Functions ¶
func Manifold ¶
func Manifold(config ManifoldConfig) dependency.Manifold
Manifold creates a manifold that runs a CAAS unit provisioner. See the ManifoldConfig type for discussion about how this can/should evolve.
Types ¶
type ApplicationGetter ¶
type ApplicationGetter interface {
WatchApplications() (watcher.StringsWatcher, error)
WatchApplication(appName string) (watcher.NotifyWatcher, error)
ApplicationConfig(string) (application.ConfigAttributes, error)
DeploymentMode(string) (caas.DeploymentMode, error)
WatchApplicationScale(string) (watcher.NotifyWatcher, error)
ApplicationScale(string) (int, error)
}
ApplicationGetter provides an interface for watching for the lifecycle state changes (including addition) of applications in the model, and fetching their details.
type ApplicationUpdater ¶
type ApplicationUpdater interface {
UpdateApplicationService(arg params.UpdateApplicationServiceArg) error
ClearApplicationResources(appName string) error
}
ApplicationUpdater provides an interface for updating Juju applications from changes in the cloud.
type CharmGetter ¶
type CharmGetter interface {
ApplicationCharmInfo(appName string) (*charmscommon.CharmInfo, error)
}
type Client ¶
type Client interface {
ApplicationGetter
ApplicationUpdater
ProvisioningInfoGetter
LifeGetter
UnitUpdater
ProvisioningStatusSetter
CharmGetter
}
Client provides an interface for interacting with the CAASUnitProvisioner API. Subsets of this should be passed to the CAASUnitProvisioner worker.
type Config ¶
type Config struct {
ApplicationGetter ApplicationGetter
ApplicationUpdater ApplicationUpdater
ServiceBroker ServiceBroker
ContainerBroker ContainerBroker
ProvisioningInfoGetter ProvisioningInfoGetter
ProvisioningStatusSetter ProvisioningStatusSetter
LifeGetter LifeGetter
UnitUpdater UnitUpdater
CharmGetter CharmGetter
Logger Logger
}
Config holds configuration for the CAAS unit provisioner worker.
type ContainerBroker ¶
type ContainerBroker interface {
Provider() caas.ContainerEnvironProvider
WatchOperator(string) (watcher.NotifyWatcher, error)
Operator(string) (*caas.Operator, error)
WatchUnits(appName string, mode caas.DeploymentMode) (watcher.NotifyWatcher, error)
Units(appName string, mode caas.DeploymentMode) ([]caas.Unit, error)
AnnotateUnit(appName string, mode caas.DeploymentMode, podName string, unit names.UnitTag) error
}
type LifeGetter ¶
LifeGetter provides an interface for getting the lifecycle state value for an application or unit.
type Logger ¶
type Logger interface {
Debugf(string, ...interface{})
Warningf(string, ...interface{})
Errorf(string, ...interface{})
Tracef(string, ...interface{})
}
Logger represents the methods used by the worker to log details.
type ManifoldConfig ¶
type ManifoldConfig struct {
APICallerName string
BrokerName string
NewClient func(base.APICaller) Client
NewWorker func(Config) (worker.Worker, error)
Logger Logger
}
ManifoldConfig defines a CAAS unit provisioner's dependencies.
func (ManifoldConfig) Validate ¶
func (config ManifoldConfig) Validate() error
Validate is called by start to check for bad configuration.
type ProvisioningInfoGetter ¶
type ProvisioningInfoGetter interface {
ProvisioningInfo(appName string) (*apicaasunitprovisioner.ProvisioningInfo, error)
WatchPodSpec(appName string) (watcher.NotifyWatcher, error)
}
ProvisioningInfoGetter provides an interface for watching and getting the pod spec and other info needed to provision an application.
type ProvisioningStatusSetter ¶
type ProvisioningStatusSetter interface {
// SetOperatorStatus sets the status for the application operator.
SetOperatorStatus(appName string, status status.Status, message string, data map[string]interface{}) error
}
ProvisioningStatusSetter provides an interface for setting status information.
type ServiceBroker ¶
type ServiceBroker interface {
Provider() caas.ContainerEnvironProvider
EnsureService(appName string, statusCallback caas.StatusCallbackFunc, params *caas.ServiceParams, numUnits int, config application.ConfigAttributes) error
DeleteService(appName string) error
UnexposeService(appName string) error
GetService(appName string, mode caas.DeploymentMode, includeClusterIP bool) (*caas.Service, error)
WatchService(appName string, mode caas.DeploymentMode) (watcher.NotifyWatcher, error)
}
type UnitUpdater ¶
type UnitUpdater interface {
UpdateUnits(arg params.UpdateApplicationUnits) (*params.UpdateApplicationUnitsInfo, error)
}
UnitUpdater provides an interface for updating Juju units from changes in the cloud.
