Documentation

Overview

Package ccv3 represents a Cloud Controller V3 client.

These sets of packages are still under development/pre-pre-pre...alpha. Use at your own risk! Functionality and design may change without warning.

It is currently designed to support Cloud Controller API 3.0.0. However, it may include features and endpoints of later API versions.

For more information on the Cloud Controller API see https://apidocs.cloudfoundry.org/

Method Naming Conventions

The client takes a '<Action Name><Top Level Endpoint><Return Value>' approach to method names. If the <Top Level Endpoint> and <Return Value> are similar, they do not need to be repeated. If a GUID is required for the <Top Level Endpoint>, the pluralization is removed from said endpoint in the method name.

For Example:

Method Name: GetApplication
Endpoint: /v3/applications/:guid
Action Name: Get
Top Level Endpoint: applications
Return Value: Application

Method Name: GetServiceInstances
Endpoint: /v3/service_instances
Action Name: Get
Top Level Endpoint: service_instances
Return Value: []ServiceInstance

Method Name: GetSpaceServiceInstances
Endpoint: /v3/spaces/:guid/service_instances
Action Name: Get
Top Level Endpoint: spaces
Return Value: []ServiceInstance

Method Name: CreateApplicationTask
Endpoint: /v3/apps/:application_guid/task
Action Name: Post
Top Level Endpoint: apps
Return Value: []Task

Use the following table to determine which HTTP Command equates to which Action Name:

HTTP Command -> Action Name
POST -> Create
GET -> Get
PUT -> Update
DELETE -> Delete

Method Locations

Methods exist in the same file as their return type, regardless of which endpoint they use.

Error Handling

All error handling that requires parsing the error_code/code returned back from the Cloud Controller should be placed in the errorWrapper. Everything else can be handled in the individual operations. All parsed cloud controller errors should exist in errors.go, all generic HTTP errors should exist in the cloudcontroller's errors.go. Errors related to the individaul operation should exist at the top of that operation's file.
