{: #managed-addons}
Quickly add extra capabilities and open-source technologies to your cluster with managed add-ons. {: shortdesc}
What are managed add-ons?
Managed {{site.data.keyword.containerlong_notm}} add-ons are an easy way to enhance your cluster with extra capabilities and open-source capabilities, such as Istio, Knative, Kubernetes Terminal, or {{site.data.keyword.block_storage_is_short}}. The version of the driver, plug-in, or open-source tool that you add to your cluster is tested by IBM and approved to be used in {{site.data.keyword.containerlong_notm}}.
The managed add-ons that you can install in your cluster depend on the type of cluster, the container platform, and the infrastructure provider that you choose. {: note}
How does the billing and support work for managed add-ons?
Managed add-ons are fully integrated into the {{site.data.keyword.cloud_notm}} support organization. If you have a question or an issue with using the managed add-ons, you can use one of the {{site.data.keyword.containerlong_notm}} support channels. For more information, see Getting help and support.
If the tool that you add to your cluster incurs costs, these costs are automatically integrated and listed as part of your {{site.data.keyword.containerlong_notm}} billing. The billing cycle is determined by {{site.data.keyword.cloud_notm}} depending on when you enabled the add-on in your cluster.
What limitations do I need to account for?
If you installed the container image security enforcer admission controller in your cluster, you cannot enable managed add-ons in your cluster.
{: #adding-managed-add-ons}
To enable a managed add-on in your cluster, you use the ibmcloud ks cluster addon enable command. When you enable the managed add-on, a supported version of the tool, including all Kubernetes resources are automatically installed in your cluster. Refer to the documentation of each managed add-on to find the prerequisites that your cluster must meet to install the managed add-on.
For more information about the prerequisites for each add-on, see:
{: #updating-managed-add-ons}
The versions of each managed add-on are tested by {{site.data.keyword.cloud_notm}} and approved for use in {{site.data.keyword.containerlong_notm}}. To update the components of an add-on to the most recent version supported by {{site.data.keyword.containerlong_notm}}, use the following steps. {: shortdesc}
- Check for update instructions that are specific to your managed add-on, such as Knative or Istio. If you do not find update instructions, continue with the next step.
- If your add-on does not have specific update instructions, select the cluster where you installed managed add-ons from your cluster dashboard.
- Select the Add-ons tab.
- From the actions menu, select Update to start updating the managed add-on. When the update is installed, the latest version of the managed add-on is listed on the cluster add-on page.
