Update an Amazon EKS add-on

Amazon EKS doesnât automatically update an add-on when new versions are released or after you update your cluster to a new Kubernetes minor version. To update an add-on for an existing cluster, you must initiate the update. After you initiate the update, Amazon EKS updates the add-on for you. Before updating an add-on, review the current documentation for the add-on. For a list of available add-ons, see AWS add-ons. If the add-on requires an IAM role, see the details for the specific add-on in Available Amazon EKS add-ons from AWS for details about creating the role.

Prerequisites

Complete the following before you create an add-on:

Procedure

You can update an Amazon EKS add-on using eksctl, the AWS Management Console, or the AWS CLI.

Update add-on (eksctl)

Determine the current add-ons and add-on versions installed on your cluster. Replace my-cluster with the name of your cluster.
```
eksctl get addon --cluster my-cluster
```
An example output is as follows.
```
NAME        VERSION              STATUS  ISSUES  IAMROLE  UPDATE AVAILABLE
coredns     v1.8.7-eksbuild.2    ACTIVE  0
kube-proxy  v1.23.7-eksbuild.1   ACTIVE  0                v1.23.8-eksbuild.2
vpc-cni     v1.10.4-eksbuild.1   ACTIVE  0                v1.12.0-eksbuild.1,v1.11.4-eksbuild.1,v1.11.3-eksbuild.1,v1.11.2-eksbuild.1,v1.11.0-eksbuild.1
```
Your output might look different, depending on which add-ons and versions that you have on your cluster. You can see that in the previous example output, two existing add-ons on the cluster have newer versions available in the UPDATE AVAILABLE column.
Update the add-on.
1. Copy the command that follows to your device. Make the following modifications to the command as needed:
  - Replace my-cluster with the name of your cluster.
  - Replace region-code with the AWS Region that your cluster is in.
  - Replace vpc-cni with the name of an add-on returned in the output of the previous step that you want to update.
  - If you want to update to a version earlier than the latest available version, then replace latest with the version number returned in the output of the previous step that you want to use. Some add-ons have recommended versions. For more information, see the documentation for the add-on that youâre updating. For a list of add-ons, see AWS add-ons.* If the add-on uses a Kubernetes service account and IAM role, replace 111122223333 with your account ID and role-name with the name of an existing IAM role that youâve created. For instructions on creating the role, see the documentation for the add-on that youâre creating. For a list of add-ons, see AWS add-ons. Specifying a service account role requires that you have an IAM OpenID Connect (OIDC) provider for your cluster. To determine whether you have one for your cluster, or to create one, see Create an IAM OIDC provider for your cluster.
    
    If the add-on doesnât use a Kubernetes service account and IAM role, delete the serviceAccountRoleARN: arn:aws:iam::111122223333:role/role-name line.
  - The preserve option preserves existing values for the add-on. If you have set custom values for add-on settings, and you donât use this option, Amazon EKS overwrites your values with its default values. If you use this option, then we recommend that you test any field and value changes on a non-production cluster before updating the add-on on your production cluster. If you change this value to overwrite, all settings are changed to Amazon EKS default values. If youâve set custom values for any settings, they might be overwritten with Amazon EKS default values. If you change this value to none, Amazon EKS doesnât change the value of any settings, but the update might fail. If the update fails, you receive an error message to help you resolve the conflict.
```
cat >update-addon.yaml <<EOF
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
  name: my-cluster
  region: region-code

addons:
- name: vpc-cni
  version: latest
  serviceAccountRoleARN: arn:aws:iam::111122223333:role/role-name
  resolveConflicts: preserve
EOF
```
2. Run the modified command to create the update-addon.yaml file.
3. Apply the config file to your cluster.
```
eksctl update addon -f update-addon.yaml
```
For more information about updating add-ons, see Updating addons in the eksctl documentation.

