Murano Charm

To add a service to Openstack provide a catalogue of applications deployable on Openstack.

Problem Description

To provide UI and API which allows to compose and deploy composite environments on the Application abstraction level and then manage their lifecycle. The Service should be able to orchestrate complex circular dependent cases in order to setup complete environments with many dependent applications and services. However, the actual deployment itself will be done by the existing software orchestration tools (such as Heat), while the Murano project will become an integration point for various applications and services.

Proposed Change

One new charm - Murano with corresponding tests and QA CI/setup.

The new Murano charm should include, as a minimum, the following features:

• Deployable in a highly available configuration
• Allow clients and services to interact using SSL encryption
• Charm progress displayed via workload status

Alternatives

Jobs could scheduled manually via cron on each machine.

Work Items

Provide Murano charm

• Create skeleton charm layer based on OpenStack base layer and available interface layers to deploy Murano.
• Add support for upgrading Murano
• Add config option and accompanying support for upgrades via action-managed-upgrade.
• Add support for deploying Murano in a highly available configuration
• Add support for the Murano to display workload status
• Add support SSL endpoints
• Charm should have unit and functional tests.

Mojo specification deploying and testing Murano

• Write Mojo spec for deploying murano in an HA configuration and testing creation of jobs.

Repositories

A new git repository will be required for the Murano charm:

https://git.openstack.org/openstack/charm-murano

Documentation

The Murano charm should contain a README with instructions on deploying the charm. A blog post is optional but would be a useful addition.

Security

No additional security concerns.

Testing

Code changes will be covered by unit tests; functional testing will be done using a combination of Amulet, Bundle tester and Mojo specification.
