Overview

Package service provides access to the service api facade. This facade contains api calls that are specific to services. As a rule of thumb, if the argument for an api requries a service name and affects only that service then the call belongs here.

func NewClient(st api.Connection) *Client

NewClient creates a new client for accessing the service api.

func (*Client) AddRelation

func (c *Client) AddRelation(endpoints ...string) (*params.AddRelationResults, error)

AddRelation adds a relation between the specified endpoints and returns the relation info.

func (*Client) AddUnits

func (c *Client) AddUnits(service string, numUnits int, placement []*instance.Placement) ([]string, error)

AddUnits adds a given number of units to a service using the specified placement directives to assign units to machines.

func (*Client) CharmRelations

func (c *Client) CharmRelations(service string) ([]string, error)

CharmRelations returns the service's charms relation names.

func (*Client) Deploy

func (c *Client) Deploy(args DeployArgs) error

type DeployArgs

type DeployArgs struct {
	// CharmID identifies the charm to deploy.
	CharmID charmstore.CharmID
	// ServiceName is the name to give the service.
	ServiceName string
	// Series to be used for the machine.
	Series string
	// NumUnits is the number of units to deploy.
	NumUnits int
	// ConfigYAML is a string that overrides the default config.yml.

	// created.
	Placement []*instance.Placement
	// Storage contains Constraints specifying how storage should be
	// handled.
	Storage map[string]storage.Constraints
	// EndpointBindings

	// unique ID of a pre-uploaded resources in storage.
	Resources map[string]string
}

DeployArgs holds the arguments to be sent to Client.ServiceDeploy.

type SetCharmConfig

type SetCharmConfig struct {
	// ServiceName is the name of the service to set the charm on.
