Manifest to launch flask app in Cloud.gov

[krishnasanaka]

User Story

In order to add new harvest sources to our Harvest DB, datagovteam wants to add a new Flask app to handle basic CRUD of Harvest Source configs, and to kick off harvest jobs.

Links:

• Datagov Harvest Orchestrator repo: https://github.com/GSA/datagov-harvest-orchestrator
• Tutorial for adding a basic form to your Flask app: https://www.digitalocean.com/community/tutorials/how-to-use-flask-sqlalchemy-to-interact-with-databases-in-a-flask-application
• Previous work done on Flask / DB integration: Create Basic Flask Harvest Administration App #4619

Acceptance Criteria

[ACs should be clearly demoable/verifiable whenever possible. Try specifying them using BDD.]

• GIVEN I have created a Flask app and added it to the repository above
  AND that app has imported datagov-harvesting-logic as a dependency
  AND I have followed the pattern outlined in the links above to develop a form to update Harvest Source
  WHEN I save a new Harvest Source with a valid config then I expect it to post to the Harvest DB.

• GIVEN I call the route {url}/harvests/{id}
  THEN I expect to see the details for the harvest source with the corresponding id.

• GIVEN I call the route {url}/harvests/ with no corresponding ID
  THEN I expect to see a list of all harvest sources in the DB

Security Considerations (required)

[Any security concerns that might be implicated in the change. "None" is OK, just be explicit here!]

Sketch

• Add manifest to launch this as an app in Cloud.gov with an http health check
• Add a route so that this is accessible from the public internet
• Enable basic auth so that this is locked down by username/password
• Create new harvest source config and confirm it is viewable by using the CF Service Connect plugin to examine the DB tables
