Managing the Amazon EBS CSI driver as an Amazon EKS add-on

To improve security and reduce the amount of work, you can manage the Amazon EBS CSI driver as an Amazon EKS add-on. For information about Amazon EKS add-ons, see Amazon EKS add-ons. You can add the Amazon EBS CSI add-on by following the steps in Adding the Amazon EBS CSI driver add-on.

If you added the Amazon EBS CSI add-on, you can manage it by following the steps in the Updating the Amazon EBS CSI driver as an Amazon EKS add-on and Removing the Amazon EBS CSI add-on sections.

Prerequisites

  • An existing cluster. To see the required platform version, run the following command.

    aws eks describe-addon-versions --addon-name aws-ebs-csi-driver

  • An existing Amazon Identity and Access Management (IAM) OpenID Connect (OIDC) provider for your cluster. To determine whether you already have one, or to create one, see Creating an IAM OIDC provider for your cluster.

  • An Amazon EBS CSI driver IAM role. If you don't satisfy this prerequisite, attempting to install the add-on and running kubectl describe pvc will show failed to provision volume with StorageClass along with a could not create volume in EC2: UnauthorizedOperation error. For more information, see Creating the Amazon EBS CSI driver IAM role.

  • If you're using a cluster wide restricted PodSecurityPolicy, make sure that the add-on is granted sufficient permissions to be deployed. For the permissions required by each add-on Pod, see the relevant add-on manifest definition on GitHub.

Important

To use the snapshot functionality of the Amazon EBS CSI driver, you must install the external snapshotter before the installation of the add-on. The external snapshotter components must be installed in the following order:

For more information, see CSI Snapshotter on GitHub.

Adding the Amazon EBS CSI driver add-on

Important

Before adding the Amazon EBS driver as an Amazon EKS add-on, confirm that you don't have a self-managed version of the driver installed on your cluster. If so, see Uninstalling a self-managed Amazon EBS CSI driver on GitHub.

You can use eksctl, the Amazon Web Services Management Console, or the Amazon CLI to add the Amazon EBS CSI add-on to your cluster.

eksctl
To add the Amazon EBS CSI add-on using eksctl

Run the following command. Replace my-cluster with the name of your cluster, 111122223333 with your account ID, and AmazonEKS_EBS_CSI_DriverRole with the name of the IAM role created earlier. 

eksctl create addon --name aws-ebs-csi-driver --cluster my-cluster --service-account-role-arn arn:aws-cn:iam::111122223333:role/AmazonEKS_EBS_CSI_DriverRole --force

If you remove the --force option and any of the Amazon EKS add-on settings conflict with your existing settings, then updating the Amazon EKS add-on fails, and you receive an error message to help you resolve the conflict. Before specifying this option, make sure that the Amazon EKS add-on doesn't manage settings that you need to manage, because those settings are overwritten with this option. For more information about other options for this setting, see Addons in the eksctl documentation. For more information about Amazon EKS Kubernetes field management, see Kubernetes field management.

Amazon Web Services Management Console
To add the Amazon EBS CSI add-on using the Amazon Web Services Management Console

  1. Open the Amazon EKS console at https://console.amazonaws.cn/eks/home#/clusters.

  2. In the left navigation pane, choose Clusters.

  3. Choose the name of the cluster that you want to configure the Amazon EBS CSI add-on for.

  4. Choose the Add-ons tab.

  5. Choose Get more add-ons.

  6. On the Select add-ons page, do the following:

    1. In the Amazon EKS-addons section, select the Amazon EBS CSI Driver check box.

    2. Choose Next.

  7. On the Configure selected add-ons settings page, do the following:

    1. Select the Version you'd like to use.

    2. For Select IAM role, select the name of an IAM role that you attached the Amazon EBS CSI driver IAM policy to.

    3. (Optional) You can expand the Optional configuration settings. If you select Override for the Conflict resolution method, one or more of the settings for the existing add-on can be overwritten with the Amazon EKS add-on settings. If you don't enable this option and there's a conflict with your existing settings, the operation fails. You can use the resulting error message to troubleshoot the conflict. Before selecting this option, make sure that the Amazon EKS add-on doesn't manage settings that you need to self-manage.

    4. Choose Next.

  8. On the Review and add page, choose Create. After the add-on installation is complete, you see your installed add-on.

Amazon CLI
To add the Amazon EBS CSI add-on using the Amazon CLI

Run the following command. Replace my-cluster with the name of your cluster, 111122223333 with your account ID, and AmazonEKS_EBS_CSI_DriverRole with the name of the role that was created earlier. 

aws eks create-addon --cluster-name my-cluster --addon-name aws-ebs-csi-driver \
  --service-account-role-arn arn:aws-cn:iam::111122223333:role/AmazonEKS_EBS_CSI_DriverRole

Now that you have added the Amazon EBS CSI driver as an Amazon EKS add-on, you can continue to Deploy a sample application and verify that the CSI driver is working. That procedure includes setting up the storage class.

