## Traffic Generation

2 copies of the traffic gen containers are currently running on cloud run until I move them over to the GKE cluster.
The health check doubles as the target REST endpoint for now.
Note: HTTPS termination is on the cloud run gateway - if we don't terminate on the API Gateway and/or the LB fronting the GKE cluster then I'll add a self signed to the app - for now we use the Google cert for https.

CICD
Currently there is a CSR trigger on cloud build to run the maven build and build/push the container into artifact registry.  The cloud run builds are static but can be switched to trigger.  I expect we can add a trigger on the cloud deploy job once I have moved the container to GKE.

To view - open swagger or use direct curls or the browser
https://traffic-generation-source-vyua7q27tq-nn.a.run.app/nbi/swagger-ui.html#/forwarding-controller/getTrafficUsingGET
enter for example 120k 1ms traffic https://traffic-generation-source-vyua7q27tq-nn.a.run.app/nbi/forward/traffic?delay=1&dns=traffic-generation-target-vyua7q27tq-pd.a.run.app&iterations=120000&to=80 

view the metrics on both source and target.  These requests have no real load on the backend (db marshall/unmarshall as part of orm) therefore 1k requests/sec only scales a smaller than normal 1g/1vCore container up to 3 instances.  Once we get backend load scaling should occur with over 1k req/sec traffic
