Application Layer

GremlinService

ALFI is currently in an open beta.

To create a com.gremlin.GremlinService, you need a com.gremlin.GremlinCoordinatesProvider, which needs a com.gremlin.ApplicationCoordinates.

To construct a GremlinService using the alfi-aws library:

java

1final GremlinServiceFactory factory = new GremlinServiceFactory(new GremlinCoordinatesProvider() {
2            @Override
3            public ApplicationCoordinates initializeApplicationCoordinates() {
4                ApplicationCoordinates coords = AwsApplicationCoordinatesResolver.inferFromEnvironment()
5                        .orElseThrow(IllegalStateException::new);
6                return coords;
7            }
8        });
9final GremlinService gremlinService = factory.getGremlinService();

Design

com.gremlin.GremlinService should be a singleton.

Injecting fault

Once you have a reference to the com.gremlin.GremlinService singleton and have defined your Custom com.gremlin.TrafficCoordinates, you can inject fault like this:

java

1gremlinService.applyImpact(trafficCoordinates);
