RFC for new badge type: deployments

[desktophero]

Idea

Add a badge type of deployments to consume the deployment status from Drone CI

Use Case

We're using deployments more and more. The current badge status approach is limited to type build and a query for branch. Exposing a badge of deployment would allow endpoints to consume and present a visualization of status for deployment x.

Possible Approach

The interface would be similar to the existing structure:

Status	Type	Filter	Example
Current	Branch	N/A	https://host/api/badges/org/repo/status.svg
Current	Branch	branch=foo	https://host/api/badges/org/repo/status.svg?branch=foo
New	Deployment	deployment=bar	https://host/api/badges/org/repo/status.svg?deployment=foo

Effort

The idea would be to refactor badges.go to allow deployments as a badge type.

Thoughts?

[PatWie]

Rather than using a special logic for deployment, having a badge for each build step would be sufficient.

pipeline:
  build:
  deploy:
  extra:

Getting a badge via https://host/api/badges/org/repo/status.svg?step=[deploy|build|extra]&branch=... would be great.