Updating the Amazon EBS CSI driver as an Amazon EKS add-on

Amazon EKS doesn't automatically update Amazon EBS CSI for your cluster when new versions are released or after you update your cluster to a new Kubernetes minor version. To update Amazon EBS CSI on an existing cluster, you must initiate the update and then Amazon EKS updates the add-on for you.

eksctl
To update the Amazon EBS CSI add-on using eksctl

  1. Check the current version of your Amazon EBS CSI add-on. Replace my-cluster with your cluster name.

    eksctl get addon --name aws-ebs-csi-driver --cluster my-cluster

    An example output is as follows.

    NAME                    VERSION                      STATUS  ISSUES  IAMROLE UPDATE AVAILABLE
aws-ebs-csi-driver      v1.11.2-eksbuild.1      ACTIVE  0               v1.11.4-eksbuild.1

  2. Update the add-on to the version returned under UPDATE AVAILABLE in the output of the previous step.

    eksctl update addon --name aws-ebs-csi-driver --version v1.11.4-eksbuild.1 --cluster my-cluster --force

    If you remove the --force option and any of the Amazon EKS add-on settings conflict with your existing settings, then updating the Amazon EKS add-on fails, and you receive an error message to help you resolve the conflict. Before specifying this option, make sure that the Amazon EKS add-on doesn't manage settings that you need to manage, because those settings are overwritten with this option. For more information about other options for this setting, see Addons in the eksctl documentation. For more information about Amazon EKS Kubernetes field management, see Kubernetes field management.

Amazon Web Services Management Console
To update the Amazon EBS CSI add-on using the Amazon Web Services Management Console

  1. Open the Amazon EKS console at https://console.amazonaws.cn/eks/home#/clusters.

  2. In the left navigation pane, choose Clusters.

  3. Choose the name of the cluster that you want to update the Amazon EBS CSI add-on for.

  4. Choose the Add-ons tab.

  5. Choose Amazon EBS CSI Driver.

  6. Choose Edit.

  7. On the Configure Amazon EBS CSI Driver page, do the following:

    1. Select the Version you'd like to use.

    2. For Select IAM role, select the name of an IAM role that you attached the Amazon EBS CSI driver IAM policy to.

    3. (Optional) You can expand the Optional configuration settings and modify as needed.

    4. Choose Save changes.

Amazon CLI
To update the Amazon EBS CSI add-on using the Amazon CLI

  1. Check the current version of your Amazon EBS CSI add-on. Replace my-cluster with your cluster name.

    aws eks describe-addon --cluster-name my-cluster --addon-name aws-ebs-csi-driver --query "addon.addonVersion" --output text

    An example output is as follows.

    v1.11.2-eksbuild.1

  2. Determine which versions of the Amazon EBS CSI add-on are available for your cluster version.

    aws eks describe-addon-versions --addon-name aws-ebs-csi-driver --kubernetes-version 1.23 \
  --query "addons[].addonVersions[].[addonVersion, compatibilities[].defaultVersion]" --output text

    An example output is as follows.

    v1.11.4-eksbuild.1
True
v1.11.2-eksbuild.1
False

    The version with True underneath is the default version deployed when the add-on is created. The version deployed when the add-on is created might not be the latest available version. In the previous output, the latest version is deployed when the add-on is created.

  3. Update the add-on to the version with True that was returned in the output of the previous step. If it was returned in the output, you can also update to a later version.

    aws eks update-addon --cluster-name my-cluster --addon-name aws-ebs-csi-driver --addon-version v1.11.4-eksbuild.1 \
  --resolve-conflicts PRESERVE

    The PRESERVE option preserves any custom settings that you've set for the add-on. For more information about other options for this setting, see update-addon in the Amazon EKS Command Line Reference. For more information about Amazon EKS add-on configuration management, see Kubernetes field management.

Removing the Amazon EBS CSI add-on

You have two options for removing an Amazon EKS add-on.

  • Preserve add-on software on your cluster – This option removes Amazon EKS management of any settings. It also removes the ability for Amazon EKS to notify you of updates and automatically update the Amazon EKS add-on after you initiate an update. However, it preserves the add-on software on your cluster. This option makes the add-on a self-managed installation, rather than an Amazon EKS add-on. With this option, there's no downtime for the add-on. The commands in this procedure use this option.

  • Remove add-on software entirely from your cluster – We recommend that you remove the Amazon EKS add-on from your cluster only if there are no resources on your cluster that are dependent on it. To do this option, delete --preserve from the command you use in this procedure.

If the add-on has an IAM account associated with it, the IAM account isn't removed.

You can use eksctl, the Amazon Web Services Management Console, or the Amazon CLI to remove the Amazon EBS CSI add-on.

eksctl
To remove the Amazon EBS CSI add-on using eksctl

Replace my-cluster with the name of your cluster, and then run the following command.
