# UpdateAddon Updates an Amazon EKS add-on. ## Request Syntax ``` POST /clusters/name/addons/addonName/update HTTP/1.1 Content-type: application/json { "addonVersion": "string", "clientRequestToken": "string", "configurationValues": "string", "podIdentityAssociations": [ { "roleArn": "string", "serviceAccount": "string" } ], "resolveConflicts": "string", "serviceAccountRoleArn": "string" } ``` ## URI Request Parameters The request uses the following URI parameters. ** [addonName](#API_UpdateAddon_RequestSyntax) ** The name of the add-on. The name must match one of the names returned by [https://docs.aws.amazon.com/eks/latest/APIReference/API_ListAddons.html](https://docs.aws.amazon.com/eks/latest/APIReference/API_ListAddons.html). Required: Yes ** [name](#API_UpdateAddon_RequestSyntax) ** The name of your cluster. Length Constraints: Minimum length of 1. Maximum length of 100. Pattern: `^[0-9A-Za-z][A-Za-z0-9\-_]*` Required: Yes ## Request Body The request accepts the following data in JSON format. ** [addonVersion](#API_UpdateAddon_RequestSyntax) ** The version of the add-on. The version must match one of the versions returned by [https://docs.aws.amazon.com/eks/latest/APIReference/API_DescribeAddonVersions.html](https://docs.aws.amazon.com/eks/latest/APIReference/API_DescribeAddonVersions.html). Type: String Required: No ** [clientRequestToken](#API_UpdateAddon_RequestSyntax) ** A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Type: String Required: No ** [configurationValues](#API_UpdateAddon_RequestSyntax) ** The set of configuration values for the add-on that's created. The values that you provide are validated against the schema returned by `DescribeAddonConfiguration`. Type: String Required: No ** [podIdentityAssociations](#API_UpdateAddon_RequestSyntax) ** An array of EKS Pod Identity associations to be updated. Each association maps a Kubernetes service account to an IAM role. If this value is left blank, no change. If an empty array is provided, existing associations owned by the add-on are deleted. For more information, see [Attach an IAM Role to an Amazon EKS add-on using EKS Pod Identity](https://docs.aws.amazon.com/eks/latest/userguide/add-ons-iam.html) in the *Amazon EKS User Guide*. Type: Array of [AddonPodIdentityAssociations](API_AddonPodIdentityAssociations.md) objects Required: No ** [resolveConflicts](#API_UpdateAddon_RequestSyntax) ** How to resolve field value conflicts for an Amazon EKS add-on if you've changed a value from the Amazon EKS default value. Conflicts are handled based on the option you choose: + **None** – Amazon EKS doesn't change the value. The update might fail. + **Overwrite** – Amazon EKS overwrites the changed value back to the Amazon EKS default value. + **Preserve** – Amazon EKS preserves the value. If you choose this option, we recommend that you test any field and value changes on a non-production cluster before updating the add-on on your production cluster. Type: String Valid Values: `OVERWRITE | NONE | PRESERVE` Required: No ** [serviceAccountRoleArn](#API_UpdateAddon_RequestSyntax) ** The Amazon Resource Name (ARN) of an existing IAM role to bind to the add-on's service account. The role must be assigned the IAM permissions required by the add-on. If you don't specify an existing IAM role, then the add-on uses the permissions assigned to the node IAM role. For more information, see [Amazon EKS node IAM role](https://docs.aws.amazon.com/eks/latest/userguide/create-node-role.html) in the *Amazon EKS User Guide*. To specify an existing IAM role, you must have an IAM OpenID Connect (OIDC) provider created for your cluster. For more information, see [Enabling IAM roles for service accounts on your cluster](https://docs.aws.amazon.com/eks/latest/userguide/enable-iam-roles-for-service-accounts.html) in the *Amazon EKS User Guide*. Type: String Length Constraints: Minimum length of 1. Maximum length of 255.

HTTP Status Code: 500 ## Examples In the following example or examples, the Authorization header contents (`AUTHPARAMS`) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see [Signature Version 4 Signing Process](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html) in the *Amazon EKS General Reference*. You need to learn how to sign HTTP requests only if you intend to manually create them. When you use the [AWS Command Line Interface (AWS CLI)](http://aws.amazon.com/cli/) or one of the [AWS SDKs](http://aws.amazon.com/tools/) to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself. ### Example The following example updates an add-on named `vpc-cni` to use an IAM role named `AmazonEKSCNIRole` and to overwrite the add-on's existing configuration with the Amazon EKS add-on's configuration. #### Sample Request ``` POST /clusters/my-cluster/addons/vpc-cni/update HTTP/1.1 Host: eks.us-west-2.amazonaws.com Accept-Encoding: identity User-Agent: aws-cli/1.16.298 Python/3.6.0 Windows/10 botocore/1.13.34 X-Amz-Date: 20201125T145528Z Authorization: AUTHPARAMS { "serviceAccountRoleArn": "arn:aws:iam::012345678910:role/AmazonEKSCNIRole", "resolveConflicts": "overwrite", "clientRequestToken": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" } ``` #### Sample Response ``` HTTP/1.1 200 OK Date: Wed, 25 Nov 2020 14:55:29 GMT Content-Type: application/json Content-Length: 288 x-amzn-RequestId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx x-amz-apigw-id: WkZ_KGiBvHcFhtw= X-Amzn-Trace-Id: Root=1-xxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxx Connection: keep-alive { "update": { "id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", "status": "InProgress", "type": "AddonUpdate", "params": [{ "type": "ServiceAccountRoleArn", "value": "arn:aws:iam::012345678910:role/AmazonEKSCNIRole" }, { "type": "ResolveConflicts", "value": "overwrite" }], "createdAt": 1606316129.051, "errors": [] } } ``` ## See Also For more information about using this API in one of the language-specific AWS SDKs, see the following: + [AWS Command Line Interface V2](https://docs.aws.amazon.com/goto/cli2/eks-2017-11-01/UpdateAddon) + [AWS SDK for .NET V4](https://docs.aws.amazon.com/goto/DotNetSDKV4/eks-2017-11-01/UpdateAddon) + [AWS SDK for C\$1\$1](https://docs.aws.amazon.com/goto/SdkForCpp/eks-2017-11-01/UpdateAddon) + [AWS SDK for Go v2](https://docs.aws.amazon.com/goto/SdkForGoV2/eks-2017-11-01/UpdateAddon) + [AWS SDK for Java V2](https://docs.aws.amazon.com/goto/SdkForJavaV2/eks-2017-11-01/UpdateAddon) + [AWS SDK for JavaScript V3](https://docs.aws.amazon.com/goto/SdkForJavaScriptV3/eks-2017-11-01/UpdateAddon) + [AWS SDK for Kotlin](https://docs.aws.amazon.com/goto/SdkForKotlin/eks-2017-11-01/UpdateAddon) + [AWS SDK for PHP V3](https://docs.aws.amazon.com/goto/SdkForPHPV3/eks-2017-11-01/UpdateAddon) + [AWS SDK for Python](https://docs.aws.amazon.com/goto/boto3/eks-2017-11-01/UpdateAddon) + [AWS SDK for Ruby V3](https://docs.aws.amazon.com/goto/SdkForRubyV3/eks-2017-11-01/UpdateAddon)
