| # karpenter | ||
|
|
||
| A Helm chart for Karpenter, an open-source node provisioning project built for Kubernetes. | ||
|
|
||
|    | ||
|
|
||
| ## Documentation | ||
|
|
||
| For full Karpenter documentation please checkout [https://karpenter.sh](https://karpenter.sh/docs/). | ||
|
|
||
| ## Installing the Chart | ||
|
|
||
| You can follow the detailed installation instruction in the [documentation](https://karpenter.sh/docs/getting-started/getting-started-with-karpenter) which covers the Karpenter prerequisites and installation options. The outcome of these instructions should result in something like the following command. | ||
|
|
||
| ```bash | ||
| helm upgrade --install --namespace karpenter --create-namespace \ | ||
| karpenter oci://public.ecr.aws/karpenter/karpenter \ | ||
| --version 1.0.0 \ | ||
| --set "serviceAccount.annotations.eks\.amazonaws\.com/role-arn=${KARPENTER_IAM_ROLE_ARN}" \ | ||
| --set settings.clusterName=${CLUSTER_NAME} \ | ||
| --set settings.interruptionQueue=${CLUSTER_NAME} \ | ||
| --wait | ||
| ``` | ||
|
|
||
| ### Verification | ||
|
|
||
| As the OCI Helm chart is signed by [Cosign](https://github.com/sigstore/cosign) as part of the release process you can verify the chart before installing it by running the following command. | ||
|
|
||
| ```shell | ||
| cosign verify public.ecr.aws/karpenter/karpenter:1.0.0 \ | ||
| --certificate-oidc-issuer=https://token.actions.githubusercontent.com \ | ||
| --certificate-identity-regexp='https://github\.com/aws/karpenter-provider-aws/\.github/workflows/release\.yaml@.+' \ | ||

| | imagePullPolicy | string | `"IfNotPresent"` | Image pull policy for Docker images. | | ||
| | imagePullSecrets | list | `[]` | Image pull secrets for Docker images. | | ||
| | logErrorOutputPaths | list | `["stderr"]` | Log errorOutputPaths - defaults to stderr only | | ||

| | settings.interruptionQueue | string | `""` | Interruption queue is the name of the SQS queue used for processing interruption events from EC2 Interruption handling is disabled if not specified. Enabling interruption handling may require additional permissions on the controller service account. Additional permissions are outlined in the docs. | | ||
| | settings.isolatedVPC | bool | `false` | If true then assume we can't reach AWS services which don't have a VPC endpoint This also has the effect of disabling look-ups to the AWS pricing endpoint | | ||
| | settings.reservedENIs | string | `"0"` | Reserved ENIs are not included in the calculations for max-pods or kube-reserved This is most often used in the VPC CNI custom networking setup https://docs.aws.amazon.com/eks/latest/userguide/cni-custom-network.html | | ||
