Martini Service Registry Functions
The Registry component in Martini plays a pivotal role in managing and accessing various functions and services. This section covers the usage of Registry functions in Martini.
Accessing Service Registry Functions
Martini's interface provides a straightforward method to access service registry functions:
- Navigate to the functions node in the Martini navigator.
- Locate the folder named “service registry”, which contains a list of functions for interacting with the service registry.
Usage of Service Registry Functions
Functions within the "service registry" folder can be easily integrated into your service. These functions can be included by either drag-and-drop methodology or through content assist (initiated by pressing the full stop key and typing "service registry").
Example: Utilizing the "Get Service Instance" Function
The "Get Service Instance" function is a prime example of a service registry function. It requires a parameter called service name
and interacts with Martini's cluster manager to fetch service instances.
- When invoking this function, specify the service name, such as the fully qualified name of a running API.
- The function returns a "service instance" data model containing details about the registered service.
- This data model can be further mapped and utilized for subsequent operations, like logging or processing.
Logging the Service Instance
As a practical application, consider adding a logger function to your service that outputs the "service instance" data model as a JSON string. This JSON output typically includes vital information such as the URI and the host where the service can be accessed.
