Use On-Demand

Apps are a way for admins to package applications and scripts in consumable packages. These applications can then be deployed into clusters, namespaces, or tenant clusters managed by vCluster Platform. This can be a useful tool for adding pre-defined applications to newly connected clusters, or to newly created namespaces or tenant clusters that are not already using a template that includes Apps.

Install apps on a tenant cluster

Tenant clusters combined with Apps are a great way to create repeatable, pre-packaged development, testing, or even production environments. Once an App has been created in the vCluster Platform instance, it can be installed into any tenant cluster -- either at time of creation, or into existing tenant clusters. This gives administrators the capability to create fully populated development, test, or even production, environments in a single easy to manage package.

8. For each application that you added to the template, you can configure the default namespace, and any parameters supplied by the application. For Helm applications, you can also configure the Helm release-name.

9. Finish configuring anything else you'd like on your tenant cluster, then click the button.
