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

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

HTTP Command -> Action Name
POST -> New
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.

	HREF string `json:"href"`

	// Meta contains additional metadata about the API.
	Meta struct {
		// Version of the API
		Version string `json:"version"`
	} `json:"meta"`
}

APILink represents a generic link from a response object.

	Title  string `json:"title"`
}

CCError represents a cloud controller error.

type CCErrorResponse

type CCErrorResponse struct {
	Errors []CCError `json:"errors"`
}

CCErrorResponse represents a generic Cloud Controller V3 error response.

type Client

type Client struct {
	APIInfo
	// contains filtered or unexported fields
}

Client can be used to talk to a Cloud Controller's V3 Endpoints.

func NewClient

func NewClient(appName string, appVersion string) *Client

NewClient returns a new Client.

func (*Client) GetApplicationTasks

func (client *Client) GetApplicationTasks(appGUID string, query url.Values) ([]Task, Warnings, error)

GetApplicationTasks returns a list of tasks associated with the provided application GUID. Results can be filtered by providing URL queries.

func (*Client) GetApplications

func (client *Client) GetApplications(query url.Values) ([]Application, Warnings, error)

GetApplications lists applications with optional filters.

func (*Client) Info

func (client *Client) Info() (APIInfo, ResourceLinks, Warnings, error)

Info returns back endpoint and API information from /v3.

func (*Client) NewTask

func (client *Client) NewTask(appGUID string, command string, name string) (Task, Warnings, error)

NewTask runs a command in the Application environment associated with the provided Application GUID.

func (*Client) TargetCF

func (client *Client) TargetCF(settings TargetSettings) (Warnings, error)

TargetCF sets the client to use the Cloud Controller specified in the configuration. Any other configuration is also applied to the client.

func (*Client) UpdateTask

func (client *Client) UpdateTask(taskGUID string) (Task, Warnings, error)

UpdateTask cancels a task.

func (*Client) WrapConnection

func (client *Client) WrapConnection(wrapper ConnectionWrapper)

WrapConnection wraps the current Client connection in the wrapper.

type ConnectionWrapper

type ConnectionWrapper interface {
	cloudcontroller.Connection
	Wrap(innerconnection cloudcontroller.Connection) cloudcontroller.Connection
}

ConnectionWrapper can wrap a given connection allowing the wrapper to modify all requests going in and out of the given connection.

type NewTaskBody

type NewTaskBody struct {
	Command string `json:"command"`
	Name    string `json:"name,omitempty"`
}

NewTaskBody represents the body of the request to create a Task.

type PaginatedResources

type PaginatedResources struct {
	Pagination struct {
		Next struct {
			HREF string `json:"href"`
		} `json:"next"`
	} `json:"pagination"`
	ResourcesBytes json.RawMessage `json:"resources"`
	// contains filtered or unexported fields
}

PaginatedResources represents a page of resources returned by the Cloud Controller.

func NewPaginatedResources

	// DialTimeout is the DNS timeout used to make all requests to the Cloud
	// Controller.
	DialTimeout time.Duration

	// SkipSSLValidation controls whether a client verifies the server's
	// certificate chain and host name. If SkipSSLValidation is true, TLS accepts
	// any certificate presented by the server and any host name in that
	// certificate for *all* client requests going forward.
	//
	// In this mode, TLS is susceptible to man-in-the-middle attacks. This should
	// be used only for testing.
	SkipSSLValidation bool

	// URL is a fully qualified URL to the Cloud Controller API.
	URL string
}

TargetSettings represents configuration for establishing a connection to the Cloud Controller server.