Update add-on (AWS Console)

Open the Amazon EKS console.
In the left navigation pane, choose Clusters.
Choose the name of the cluster that you want to update the add-on for.
Choose the Add-ons tab.
Choose the add-on that you want to update.
Choose Edit.
On the Configure name of addon page, do the following:
1. Choose the Version that youâd like to use. The add-on might have a recommended version. For more information, see the documentation for the add-on that youâre updating. For a list of add-ons, see AWS add-ons.
2. You have two options for configuring roles for add-ons: EKS Pod Identities IAM role and IAM roles for service accounts (IRSA). Follow the appropriate step below for your preferred option. If all of the add-ons that you selected have Requires subscription under Status, choose Next. For the add-ons that donât have Requires subscription under Status, do the following:
  1. For Pod Identity IAM role for service account, you can either use an existing EKS Pod Identity IAM role or create one using the Create Recommended Role button. This field will only provide options with the appropriate trust policy. If thereâs no role to select, then you donât have an existing role with a matching trust policy. To configure an EKS Pod Identity IAM role for service accounts of the selected add-on, choose Create recommended role. The role creation wizard opens in a separate window. The wizard will automatically populate the role information as follows. For each add-on where you want to create the EKS Pod Identity IAM role, complete the steps in the IAM wizard as follows.
    - On the Select trusted entity step, the AWS service option for EKS and the use case for EKS - Pod Identity are preselected, and the appropriate trust policy will be automatically populated for the add-on. For example, the role will be created with the appropriate trust policy containing the pods.eks.amazonaws.com IAM Principal as detailed in Benefits of EKS Pod Identities. Choose Next.
    - On the Add permissions step, the appropriate managed policy for the role policy is preselected for the add-on. For example, for the Amazon VPC CNI add-on, the role will be created with the managed policy AmazonEKS_CNI_Policy as detailed in Amazon VPC CNI plugin for Kubernetes. Choose Next.
    - On the Name, review, and create step, in Role name, the default role name is automatically populated for the add-on. For example, for the Amazon VPC CNI add-on, the role will be created with the name AmazonEKSPodIdentityAmazonVPCCNIRole. In Description, the default description is automatically populated with the appropriate description for the add-on. For example, for the Amazon VPC CNI add-on, the role will be created with the description Allows pods running in Amazon EKS cluster to access AWS resources. In Trust policy, view the populated trust policy for the add-on. Choose Create role.
      
      Note
      
      Retaining the default role name enables EKS to pre-select the role for add-ons in new clusters or when adding add-ons to existing clusters. You can still override this name and the role will be available for the add-on across your clusters, but the role will need to be manually selected from the drop down.
  2. For add-ons that do not have Requires subscription under Status and where you want to configure roles using IRSA, see the documentation for the add-on that youâre creating to create an IAM policy and attach it to a role. For a list of add-ons, see AWS add-ons. Selecting an IAM role requires that you have an IAM OpenID Connect (OIDC) provider for your cluster. To determine whether you have one for your cluster, or to create one, see Create an IAM OIDC provider for your cluster.
3. Expand the Optional configuration settings.
4. In Configuration values, enter any add-on specific configuration information. For more information, see the documentation for the add-on that youâre updating. For a list of add-ons, see AWS add-onsâ¦â For Conflict resolution method, select one of the options. If you have set custom values for add-on settings, we recommend the Preserve option. If you donât choose this option, Amazon EKS overwrites your values with its default values. If you use this option, then we recommend that you test any field and value changes on a non-production cluster before updating the add-on on your production cluster. If you change this value to overwrite, all settings are changed to Amazon EKS default values. If youâve set custom values for any settings, they might be overwritten with Amazon EKS default values. If you change this value to none, Amazon EKS doesnât change the value of any settings, but the update might fail. If the update fails, you receive an error message to help you resolve the conflict.
Choose Save changes.

Update add-on (AWS CLI)

You need version 2.12.3 or later or version 1.27.160 or later of the AWS Command Line Interface (AWS CLI) installed and configured on your device or AWS CloudShell. To check your current version, use aws --version | cut -d / -f2 | cut -d ' ' -f1. Package managers such yum, apt-get, or Homebrew for macOS are often several versions behind the latest version of the AWS CLI. To install the latest version, see Installing and Quick configuration with aws configure in the AWS Command Line Interface User Guide. The AWS CLI version that is installed in AWS CloudShell might also be several versions behind the latest version. To update it, see Installing AWS CLI to your home directory in the AWS CloudShell User Guide.

