 Updating managed add-ons 

The versions of each managed add-on are tested by IBM Cloud and approved for use in IBM Cloud Kubernetes Service. To update the components of an add-on to the most recent version supported by IBM Cloud Kubernetes Service, use the following steps.

Review the following links for specific update steps for each add-on.



* [ALB OAuth Proxy](https://cloud.ibm.com/docs/containers?topic=containers-comm-ingress-annotationsupgrading-alb-oauth-proxy-add-on)

 Reviewing add-on states and statuses 

You can check the health state and status of a cluster add-on by running the following command.

ibmcloud ks cluster addon ls -c <cluster_name_or_ID>

Example output

Name Version Health State Health Status
debug-tool 2.0.0 normal Addon Ready
istio 1.4 - Enabling

The Health State reflects the lifecycle of the add-on components. Each state is described in the following table.

* CLI







 Enabling the cluster autoscaler add-on in your cluster 

You can enable the add-on from the console or the command the line.



 Enabling the cluster autoscaler add-on from the console 



1. From the [IBM Cloud Kubernetes Service cluster dashboard](https://cloud.ibm.com/kubernetes/clusters), select the cluster where you want to enable autoscaling.
2. On the Overview page, click Add-ons.
3. On the Add-ons page, locate the Cluster Autoscaler add-on and click Install







 Enabling the cluster autoscaler add-on from the CLI 



1. Enable the cluster-autoscaler add-on by running the following command.

ibmcloud ks cluster addon enable cluster-autoscaler --cluster <cluster_name>

Example output

Enabling add-on cluster-autoscaler for cluster <cluster_name>...
The add-on might take several minutes to deploy and become ready for use.
OK
2. Verify that the add-on is installed and Ready.

ibmcloud ks cluster addon ls --cluster <cluster_name>

Example output

NAME Version Health State Health Status
cluster-autoscaler 1.0.1 normal Addon Ready



By default, no worker pools are enabled for autoscaling. To enable autoscaling on your worker pools, [update the cluster autoscaler ConfigMap to enable scaling for your worker pools](https://cloud.ibm.com/docs/containers?topic=containers-cluster-scaling-enable).





 Updating the cluster autoscaler add-on 

This topic applies only to the cluster autoscaler add-on.

If you upgrade your cluster to a version that isn't supported by the cluster autoscaler add-on, your apps might experience downtime and your cluster might not scale.

The cluster autoscaler has two types of updates.
