Creating an Application Template

The configuration options for an application can be extracted from a catalog and viewed, saved to a file, or edited directly. To view the configuration, you generate a template. To save the template to a file to use for an installation, redirect the output to a file.

To edit a template interactively, set the EDITOR environment variable to the location of a text editing program. For example:

export EDITOR=/usr/bin/vim

Use the ocne application template command to create an application template. The syntax is:

ocne application template 
{-c|--catalog} name 
[{-i|--interactive}]
{-N|--name} name 
[{-v|--version} version] 

For more information on the syntax options, see Oracle Cloud Native Environment: CLI.

Examples:

To display a template for an application named prometheus in the default catalog:

ocne application template --name prometheus

To save a template for an application to a file, pipe the output to a file:

ocne application template --name prometheus > mytemplate.yaml

To save a template for an application and edit it interactively:

ocne application template --name prometheus --interactive

The template is saved to a local file using the naming convention application_name-values.yaml.

The following steps show you how to edit an application template in the UI before proceeding with the installation:

  1. In the navigation menu, select Apps.

    The Apps section expands to display further options in the navigation menu.

  2. Select Oracle Cloud Native Environment Application Catalog.

    The Applications page is displayed, listing the applications available in the catalog.

  3. Select the Install option for the application whose template you're creating.

    A dialog box appears with an edit box containing the application template for application you selected. The dialog also contains mandatory fields to configure the installation.
    1. Edit the application template as required.

    2. Complete the mandatory fields: Release Name, Namespaces, Versions, Release Description

  4. Select Install.

    The dialog is dismissed, and on-screen messages are displayed to confirm the installation request has been successfully submitted and completed.
