User Story

As a developer working on an existing project, I want to be able to have a docker-compose reference in devfile which allows me to provide an existing docker-compose file for the application definition

Acceptance Criteria

• A new component in devfile API for docker-compose file reference
• validation need to be done for the new component
• new tests for testing the new component
• documentation for usage and limitation

Link to PR: #1134
Completed creating the compose component. Currently troubleshooting validation code.

Based on the discussions on the Devfile Community call on 6/19, more documentation is needed to document the usage and the limitations of the API documentation. Note that if the limitation is coming from Kcompose, we can link the doc to the Kcompose instead of duplicating the information.