See a list of installed add-ons. Replace my-cluster with the name of your cluster.

aws eks list-addons --cluster-name my-cluster

An example output is as follows.

{
    "addons": [
        "coredns",
        "kube-proxy",
        "vpc-cni"
    ]
}

View the current version of the add-on that you want to update. Replace my-cluster with your cluster name and vpc-cni with the name of the add-on that you want to update.
```
aws eks describe-addon --cluster-name my-cluster --addon-name vpc-cni --query "addon.addonVersion" --output text
```
An example output is as follows.
```
v1.10.4-eksbuild.1
```

Determine which versions of the add-on are available for your clusterâs version. Replace 1.33 with your clusterâs version and vpc-cni with the name of the add-on that you want to update.

aws eks describe-addon-versions --kubernetes-version 1.33 --addon-name vpc-cni \
    --query 'addons[].addonVersions[].{Version: addonVersion, Defaultversion: compatibilities[0].defaultVersion}' --output table

An example output is as follows.

------------------------------------------
|          DescribeAddonVersions         |
+-----------------+----------------------+
| Defaultversion  |       Version        |
+-----------------+----------------------+
|  False          |  v1.12.0-eksbuild.1  |
|  True           |  v1.11.4-eksbuild.1  |
|  False          |  v1.10.4-eksbuild.1  |
|  False          |  v1.9.3-eksbuild.1   |
+-----------------+----------------------+

The version with True in the Defaultversion column is the version that the add-on is created with, by default.

Update your add-on. Copy the command that follows to your device. Make the following modifications to the command, as needed, and then run the modified command. For more information about this command, see update-addon in the Amazon EKS Command Line Reference.
- Replace my-cluster with the name of your cluster.
- Replace vpc-cni with the name of the add-on that you want to update that was returned in the output of a previous step.
- Replace version-number with the version returned in the output of the previous step that you want to update to. Some add-ons have recommended versions. For more information, see the documentation for the add-on that youâre updating. For a list of add-ons, see AWS add-ons.* If the add-on uses a Kubernetes service account and IAM role, replace 111122223333 with your account ID and role-name with the name of an existing IAM role that youâve created. For instructions on creating the role, see the documentation for the add-on that youâre creating. For a list of add-ons, see AWS add-ons. Specifying a service account role requires that you have an IAM OpenID Connect (OIDC) provider for your cluster. To determine whether you have one for your cluster, or to create one, see Create an IAM OIDC provider for your cluster.
  
  If the add-on doesnât use a Kubernetes service account and IAM role, delete the serviceAccountRoleARN: arn:aws:iam::111122223333:role/role-name line.
- The --resolve-conflicts PRESERVE option preserves existing values for the add-on. If you have set custom values for add-on settings, and you donât use this option, Amazon EKS overwrites your values with its default values. If you use this option, then we recommend that you test any field and value changes on a non-production cluster before updating the add-on on your production cluster. If you change this value to OVERWRITE, all settings are changed to Amazon EKS default values. If youâve set custom values for any settings, they might be overwritten with Amazon EKS default values. If you change this value to NONE, Amazon EKS doesnât change the value of any settings, but the update might fail. If the update fails, you receive an error message to help you resolve the conflict.
- If you want to remove all custom configuration then perform the update using the --configuration-values '{}' option. This sets all custom configuration back to the default values. If you donât want to change your custom configuration, donât provide the --configuration-values flag. If you want to adjust a custom configuration then replace {} with the new parameters.
```
aws eks update-addon --cluster-name my-cluster --addon-name vpc-cni --addon-version version-number \
    --service-account-role-arn arn:aws:iam::111122223333:role/role-name --configuration-values '{}' --resolve-conflicts PRESERVE
```
Check the status of the update. Replace my-cluster with the name of your cluster and vpc-cni with the name of the add-on youâre updating.
```
aws eks describe-addon --cluster-name my-cluster --addon-name vpc-cni
```
An example output is as follows.
```
{
    "addon": {
        "addonName": "vpc-cni",
        "clusterName": "my-cluster",
        "status": "UPDATING",
    }
}
```
The update is complete when the status is ACTIVE.
