HOT packages

Compose a package

Murano is an Application catalog which intends to support applications defined in different formats. As a first step to universality, support of a heat orchestration template was added. It means that any heat template could be added as a separate application into the Application Catalog. This could be done in two ways: manual and automatic.

Automatic package composing

Before uploading an application into the catalog, it should be prepared and archived. A Murano command line will do all preparation for you. Just choose the desired Heat Orchestration Template and perform the following command:

murano package-create –template wordpress/template.yaml

Note, that optional parameters could be specified:

–name:an application name, copied from a template by default
–logo:an application square logo, by default the heat logo will be used
–description:text information about an application, by default copied from a template
–author:a name of an application author
–output:a name of an output file archive to save locally
–full-name:a fully qualified domain name that specifies exact application location

Note

To performing this command python-muranoclient should be installed in the system

As the result, an application definition archive will be ready for uploading.

Manual package composing

Application package could be composed manually. Follow the 5 steps below.

  • Step 1. Choose the desired heat orchestration template

    For this example chef-server.yaml template will be used.

  • Step 2. Rename it to template.yaml

  • Step 3. Prepare an application logo (optional step)

    It could be any picture associated with the application.

  • Step 4. Create manifest.yaml file

    All service information about the application is contained here. Specify the following parameters:

    Format:defines an application definition format; should be set to Heat.HOT/1.0
    Type:defines a manifest type, should be set to Application
    FullName:a unique name which will be used to identify the application in Murano Catalog
    Description:text information about an application
    Author:a name of an application author or a company
    Tags:keywords associated with the application
    Logo:a name of a logo file for an application

    Take a look at the example:

    Format: Heat.HOT/1.0
Type: Application
FullName: io.murano.apps.Chef-Server
Name: Chef Server
Description: "Heat template to deploy Open Source CHEF server on a VM"
Author: Kate

Logo: logo.png

  • Step 5. Create a zip archive, containing the specified files: template.yaml, manifest.yaml, logo.png

Applications page looks like:

../../_images/chef_server.png

The configuration form, where you can enter template parameters, will be generated automatically and looks as follows:

../../_images/chef_server_form.png

After filling the form the application is ready to be deployed.
