Integrate with EKS

Create an integration to manage access to a Kubernetes cluster on AWS

​​

With Elastic Kubernetes Service (EKS) on AWS, EKS simplifies the management complexities of Kubernetes.

Through this integration, Apono helps you securely manage access to your AWS Elastic Kubernetes cluster.​

---

Prerequisites

Item	Description
Apono Connector	​Connection installed on the EKS cluster that serves as a bridge between the cluster and Apono
Apono Premium	​Apono plan providing all available features and dedicated account support
Cluster Admin Access	Admin access to the cluster to integrate The cluster admin access can be the built-in cluster-admin role or equivalent permission level. Apono does not require admin permissions to the Kubernetes environment.
EKS Cluster Name	Unique name of the cluster to integrate
AWS SSO | SAML Federation	Authentication for requester Security Assertion Markup Language (SAML) federation for authentication can be provided by providers such as Okta, Onelogin, Jumpcloud, and Ping Identity.

​

---

Configure user authentication

Authentication can be completed with an Identity and Access Management IAM user or an IAM role. To grant a user access to an EKS cluster, the IAM user or IAM role must be mapped with a specific user identifier, such as an email address.Apono supports this mapping with an IAM role through AWS SSO or SAML federation from any identity provider (IdP).​

Create a new policy

Follow these steps to create a new policy:

1. Under Access management on the Identity and Access Management (IAM) page in AWS, click Policies > Create policy. The Specify permission page appears.

2. Click JSON.

1. Click Next. The Add permissions page appears.

2. Under Permissions policies, select the newly created policy.

3. Click Next. The Name, review, and create page appears.

4. For the Role name, enter apono-k8s-access.

5. For the Description, enter required for k8s access managed by Apono.

6. Click Create role.

If an Overly permission trust policy popup window appears, click Continue.

Authenticate the EKS cluster

Now that the IAM role has been created, you must authenticate the EKS cluster with the ConfigMap or EKS API.

ConfigMap

Read Apply the aws-auth ConfigMap to your cluster to learn more about editing the aws-auth ConfigMap.

Follow these steps to authenticate the cluster:

1. Log into the EKS cluster with a user account that has the cluster admin permission.

2. Edit the aws-auth ConfigMap to include the following mapRoles entry. Be sure to replace the placeholder.

   - rolearn: arn:aws:iam::<AWS_ACCOUNT_ID>:role/apono-k8s-access
     username: "{{SessionNameRaw}}"

   Placeholder	Description
   <AWS_ACCOUNT_ID>	AWS account ID where the EKS is hosted

EKS API

Follow these steps to authenticate the cluster:

1. Change the authentication mode to EKS API.

2. Create the access entry:

   • For the IAM principal, enter arn:aws:iam::<AWS_ACCOUNT_ID>:role/apono-k8s-access.

   • For the Username use apono:{{SessionName}}.

   • Choose Cluster as the access scope.

Now, you can integrate with EKS.
