Service Token for Managed K8s Cluster

Published April 5, 2023 | Last modified November 20, 2024

Objective

This document provides instructions on how to create use a service token to access F5® Distributed Cloud Services Managed K8s cluster. To know more about Managed K8s, see Create and Deploy Managed K8s.

The service token is used for applications on the site-local network to access F5 Managed K8s cluster API server. This is useful in scenarios such as CI/CD deployments where, certificates need to be manually renewed periodically but certificates cannot be revoked and have shorter expiry duration.

F5 does not support revoking local Kubeconfig certificates of Managed K8s cluster and these certificates have short expiry duration of 14 days. In case of CI/CD deployments that require renewing certificates every 2 weeks, the using service token prevents impact to the deployments.

Using the instructions provided in this guide, you can create a service account using the local kubeconfig certificate of your Managed K8s cluster. You can then obtain the service token from the service account, apply it to the cluster role binding used in Managed K8s configuration, and access the Managed K8s server using the service token in the HTTP request header.

Note: Service token can be also created for a specific namespace and used for that namespace. The service token is applied using role and role binding. Instructions provided in this guide also cover applying the service account at namespace level.

Prerequisites

A valid Account is required.

Note: If you do not have an account, see Create an Account.

App Stack site with Managed K8s cluster.

Note: See Create and Deployed Managed K8s document for information on creating Managed K8s cluster. See Create App Stack Site for information on creating an App Stack site.

Create and Use Service Token in Managed K8s

Using service token for Managed K8s cluster requires you to first create a service account and obtain the token from it. After that, set the service account in any of the following Managed K8s configuration objects:

Role
Role Binding
Cluster Role
Cluster Role Binding

You can create service account and obtain the service token at cluster level or at a namespace level. The following chapters present instructions for both cases.

Use Service Token at Cluster Level

Do the following to create and use the service token at cluster level.

Create Service Account and Obtain Service Token

Do the following to create service account, and get service token:

Features can be viewed, and managed in multiple services.

This example shows Service Token setup in Distributed Apps.

Step 1: Log into F5® Distributed Cloud Console and download local kubeconfig of your Managed K8s.

Open F5® Distributed Cloud Console and select Distributed Apps.

Note: Homepage is role based, and your homepage may look different due to your role customization. Select All Services drop-down menu to discover all options. Customize Settings: Administration > Personal Management > My Account > Edit work domain & skills button > Advanced box > check Work Domain boxes > Save changes button.

Figure: Homepage

Note: Confirm Namespace feature is in correct namespace, drop-down selector located in upper-left corner. Not available in all services.

In the left navigation pane, select Applications > Virtual K8s.

Note: If options are not showing available, select Show link in Advanced nav options visible in bottom left corner. If needed, select Hide to minimize options from Advanced nav options mode.

Figure: Virtual K8s Kubeconfig file download

Select ... on your App Stack site enabled with managed K8s.
Select Kubeconfig to download the kubeconfig file to your computer.

Step 2: Create service account.

Set KUBECONFIG environment variable.


export KUBECONFIG=<kubeconfig-local>.yml

Copied!

Note: Replace <kubeconfig-local>.yml with the local kubeconfig file downloaded in Step 1.

Create service account. The following sample creates a service account with name my-pk8s-sa.


kubectl create serviceaccount my-pk8s-sa

Copied!

The above command returns the following output:

serviceaccount/my-pk8s-sa created

Copied!

Step 3: Obtain service token.

Enter the following command to print the service token for the service account created in previous step.

kubectl describe serviceaccount my-pk8s-sa

Copied!

The above command returns the following output. Note down the value of the token field.

Apply Service Account to Cluster Role Binding

You can either edit an existing cluster role binding that is associated with a managed K8s cluster or create a new cluster role binding object and apply it while creating or updating managed K8s cluster configuration. This example shows editing an existing cluster role binding object.

Log into F5® Distributed Cloud Console and perform the following:

Step 1: Start editing the cluster role binding.

Go to the Distributed Apps service.
Select Manage > Manage K8s > K8s Cluster Role Bindings.

Note: To change your skill level and/or work domains,

Select the Administration service

Select Personal Management > My Account

In the Work domains and skill level section, select Edit Work Domains & Skills

Select the appropriate skill domains and skill level

Select Save Changes

Figure: Local Kubeconfig of Managed K8s

Select ... > Manage Configuration for a cluster role binding object from the displayed list.
Select Edit Configuration in the upper right corner to enable changes.

Step 2: Apply service account to Subjects section.

Select Add Item in Subjects section.

Figure: Local Kubeconfig of Managed K8s

Select Service Account in Select Subject drop-down menu.
Enter Namespace.
Enter Name of the service account.
Select Apply to save the subject.

Apply Service Account to Role Binding

Do the following to create and apply the service account to role binding:

Step 1: Create a role configuration file.

Create a file with the role configuration in YAML format. The following is a sample configuration.

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  namespace: cmallam-ns1
  name: pod-reader
rules:
- apiGroups: [""] # "" indicates the core API group
  resources: ["pods", "deployments"]
  verbs: ["get", "watch", "list"]

Copied!

Note: Use a file editing utility such as vi or a text editor of your choice.

Step 2: Create a role binding configuration file.

Create a file with the role binding configuration in YAML format. The following is a sample configuration.

apiVersion: rbac.authorization.k8s.io/v1
# This role binding allows "jane" to read pods in the "cmallam-ns1" namespace.
# You need to already have a Role named "pod-reader" in that namespace.
kind: RoleBinding
metadata:
  name: read-pods
  namespace: cmallam-ns1
subjects:
# You can specify more than one "subject"
- kind: User
  name: "derek@example.com"#"name" is case sensitive
  apiGroup: rbac.authorization.k8s.io
- kind: User
  name: cmallam #"name" is case sensitive
  apiGroup: rbac.authorization.k8s.io
- kind: ServiceAccount
  name: my-pk8s-sa-cmallam-ns1
  namespace: cmallam-ns1
roleRef:
  # "roleRef" specifies the binding to a Role / ClusterRole
  kind: Role #this must be Role or ClusterRole
  name: pod-reader # this must match the name of the Role or ClusterRole you wish to bind to
  apiGroup: rbac.authorization.k8s.io

Copied!

Note: Enter the role name created in step 1 in the name field under the roleRef section of the above YAML file.

Step 3: Complete creating the role and role binding.

Enter the following commands to create role and role binding.

kubectl apply -f <role-yaml>.yml

kubectl apply -f <rolebinding-yaml>.yml

Copied!

On the managed K8s cluster, set the role with the role binding:


kubectl apply -f ~/work/features/vk8s/rolebindigs/role-example.yml -o=yaml
