Drone starlark does not support the runner plugins

Drone Bugs
#1

Hola crew!

Drone starlark does not appear to allow generating .yamls for the pluggable runners (such as kubernetes or ssh). For example,

def main(ctx): 
    return {
        "kind": "pipeline",

        "type": "ssh",
        "name": "poc",
        
        # Currently, this must be ported across manually to .drone.yml. See
        # https://github.com/drone/drone-yaml/issues/49
        "server": {
            "host": "127.0.0.1",
            "user": "ubuntu",
            "ssh_key": {
                "from_secret": "ssh_key"
            }
        },
        "steps": [{
            "name": "salt-sync",
            "commands": [
                "sudo salt \* saltutil.sync_all"
            ]
        }]
    }

produces

---
kind: pipeline
type: ssh
name: poc

platform:
  os: linux
  arch: amd64

steps:
- name: salt-sync
  commands:
  - sudo salt \* saltutil.sync_all
...

(it’s missing the host bit)

the local starlark command only supports the docker pipeline type at the moment, but you can work around this by disabling formatting:

drone starlark --stdout --format=false

Oh! That works. Still, I kind of like my yaml (that output being json). Can you give some hint as to what I might look at if I was to try and implement this feature?
