Add a Helm Chart
You can extend the list of available Palette Dev Engine services with custom Helm charts. Use the following steps to create an app profile that contains a Helm chart.
A tutorial is available to help you learn how to use Palette Dev Engine by deploying an application. Check out Deploy an Application using Palette Dev Engine to get started with Palette Dev Engine.
Prerequisites
- A Spectro Cloud account.
Add a Helm Chart to an App Profile
-
Log in to Palette.
-
From the User Menu, select Switch to App Mode.

Select App Profiles from the left Main Menu, and click on the New App Profile button.
-
Provide the following basic information for your app profile and click Next.
Parameter Description App Profile Name A custom name for the app profile. Version An optional version number for the new app profile. You only need to specify a version if you create multiple versions of a profile using the same profile name. Default: 1.0.0
.Description Use the description to provide context about the profile. Tag Assign any desired profile tags. Tags propagate to the Virtual Machines (VMs) deployed in the cloud or data center environment when apps are created from this app profile. Example: owner
orregion
.To learn how to create multiple profile versions that use the same name, check out Version an App Profile.
-
Select Helm to start configuring your app profile.
-
Use the drop-down Menus to select a Helm registry, chart, and version.
-
You can add manifests to the app profile. To do this, click on Add Manifests and provide the manifest name.
