def
getMountedPath(volumeMount: VolumeMount): Path
The path mounted for a VolumeMount request from a streamlet.
The path mounted for a VolumeMount request from a streamlet. In a clustered deployment, the mounted path will correspond to the requested mount path in the VolumeMount definition. In a local environment, this path will be replaced by a local folder.
- volumeMount
the volumeMount declaration for which we want to obtain the mounted path.
- returns
the path where the volume is mounted.
- Exceptions thrown
MountedPathUnavailableException
in the case the path is not available.

runtimeBootstrapServers(topic: Topic): String
The runtime 'bootstrap.servers' for the given topic.
The runtime 'bootstrap.servers' for the given topic. This is provided by the cloudflow-operator when creating the streamlet's 'cloudflow.runner' configuration. A 'bootstrap.servers' will always be provided as long as a 'default' Kafka cluster is defined during the install of the cloudflow-operator.

def
streamletConfig: Config
The subset of configuration specific to a single named instance of a streamlet.
The subset of configuration specific to a single named instance of a streamlet.
A Streamlet can specify the set of environment- and instance-specific configuration keys it will use during runtime through configParameters. Those keys will then be made available through this configuration.
An empty configuration will be returned if the streamlet doesn't contain any configuration parameters.

def
streamletRef: String
The streamlet reference which identifies the streamlet in the blueprint.
The streamlet reference which identifies the streamlet in the blueprint. It is used in a Streamlet for logging and metrics, referring back to the streamlet instance using a name recognizable by the user.
