   Example: kubectl apply -f https://github.com/kedacore/keda/releases/latest/download/keda-full.yaml
2. Verify the KEDA pods are running:
   kubectl get pods -n <namespace>
   where <namespace> is the namespace where KEDA was installed.
   You should see KEDA-related pods running.

Solution - Upgrade

If a specific version of KEDA is required in your Kubernetes environment, it is most likely that the Helm Chart or the manifest file already exist. Contact your Operations or DevOps team to determine if there are company resources for upgrading KEDA BEFORE using either of the following procedures.

Procedure Using HELM Chart Package Manager

To upgrade KEDA:

1. Use the Helm Installation Guide to install Helm (if not already installed).
2. Do one of the following:

• • To upgrade to the latest version, use the following command:
    helm upgrade <release-name> kedacore/keda
    where <release-name> is the name of the KEDA release.
  • To upgrade to a specific version, use the following command:
    helm upgrade <release-name> kedacore/keda --version <version>
    where <release-name> is the name of the KEDA release and <version> is the version number of KEDA you want to upgrade to.

3. Verify the KEDA pods are running and have been updated:
   kubectl get pods -n <namespace>
   where <namespace> is the namespace where KEDA is installed.
   You should see KEDA-related pods running.

Procedure Using YAML Manifest

To upgrade KEDA:

1. Apply the appropriate manifests:
   kubectl apply -f https://github.com/kedacore/keda/releases/download/<version>/keda-full.yaml
   where <version> is the version number of KEDA you want to upgrade to.
2. Verify the KEDA pods are running and have been updated:
   kubectl get pods -n <namespace>
   where <namespace> is the namespace where KEDA is installed.
   You should see KEDA-related pods running.
