at least one worker node.

As an alternative, you can run these pods on EKS Fargate by creating a Fargate profile for the karpenter namespace. Doing so will cause all pods deployed into this namespace to run on EKS Fargate. Do not run Karpenter on a node that is managed by Karpenter.

See Run Karpenter Controller... for more details.

We provision IAM Role for Nodes launched by Karpenter because they must run with an Instance Profile that grants permissions necessary to run containers and configure networking.

We define the IAM role for the Instance Profile in components/terraform/eks/cluster/controller-policy.tf.

Note that we provision the EC2 Instance Profile for the Karpenter IAM role in the components/terraform/eks/karpenter component (see the next step).

Run the following commands to provision the EKS Instance Profile for Karpenter and the IAM role for instances launched by Karpenter on the blue EKS cluster and add the role ARNs to the EKS Auth API:

atmos terraform plan eks/cluster-blue -s plat-ue2-dev
atmos terraform apply eks/cluster-blue -s plat-ue2-dev

For more details, refer to:

2. Provision karpenter component

In this step, we provision the components/terraform/eks/karpenter component, which deploys the following resources:

Create a stack config for the blue Karpenter component in stacks/catalog/eks/clusters/blue.yaml:

eks/karpenter-blue:
  metadata:
    component: eks/karpenter
    inherits:
      - eks/karpenter
  vars:
    eks_component_name: eks/cluster-blue

Run the following commands to provision the Karpenter component on the blue EKS cluster:

atmos terraform plan eks/karpenter-blue -s plat-ue2-dev
atmos terraform apply eks/karpenter-blue -s plat-ue2-dev

3. Provision karpenter-node-pool component

In this step, we provision the components/terraform/eks/karpenter-node-pool component, which deploys Karpenter NodePools using the kubernetes_manifest resource.

[!TIP]

Why use a separate component for NodePools?

We create the NodePools as a separate component since the CRDs for the NodePools are created by the Karpenter component. This helps manage dependencies.

First, create an abstract component for the eks/karpenter-node-pool component:

components:
  terraform:
    eks/karpenter-node-pool:
      metadata:
        type: abstract
      vars:
        enabled: true
        # Disabling Manifest Experiment disables stored metadata with Terraform state
        # Otherwise, the state will show changes on all plans
        helm_manifest_experiment_enabled: false
        node_pools:
          default:
            # Whether to place EC2 instances launched by Karpenter into VPC private subnets. Set it to `false` to use public subnets
            private_subnets_enabled: true
            # You can use disruption to set the maximum instance lifetime for the EC2 instances launched by Karpenter.
            # You can also configure how fast or slow Karpenter should add/remove nodes.
            # See more: https://karpenter.sh/v0.36/concepts/disruption/
            disruption:
              max_instance_lifetime: "336h" # 14 days
            # Taints can be used to prevent pods without the right tolerations from running on this node pool.
            # See more: https://karpenter.sh/v0.36/concepts/nodepools/#taints
            taints: []
            total_cpu_limit: "1k"
            # Karpenter node pool total memory limit for all pods running on the EC2 instances launched by Karpenter
            total_memory_limit: "1200Gi"
            # Set acceptable (In) and unacceptable (Out) Kubernetes and Karpenter values for node provisioning based on
            # Well-Known Labels and cloud-specific settings. These can include instance types, zones, computer architecture,
            # and capacity type (such as AWS spot or on-demand).
            # See https://karpenter.sh/v0.36/concepts/nodepools/#spectemplatespecrequirements for more details
            requirements:
              - key: "karpenter.sh/capacity-type"
                operator: "In"
                # See https://karpenter.sh/docs/concepts/nodepools/#capacity-type
                # Allow fallback to on-demand instances when spot instances are unavailable
                # By default, Karpenter uses the "price-capacity-optimized" allocation strategy
                # https://aws.amazon.com/blogs/compute/introducing-price-capacity-optimized-allocation-strategy-for-ec2-spot-instances/
                # It is currently not configurable, but that may change in the future.
                # See https://github.com/aws/karpenter-provider-aws/issues/1240
                values:
                  - "on-demand"
                  - "spot"
              - key: "kubernetes.io/os"
                operator: "In"
                values:
                  - "linux"
              - key: "kubernetes.io/arch"
                operator: "In"
                values:
                  - "amd64"
              # The following two requirements pick instances such as c3 or m5
              - key: karpenter.k8s.aws/instance-category
                operator: In
                values: ["c", "m", "r"]
              - key: karpenter.k8s.aws/instance-generation
                operator: Gt
                values: ["2"]

Now, create the stack config for the blue Karpenter NodePool component in stacks/catalog/eks/clusters/blue.yaml:

eks/karpenter-node-pool/blue:
  metadata:
    component: eks/karpenter-node-pool
    inherits:
      - eks/karpenter-node-pool
  vars:
    eks_component_name: eks/cluster-blue

Finally, run the following commands to deploy the Karpenter NodePools on the blue EKS cluster:

atmos terraform plan eks/karpenter-node-pool/blue -s plat-ue2-dev
atmos terraform apply eks/karpenter-node-pool/blue -s plat-ue2-dev

Node Interruption

Karpenter also supports listening for and responding to Node Interruption events. If interruption handling is enabled, Karpenter will watch for upcoming involuntary interruption events that would cause disruption to your workloads. These interruption events include:

[!TIP]

Interruption Handler vs. Termination Handler

The Node Interruption Handler is not the same as the Node Termination Handler. The latter is always enabled and cleanly shuts down the node in 2 minutes in response to a Node Termination event. The former gets advance notice that a node will soon be terminated, so it can have 5-10 minutes to shut down a node.

For more details, see refer to the Karpenter docs and FAQ

To enable Node Interruption handling, set var.interruption_handler_enabled to true. This will create an SQS queue and a set of Event Bridge rules to deliver interruption events to Karpenter.

Custom Resource Definition (CRD) Management

Karpenter ships with a few Custom Resource Definitions (CRDs). In earlier versions of this component, when installing a new version of the karpenter helm chart, CRDs were not be upgraded at the same time, requiring manual steps to upgrade CRDs after deploying the latest chart. However Karpenter now supports an additional, independent helm chart for CRD management. This helm chart, karpenter-crd, can be installed alongside the karpenter helm chart to automatically manage the lifecycle of these CRDs.

To deploy the karpenter-crd helm chart, set var.crd_chart_enabled to true. (Installing the karpenter-crd chart is recommended. var.crd_chart_enabled defaults to false to preserve backward compatibility with older versions of this component.)
