ConfigurationStruct swagger:model ConfigurationStruct

func (*ConfigurationStruct) EmptyWritablePtr

func (c *ConfigurationStruct) EmptyWritablePtr() interface{}

EmptyWritablePtr returns a pointer to an empty WritableInfo struct. It is used by the bootstrap to provide the appropriate structure for Config Client's WatchForChanges().

func (*ConfigurationStruct) GetBootstrap

func (c *ConfigurationStruct) GetBootstrap() bootstrapConfig.BootstrapConfiguration

GetBootstrap returns the configuration elements required by the bootstrap.

func (*ConfigurationStruct) GetInsecureSecrets

func (c *ConfigurationStruct) GetInsecureSecrets() bootstrapConfig.InsecureSecrets

GetInsecureSecrets returns the service's InsecureSecrets.

func (*ConfigurationStruct) GetLogLevel

func (c *ConfigurationStruct) GetLogLevel() string

GetLogLevel returns log level from the configuration

func (*ConfigurationStruct) GetRegistryInfo

func (c *ConfigurationStruct) GetRegistryInfo() bootstrapConfig.RegistryInfo

GetRegistryInfo returns the RegistryInfo section from the configuration

func (*ConfigurationStruct) GetTelemetryInfo

func (c *ConfigurationStruct) GetTelemetryInfo() *bootstrapConfig.TelemetryInfo

GetTelemetryInfo returns the service's Telemetry settings.

func (*ConfigurationStruct) UpdateFromRaw

func (c *ConfigurationStruct) UpdateFromRaw(rawConfig interface{}) bool

UpdateFromRaw converts configuration received from the registry to a service-specific configuration struct which is then used to overwrite the service's existing configuration struct.

func (*ConfigurationStruct) UpdateWritableFromRaw

func (c *ConfigurationStruct) UpdateWritableFromRaw(rawWritable interface{}) bool

UpdateWritableFromRaw updates the Writeable section of configuration from raw update received from Configuration Provider.

type Credentials

type Credentials struct {
	Username string
	Password string
}

Credentials encapsulates username-password attributes.

type ExternalMqttConfig

type ExternalMqttConfig struct {
	// Url contains the fully qualified URL to connect to the MQTT broker
	Url string
	// SubscribeTopics is a comma separated list of topics in which to subscribe
	SubscribeTopics string
	// PublishTopic is the topic to publish pipeline output (if any)
	PublishTopic string
	// ClientId to connect to the broker with.
	ClientId string
	// ConnectTimeout is a time duration indicating how long to wait timing out on the broker connection
	ConnectTimeout string
	// AutoReconnect indicated whether or not to retry connection if disconnected
	AutoReconnect bool
	// KeepAlive is seconds between client ping when no active data flowing to avoid client being disconnected
	KeepAlive int64
	// QoS for MQTT Connection
	QoS byte
	// Retain setting for MQTT Connection
	Retain bool
	// SkipCertVerify indicates if the certificate verification should be skipped
	SkipCertVerify bool
	// SecretPath is the name of the path in secret provider to retrieve your secrets
	SecretPath string
	// AuthMode indicates what to use when connecting to the broker. Options are "none", "cacert" , "usernamepassword", "clientcert".
	// If a CA Cert exists in the SecretPath then it will be used for all modes except "none".
	AuthMode string
	// RetryDuration indicates how long (in seconds) to wait timing out on the MQTT client creation
	RetryDuration int
	// RetryInterval indicates the time (in seconds) that will be waited between attempts to create MQTT client
	RetryInterval int
}

ExternalMqttConfig contains the MQTT broker configuration for MQTT Trigger

type HttpConfig

type HttpConfig struct {
	// Protocol is the for the HTTP Server to use HTTP or HTTPS
	// If HTTPS then the Secret store must contain the HTTPS cert and key
	Protocol string
	// SecretName is the name in the secret store for the HTTPS cert and key
	SecretName string
	// HTTPSCertName is name of the HTTPS cert in the secret store
	HTTPSCertName string
	// HTTPSKeyName is name of the HTTPS key in the secret store
	HTTPSKeyName string
}

HttpConfig contains the addition configuration for HTTP Server

type PipelineFunction

type PipelineFunction struct {
	// Parameters is the collection of configurable parameters specific to the built-in configurable function specified by the map key.
	Parameters map[string]string
}

PipelineFunction is a collection of built-in pipeline functions configurations. The map key must be unique start with the name of one of the built-in configurable functions

type PipelineInfo

type PipelineInfo struct {
	// ExecutionOrder is a list of functions, in execution order, for the default configurable pipeline
	ExecutionOrder string
	// PerTopicPipelines is a collection of pipelines that only execute if the incoming topic matched the pipelines configured topic
	PerTopicPipelines map[string]TopicPipeline
	// TargetType indicates if raw, []byte type, or metric, Dtos.Metric, is to be used for the TargetType
	TargetType string
	// Functions is a collection of pipeline functions with configured parameters to be used in the ExecutionOrder of one
	// of the configured pipelines (default or pre topic)

	// Topics is the set of comma separated topics matched against the incoming to determine if pipeline should execute
	Topics string
	// ExecutionOrder is a list of functions, in execution order, for the pipeline instance
	ExecutionOrder string
}
