View Kubernetes resources in the AWS Management Console

You can view the Kubernetes resources deployed to your cluster with the AWS Management Console. You can’t view Kubernetes resources with the AWS CLI or eksctl. To view Kubernetes resources using a command-line tool, use kubectl.

Note

To view the Resources tab and Nodes section on the Compute tab in the AWS Management Console, the IAM principal that you’re using must have specific IAM and Kubernetes permissions. For more information, see Required permissions.

  1. Open the Amazon EKS console.

  2. In the Clusters list, select the cluster that contains the Kubernetes resources that you want to view.

  3. Select the Resources tab.

  4. Select a Resource type group that you want to view resources for, such as Workloads. You see a list of resource types in that group.

  5. Select a resource type, such as Deployments, in the Workloads group. You see a description of the resource type, a link to the Kubernetes documentation for more information about the resource type, and a list of resources of that type that are deployed on your cluster. If the list is empty, then there are no resources of that type deployed to your cluster.

  6. Select a resource to view more information about it. Try the following examples:

    • Select the Workloads group, select the Deployments resource type, and then select the coredns resource. When you select a resource, you are in Structured view, by default. For some resource types, you see a Pods section in Structured view. This section lists the Pods managed by the workload. You can select any Pod listed to view information about the Pod. Not all resource types display information in Structured View. If you select Raw view in the top right corner of the page for the resource, you see the complete JSON response from the Kubernetes API for the resource.

    • Select the Cluster group and then select the Nodes resource type. You see a list of all nodes in your cluster. The nodes can be any Amazon EKS node type. This is the same list that you see in the Nodes section when you select the Compute tab for your cluster. Select a node resource from the list. In Structured view, you also see a Pods section. This section shows you all Pods running on the node.

Required permissions

To view the Resources tab and Nodes section on the Compute tab in the AWS Management Console, the IAM principal that you’re using must have specific minimum IAM and Kubernetes permissions. Complete the following steps to assign the required permissions to your IAM principals.

  1. Make sure that the eks:AccessKubernetesApi, and other necessary IAM permissions to view Kubernetes resources, are assigned to the IAM principal that you’re using. For more information about how to edit permissions for an IAM principal, see Controlling access for principals in the IAM User Guide. For more information about how to edit permissions for a role, see Modifying a role permissions policy (console) in the IAM User Guide.

    The following example policy includes the necessary permissions for a principal to view Kubernetes resources for all clusters in your account. Replace 111122223333 with your AWS account ID.

    {
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "eks:ListFargateProfiles",
                "eks:DescribeNodegroup",
                "eks:ListNodegroups",
                "eks:ListUpdates",
                "eks:AccessKubernetesApi",
                "eks:ListAddons",
                "eks:DescribeCluster",
                "eks:DescribeAddonVersions",
                "eks:ListClusters",
                "eks:ListIdentityProviderConfigs",
                "iam:ListRoles"
            ],
            "Resource": "*"
        },
        {
            "Effect": "Allow",
            "Action": "ssm:GetParameter",
            "Resource": "arn:aws:ssm:*:111122223333:parameter/*"
        }
    ]
}

    To view nodes in connected clusters, the Amazon EKS connector IAM role should be able to impersonate the principal in the cluster. This allows the Connect a Kubernetes cluster to an Amazon EKS Management Console with Amazon EKS Connector to map the principal to a Kubernetes user.

  2. Create a Kubernetes rolebinding or clusterrolebinding that is bound to a Kubernetes role or clusterrole that has the necessary permissions to view the Kubernetes resources. To learn more about Kubernetes roles and role bindings, see Using RBAC Authorization in the Kubernetes documentation. You can apply one of the following manifests to your cluster that create a role and rolebinding or a clusterrole and clusterrolebinding with the necessary Kubernetes permissions:

    View Kubernetes resources in all namespaces

    • The group name in the file is eks-console-dashboard-full-access-group. Apply the manifest to your cluster with the following command:

      kubectl apply -f https://s3.us-west-2.amazonaws.com/amazon-eks/docs/eks-console-full-access.yaml
    View Kubernetes resources in a specific namespace

    • The namespace in this file is default. The group name in the file is eks-console-dashboard-restricted-access-group. Apply the manifest to your cluster with the following command:

      kubectl apply -f https://s3.us-west-2.amazonaws.com/amazon-eks/docs/eks-console-restricted-access.yaml

      If you need to change the Kubernetes group name, namespace, permissions, or any other configuration in the file, then download the file and edit it before applying it to your cluster:

      1. Download the file with one of the following commands:

        curl -O https://s3.us-west-2.amazonaws.com/amazon-eks/docs/eks-console-full-access.yaml
        curl -O https://s3.us-west-2.amazonaws.com/amazon-eks/docs/eks-console-restricted-access.yaml

      2. Edit the file as necessary.

      3. Apply the manifest to your cluster with one of the following commands:

        kubectl apply -f eks-console-full-access.yaml
        kubectl apply -f eks-console-restricted-access.yaml

  3. Map the IAM principal to the Kubernetes user or group in the aws-auth ConfigMap. You can use a tool such as eksctl to update the ConfigMap or you can update it manually by editing it.

