If you deployed the previous version of Tanzu Kubernetes Grid in an Internet-restricted environment, do the following steps on a machine with an Internet connection.

  1. Download and install the new version of the Tanzu CLI. See Download and Install the Tanzu CLI and Other Tools.

  2. Perform the steps in Prepare to Upgrade Clusters on vSphere to deploy the new base OS image OVA files.

  3. Perform the steps in Deploying Tanzu Kubernetes Grid in an Internet-Restricted Environment to run the gen-publish-images.sh and publish-images.sh scripts.

If you still have the publish-images.sh script from when you deployed the previous version of Tanzu Kubernetes Grid, you must regenerate it by running gen-publish-images.sh before you run publish-images.sh.

Running gen-publish-images.sh updates publish-images.sh so that it pulls the correct versions of the components for the new version of Tanzu Kubernetes Grid and pushes them into your local private Docker registry.

The gen-publish-images.sh script obtains the correct versions of the components from the YAML files that are created in the ~/.tanzu/tkg/bom folder when you first run a tanzu CLI command with a new version of Tanzu Kubernetes Grid.
