Version: v2.5

Workload with NodePort Quick Start

Prerequisite

You have a running cluster with at least 1 node.

1. Deploying a Workload

You're ready to create your first Kubernetes workload. A workload is an object that includes pods along with other files and info needed to deploy your application.

For this workload, you'll be deploying the application Rancher Hello-World.

From the Clusters page, open the cluster that you just created.
From the main menu of the Dashboard, select Projects/Namespaces.
Open the Project: Default project.
Click Resources > Workloads.
Click Deploy.
Step Result: The Deploy Workload page opens.
Enter a Name for your workload.
From the Docker Image field, enter rancher/hello-world. This field is case-sensitive.
From Port Mapping, click Add Port.
From the As a drop-down, make sure that NodePort (On every node) is selected.
From the On Listening Port field, leave the Random value in place.
From the Publish the container port field, enter port 80.
Leave the remaining options on their default setting. We'll tell you about them later.
Click Launch.

Result:

Your workload is deployed. This process might take a few minutes to complete.
When your workload completes deployment, it's assigned a state of Active. You can view this status from the project's Workloads page.

2. Viewing Your Application

From the Workloads page, click the link underneath your workload. If your deployment succeeded, your application opens.

Attention: Cloud-Hosted Sandboxes

When using a cloud-hosted virtual machine, you may not have access to the port running the container. In this event, you can test Nginx in an ssh session on the local machine using Execute Shell. Use the port number after the : in the link under your workload if available, which is 31568 in this example.
