Class: CFoundry::V2::App
- Includes:
- UploadHelpers
- Defined in:
- lib/cfoundry/v2/app.rb
Overview
Class for representing a user’s application on a given target (via Client).
Does not guarantee that the app exists; used for both app creation and retrieval, as the attributes are all lazily retrieved. Setting attributes does not perform any requests; use #update! to commit your changes.

#health ⇒ Object
Determine application health.
If all instances are running, returns “RUNNING”. If only some are started, returns the precentage of them that are healthy.
Otherwise, returns application’s status.

- path
-
A path pointing to either a directory, or a .jar, .war, or .zip file.
If a .vmcignore file is detected under the given path, it will be used to exclude paths from the payload, similar to a .gitignore.
- check_resources
-
If set to ‘false`, the entire payload will be uploaded without checking the resource cache.
Only do this if you know what you’re doing.
