Types ¶
type Backend ¶
type Backend interface {
// ModelUsesCredential determines if the model uses given cloud credential.
ModelUsesCredential(tag names.CloudCredentialTag) (bool, error)
// ModelCredential retrieves the cloud credential that a model uses.
ModelCredential() (*ModelCredential, error)
// WatchCredential returns a watcher that is keeping an eye on all changes to
// a given cloud credential.
WatchCredential(names.CloudCredentialTag) state.NotifyWatcher
// InvalidateModelCredential marks the cloud credential that a current model
// uses as invalid.
InvalidateModelCredential(reason string) error
// WatchModelCredential returns a watcher that is keeping an eye on what cloud credential a model uses.
WatchModelCredential() (state.NotifyWatcher, error)
}
Backend defines behavior that credential validator needs.
func NewBackend ¶
func NewBackend(st StateAccessor) Backend
type CredentialValidatorAPI ¶
type CredentialValidatorAPI struct {
*credentialcommon.CredentialManagerAPI
// contains filtered or unexported fields
}
func NewCredentialValidatorAPI ¶
func NewCredentialValidatorAPI(ctx facade.Context) (*CredentialValidatorAPI, error)
NewCredentialValidatorAPI creates a new CredentialValidator API endpoint on server-side.
func (*CredentialValidatorAPI) ModelCredential ¶
func (api *CredentialValidatorAPI) ModelCredential() (params.ModelCredential, error)
ModelCredential returns cloud credential information for a model.
func (*CredentialValidatorAPI) WatchCredential ¶
func (api *CredentialValidatorAPI) WatchCredential(tag params.Entity) (params.NotifyWatchResult, error)
WatchCredential returns a NotifyWatcher that observes changes to a given cloud credential.
func (*CredentialValidatorAPI) WatchModelCredential ¶
func (api *CredentialValidatorAPI) WatchModelCredential() (params.NotifyWatchResult, error)
WatchModelCredential returns a NotifyWatcher that watches what cloud credential a model uses.
type CredentialValidatorAPIV1 ¶
type CredentialValidatorAPIV1 struct {
*CredentialValidatorAPI
}
func NewCredentialValidatorAPIv1 ¶
func NewCredentialValidatorAPIv1(ctx facade.Context) (*CredentialValidatorAPIV1, error)
NewCredentialValidatorAPIv1 creates a new CredentialValidator API endpoint on server-side.
func (*CredentialValidatorAPIV1) WatchModelCredential ¶
func (*CredentialValidatorAPIV1) WatchModelCredential(_, _ struct{})
Mask out new methods from the old API versions. The API reflection code in rpc/rpcreflect/type.go:newMethod skips 2-argument methods, so this removes the method as far as the RPC machinery is concerned.
WatchModelCredential did not exist prior to v2.
type CredentialValidatorV1 ¶
type CredentialValidatorV1 interface {
InvalidateModelCredential(params.InvalidateCredentialArg) (params.ErrorResult, error)
ModelCredential() (params.ModelCredential, error)
WatchCredential(params.Entity) (params.NotifyWatchResult, error)
}
CredentialValidatorV1 defines the methods on version 1 facade for the credentialvalidator API endpoint.
type CredentialValidatorV2 ¶
type CredentialValidatorV2 interface {
InvalidateModelCredential(params.InvalidateCredentialArg) (params.ErrorResult, error)
ModelCredential() (params.ModelCredential, error)
WatchCredential(params.Entity) (params.NotifyWatchResult, error)
WatchModelCredential() (params.NotifyWatchResult, error)
}
CredentialValidatorV2 defines the methods on version 2 facade for the credentialvalidator API endpoint.
type ModelAccessor ¶
type ModelAccessor interface {
CloudCredential() (names.CloudCredentialTag, bool)
ModelTag() names.ModelTag
Cloud() string
WatchModelCredential() state.NotifyWatcher
}
ModelAccessor exposes Model methods needed by credential validator.
type ModelCredential ¶
type ModelCredential struct {
// Model is a model tag.
Model names.ModelTag
// Exists indicates whether the model has a cloud credential.
// On some clouds, that only require "empty" auth, cloud credential
// is not needed for the models to function properly.
Exists bool
// Credential is a cloud credential tag.
Credential names.CloudCredentialTag
// Valid indicates that this model's cloud authentication is valid.
//
// If this model has a cloud credential setup,
// then this property indicates that this credential itself is valid.
//
// If this model has no cloud credential, then this property indicates
// whether or not it is valid for this model to have no credential.
// There are some clouds that do not require auth and, hence,
// models on these clouds do not require credentials.
//
// If a model is on the cloud that does require credential and
// the model's credential is not set, this property will be set to 'false'.
Valid bool
}
ModelCredential stores model's cloud credential information.
type StateAccessor ¶
type StateAccessor interface {
Model() (ModelAccessor, error)
CloudCredential(tag names.CloudCredentialTag) (state.Credential, error)
WatchCredential(names.CloudCredentialTag) state.NotifyWatcher
InvalidateModelCredential(reason string) error
Cloud(name string) (cloud.Cloud, error)
}
StateAccessor exposes State methods needed by credential validator.
func NewStateShim ¶
func NewStateShim(st *state.State) StateAccessor
NewStateShim creates new state shim to be used by credential validator Facade.
