Parameter Templates
===============================================

You can use the parameter template to override Helm\* chart values when deploying an application. These
values are profile-specific and are typically known to the developer. You may need to change some overridden values, or define confidential values as secret, before deployment.

For example, if your application needs a valid IP address to run, you can create a parameter template for the IP address so that unless you provide the IP address, the application will not be deployed.

To add a parameter template:

.. figure:: images/param_template.png
   :scale: 70 %
   :alt: Add Parameter Template

1. Populate the **Chart values** field when you add an application profile.
#. In Advanced Settings, select **Yes** to allow users to override selected profile values at deployment time.
#. Click on the add button to add a parameter template. **Note:** you can only select a value that is already in the chart values field that you populated in step 1.
#. Once completed, click "Add Profile" to create and add the profile.
