Applications
============

An application in |software_prod_name| is defined by a single Helm\* chart with predefined runtime configurations or profiles.
The Helm chart must fulfill the following criteria, to be deployed and managed using |software_prod_name|\ :

* Deployable on CNCF-certified Kubernetes\* version v1.27.
* All Helm charts, including applications and dependencies, are stored in the Helm or OCI registry and can be downloaded through the network.
* Deployable using Helm install.
* Upgradable using Helm upgrade.
* Removable using Helm delete.
* Re-deployable using Helm install after delete; no manual cleanup is required.
* Use the *helm lint* command to check if the chart is well-formed.
* All Kubernetes resource creation and updates are done through the Helm chart. However, Intel does not recommend dynamic resource creation or update because this could lead to unexpected results.

See :doc:`/developer_guide/application_developer_workflow/deployment-helm/index`
for more Helm chart Best Practices.

View Applications
~~~~~~~~~~~~~~~~~

To view the **Applications** page, click the **Deployments** tab and then click **Applications** on the left menu.
On the **Applications** page, you can view the list of applications and the available registries.
You can search for applications and registries using the search bar at the top of the page. The other actions you can perform from this page are editing, viewing details, and deleting an application.

Applications are partitioned into two tabs:

*   **Applications** - Displays the list of user provided applications that are available for deployment.
    (The list is empty until a user adds an application)
*   **Extensions** - Displays the list of system provided extensions that are available for deployment.
    (The list is populated with many preconfigured applications. You cannot add or delete applications from this list).
