Create vK8s Workload

Published April 5, 2023 | Last modified November 12, 2026

Objective

This guide provides instructions on how to create, deploy, and advertise a virtual Kubernetes (vK8s) workload with F5® Distributed Cloud Services vK8s in F5® Distributed Cloud Console (Console). Distributed Cloud Services provide mechanisms to easily deploy applications across a global network and make them available closer to users in major metro markets. To learn more about how Distributed Cloud Services distribute application deployment, see Distributed Application Management.

To learn more about vK8s workloads, see vK8s Workload.

Using guided creation for vK8s Workload, you can create the following types of workloads:

Simple Service
Service
Stateful Service
Job

Using the instructions provided in this guide, you can perform the following:

Create a simple service that is deployed on all Regional Edge (RE) sites and advertised on the Internet using an HTTP load balancer.
Create a stateful service that is deployed on a Customer Edge (CE) site and advertised locally on the site.

Prerequisites

The following prerequisites apply:

An F5 Distributed Cloud Account. If you do not have an account, see Getting Started with Console.
To deploy applications on your sites, first create a vK8s object per the instructions in the Create Virtual K8s Object document.
A CE site for deploying the stateful service application on CE sites. If you do not have a site, create a site using the instructions included in the Site Management guides.

Configuration

The configuration option to create the vK8s Workload guides you through the steps for the required configuration. This document covers each guided step and explains the required actions performed for each step.

Configuration Sequence

Deploying applications on the Distributed Cloud Services requires you to perform the following sequence of steps:

Phase	Description
Deploy Workload to vK8s	Add vK8s Workload to the created vK8s object.
Verify the Workload Status	Check the workload status.

Simple Service

Deploy Workload (Simple Service) to vK8s

Step 1: Navigate to the vK8s Workload configuration.

Log into Console.
Select Distributed Apps.
Select your application namespace or create one where your application needs to be deployed.
Select Applications > Virtual K8s.
Select the vK8s object to open its dashboard.

Note: If you did not previously create the vK8s object, then the Add Virtual K8s option will be available to create vK8s.

Select the Workloads tab.

Step 2: Start the workload creation process.

Select Add VK8s Workload to open the workload creation form.

Figure: Start Workload Creation

In the Metadata section, enter a name for this workload.
In the Select Type of Workload section, select an option from the Select Type of Workload menu. The following options are supported:
- Select Simple service on all REs to create a simple service.
- Select Service to create a service.
- Select Stateful Service to create a stateful service.
- Select Job to create a job.

This example configures a simple service.

Step 3: Configure Simple Service.

Perform the following:

Step 3.1 Configure container.

Select Configure.
In the Name field, enter a name for the container.
In the Image Name field, enter a name. The Image Name is the name of the Docker image to use and specified in the <path>:<imagetag> format.

Note: If your registry is a Docker Hub, then the value of the Image Name field should be specified in the docker.io/<path>:<imagetag> format.

From the Select Container Registry menu, select the type of registry used: Public Registry or Private Registry.

To configure more options, select Show Advanced Fields.
Select Apply.

Step 3.2 Optionally, add configuration parameters.

Select from the left menu or scroll to the Configuration Parameters section.
Select Add Item.

Enter the Name and Value for the environment variable.
Select Apply.

Step 3.3 Configure the advertise options.

Select from the left menu or scroll to the Advertise Options section.
From the Select Advertise Options menu, select Domains and Service Port from the options.
In the Service Port field, enter the port number on which the container will listen.
In the List of Domain field, enter a domain.

Step 4 Configure persistent storage.

By default, this option is set to Disabled.

In the Persistence section, select Enabled from the Persistent Storage menu.
Configure the settings and select Apply to save the persistent storage settings.

Step 5 Complete creating the simple service workload.

Select Apply to go back to the workload configuration page.
Select Save and Exit to finish creating the workload.

In the Workloads tab, check that the workload was created.

Verify the Workload (Simple Service) Status

Select the Deployments tab and verify that the deployment with the same name as the workload is running.

Stateful Service

Deploy Workload (Stateful Service) to vK8s

Step 1: Navigate to the vK8s Workload configuration.

Log into Console.
Select Distributed Apps.
Select your application namespace or create one where your application needs to be deployed.
Select Applications > Virtual K8s.
Select the vK8s object to open its dashboard.

Note: If you did not previously create the vK8s object, then the Add Virtual K8s option will be available to create vK8s.

Select the Workloads tab.

Step 2: Start the workload creation process.

Select Add vK8s workload to open the workload creation form.

Figure: Start Workload Creation

In the Metadata section, enter a name for this workload.
In the Select Type of Workload section, select an option from the Select Type of Workload menu. The following options are supported:
- Select Simple service on all REs to create a simple service.
- Select Service to create a service.
- Select Stateful Service to create a stateful service.
- Select Job to create a job.
Select Stateful Service and then select Configure.
