| ### Example1 `values.yaml` | ||
|
|
||
| Below is an example for creation of a nodepool which can be modified inside values.yaml . | ||
|
|
||
| ```yaml | ||
| nodePools: | ||
| - name: default-nodepool | ||
| labels: | ||
| environment: production | ||
| annotations: | ||
| dedicated: true | ||
| requirements: | ||
| - key: "kubernetes.io/arch" | ||
| operator: "In" | ||
| values: | ||
| - amd64 | ||
| taints: | ||
| - key: "dedicated" | ||
| value: "true" | ||
| effect: "NoSchedule" | ||
| nodeClass: | ||
| group: karpenter.k8s.aws | ||
| kind: EC2NodeClass | ||
| name: default | ||
| expireAfter: 720h | ||
| limits: | ||
| cpu: "1000m" | ||
| memory: "2Gi" | ||
| disruption: | ||
| consolidationPolicy: "WhenEmptyOrUnderutilized" | ||
| consolidateAfter: "1m" | ||
| ``` | ||
| This `values.yaml` example deploys a Karpenter setup with a NodePool named `default-nodepool`, containing specifications such as labels, annotations, requirements, taints, node class, and limits. | ||
|
|
||
| ### Example2 `values.yaml` | ||

| # value: "special-value" | ||

| ``` | ||
|
|
||
|
|
||
| ### Notes: | ||
|
|
||
| - Refer to Example Folder for a example values.yaml file | ||
| - Karpenter automatically creates and manages NodePools as part of the installation process. | ||
| - Make sure to configure the IAM roles required by Karpenter for it to interact with EC2 instances and manage resources along with all prerequisites. | ||
| - The chart will ensure the Karpenter controller and NodePools are deployed correctly with all required configurations. | ||
