Upgrade Guide

This document describes how to upgrade the serving-operator to an expected version.

Backup precaution

As an administrator, you are recommended to save the content of the custom resource for serving-operator before upgrading your operator. Make sure that you know the name and the namespace of your CR, and use the following command to save the CR in a file called serving_operator_cr.yaml:

For the version v0.10.0 or later:

kubectl get KnativeServing <cr-name> -n <namespace> -o=yaml > serving_operator_cr.yaml

Replace <cr-name> with the name of your CR, and <namespace> with the namespace.

One version of serving-operator installs only one specific version of Knative Serving. With your operator successfully upgraded, your Knative Serving is upgraded as well.

v0.10.0, v0.11.x -> v0.12.0

Both of v0.10 and v0.11 versions are able to upgrade to the version v0.12.0 by running the following command:

kubectl apply -f https://github.com/knative/serving-operator/releases/download/v0.12.0/serving-operator.yaml
