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​

Add a Helm Chart to an App Profile​

  1. Log in to Palette.

  2. From the User Menu, select Switch to App Mode.

  3. Select App Profiles from the left Main Menu, and click on the New App Profile button.

  4. Provide the following basic information for your app profile and click Next.

    ParameterDescription
    App Profile NameA custom name for the app profile.
    VersionAn 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.
    DescriptionUse the description to provide context about the profile.
    TagAssign 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 or region.

    To learn how to create multiple profile versions that use the same name, check out Version an App Profile.

  5. Select Helm to start configuring your app profile.

  6. Use the drop-down Menus to select a Helm registry, chart, and version.

  1. You can add manifests to the app profile. To do this, click on Add Manifests and provide the manifest name.

    warning

    When adding a manifest-type layer to an app profile, make sure you specify a namespace. Otherwise, the manifest deployment will be deployed to the Default namespace.

  2. You can add services to the app profile as needed. To do this, click + next to the Configure tier pane. To rearrange layers in the profile, select a service and drag it up or down in the pane. Each service becomes a layer in the profile stack in the order displayed in this pane.

  3. When you have provided the required configuration information, click Review.

Your app profile is now created using a Helm chart and can be deployed.

Validate​

Use the following steps to validate that your app profile is available and ready for use.

  1. Log in to Palette.

  2. From the User Menu, switch to App Mode.

  3. Click on App Profiles in the left Main Menu, and select the app profile you created to review its details.

  4. Hover your cursor over each profile layer to learn more about them, including the service name, version, and registry.

    Use the tool-tip that displays when you select a layer to gather information required for creating Terraform templates for app profiles. Check out our Terraform registry for Application Profiles.

  5. Deploy your application to a virtual cluster to verify all the required configurations and dependencies are correct. Review Create and Manage Apps to learn how to deploy an app to a virtual cluster. Check out the Deploy an Application using Palette Dev Engine tutorial for a more in-depth guide.
