1. Click on Add Cluster.
2. Choose a provider. In our example, we will use GKE. Some settings for other providers might be slightly different:

3. Enter a cluster name.

If you have your GCP service account JSON file that we saved previously, skip to step 10.

4. From the GCP navigation menu, go to IAM and click on the Service accounts link.
5. Click on Create Service Account.
6. Enter a service account name and click Create.
7. Add the required minimum permissions; that is, Compute Viewer, Viewer, Kubernetes Engine Admin, and Service Account User, and click Continue.
8. Click on Create Key. Use JSON as the key type in order to save your service account.
9. On the Rancher UI, click on Read from a file and load the service account JSON file you saved previously.
10. Customize the Cluster Options as needed; otherwise, use the default settings and click on Create to deploy your Kubernetes cluster:

Your cluster will be listed and ready to be managed immediately on your Rancher dashboard.