    Important

    We recommend using eksctl, or another tool, to edit the ConfigMap. For information about other tools you can use, see Use tools to make changes to the aws-authConfigMap in the Amazon EKS best practices guides. An improperly formatted aws-auth ConfigMap can cause you to lose access to your cluster.

Edit with eksctl

  1. You need version 0.190.0 or later of the eksctl command line tool installed on your device or AWS CloudShell. To install or update eksctl, see Installation in the eksctl documentation.

  2. View the current mappings in the ConfigMap. Replace my-cluster with the name of your cluster. Replace region-code with the AWS Region that your cluster is in.

    eksctl get iamidentitymapping --cluster my-cluster --region=region-code

    An example output is as follows.

    ARN                                                                                             USERNAME                                GROUPS                          ACCOUNT
arn:aws:iam::111122223333:role/eksctl-my-cluster-my-nodegroup-NodeInstanceRole-1XLS7754U3ZPA    system:node:{{EC2PrivateDNSName}}       system:bootstrappers,system:nodes

  3. Add a mapping for a role. This example assume that you attached the IAM permissions in the first step to a role named my-console-viewer-role. Replace 111122223333 with your account ID.

    eksctl create iamidentitymapping \
    --cluster my-cluster \
    --region=region-code \
    --arn arn:aws:iam::111122223333:role/my-console-viewer-role \
    --group eks-console-dashboard-full-access-group \
    --no-duplicate-arns
    Important

    The role ARN can’t include a path such as role/my-team/developers/my-role. The format of the ARN must be arn:aws:iam::111122223333:role/my-role . In this example, my-team/developers/ needs to be removed.

    An example output is as follows.

    [...]
2022-05-09 14:51:20 [ℹ]  adding identity "arn:aws:iam::111122223333:role/my-console-viewer-role" to auth ConfigMap

  4. Add a mapping for a user. IAM best practices recommend that you grant permissions to roles instead of users. This example assume that you attached the IAM permissions in the first step to a user named my-user. Replace 111122223333 with your account ID.

    eksctl create iamidentitymapping \
    --cluster my-cluster \
    --region=region-code \
    --arn arn:aws:iam::111122223333:user/my-user \
    --group eks-console-dashboard-restricted-access-group \
    --no-duplicate-arns

    An example output is as follows.

    [...]
2022-05-09 14:53:48 [ℹ]  adding identity "arn:aws:iam::111122223333:user/my-user" to auth ConfigMap

  5. View the mappings in the ConfigMap again.

    eksctl get iamidentitymapping --cluster my-cluster --region=region-code

    An example output is as follows.

    ARN                                                                                             USERNAME                                GROUPS                                  ACCOUNT
arn:aws:iam::111122223333:role/eksctl-my-cluster-my-nodegroup-NodeInstanceRole-1XLS7754U3ZPA    system:node:{{EC2PrivateDNSName}}       system:bootstrappers,system:nodes
arn:aws:iam::111122223333:role/my-console-viewer-role                                                                                   eks-console-dashboard-full-access-group
arn:aws:iam::111122223333:user/my-user                                                                                                  eks-console-dashboard-restricted-access-group

Edit ConfigMap manually

For more information about adding users or roles to the aws-auth ConfigMap, see Add IAM principals to your Amazon EKS cluster.

  1. Open the aws-auth ConfigMap for editing.

    kubectl edit -n kube-system configmap/aws-auth

  2. Add the mappings to the aws-auth ConfigMap, but don’t replace any of the existing mappings. The following example adds mappings between IAM principals with permissions added in the first step and the Kubernetes groups created in the previous step:

    • The my-console-viewer-role role and the eks-console-dashboard-full-access-group.

    • The my-user user and the eks-console-dashboard-restricted-access-group.

      These examples assume that you attached the IAM permissions in the first step to a role named my-console-viewer-role and a user named my-user. Replace 111122223333 with your AWS account ID.

      apiVersion: v1
data:
mapRoles: |
  - groups:
    - eks-console-dashboard-full-access-group
    rolearn: arn:aws:iam::111122223333:role/my-console-viewer-role
    username: my-console-viewer-role
mapUsers: |
  - groups:
    - eks-console-dashboard-restricted-access-group
    userarn: arn:aws:iam::111122223333:user/my-user
    username: my-user
      Important

      The role ARN can’t include a path such as role/my-team/developers/my-console-viewer-role. The format of the ARN must be arn:aws:iam::111122223333:role/my-console-viewer-role . In this example, my-team/developers/ needs to be removed.

  3. Save the file and exit your text editor.
