Kubernetes Coupling Graph

This is a basic kubernetes coupling graph visualizer to evaluate the growth and coupling of microsservice architecture built applications

Requirements

Need to create link for libpcap.so.1 even if libpcap-dev is installed libpcap.so.1

Build

export GO111MODULE=on
go build -o ./app -ldflags "-s -w" .

Run in Dev Environment

Teastore

To setup the Teastore microsservice architecture dev environment like Teastore, you will need to use a orchestration environment like Kubernetes.

First, you need to turn on the Asynchronous Message System (RabbitMQ) for the Teastore:

kubectl create -f https://raw.githubusercontent.com/DescartesResearch/TeaStore/master/examples/kubernetes/teastore-rabbitmq.yaml

This will be a central logging service that all services will comunicate with.

You need to wait 2 to 5 minutes for the service to become online and running. Then start the instrumented version of the Teastore:

kubectl create -f https://raw.githubusercontent.com/DescartesResearch/TeaStore/master/examples/kubernetes/teastore-ribbon-kieker.yaml

The main services will be available via localhost on ports 30080 (webui) and 30081(logs)

If you are done and want to remove everything, just do:

kubectl delete pods,deployments,services -l app=teastore

Running the Coupling Graph Creator Application:

With the compiled version of the app on the same machine as the cluster is running, do:

./app

And follow the instructions. Basically you need to use the app and all it's functionalities for some time and then report back to the command line to get the output.
