Host specific tasks: on() and select() in YAML?

[wivaku]

I can use on() and select() to run specific tasks on specific hosts.

Can I configure tasks like that in a YAML based setup?

While checking the JSON Schema, I noticed select is available. But it expects a string, which based on my test expects a single hostname (as opposed to the PHP version where you provide a filter, e.g. $hosts = select('type=web,env=prod');)

So e.g.

hosts:
  production:
    # ...
  staging:
    # ...

tasks:
  mytask:
    - select: production
    # - cd: ...
    # - run: ...

The schema lists as possible properties:

• string: cd, run, run_locally, desc
• object: upload, download
• boolean: once, hidden
• number: limit
