Since this is your first code change to the company app, and because this app takes a microservices approach, you will need to understand how it gets deployed and also how all of the services are interconnected. To obtain a quick and insightful overview, you will use Weave Cloud to visualize microservice communication, as well as cloud deployment.
To begin, sign up for Weave Cloud .
Once signed up, create a new instance and call it Katacoda. Weave Cloud assigns the new instance a Service Token, which is found on right-hand side of the screen in the Probes panel.
Make a note of the Service Token. It will be used later on in this tutorial to launch the Weave Scope probes onto your hosts within your cluster, so that metrics about the Sock Shop app can be sent and visualized in Weave Cloud.
The Service Token can always be accessed by clicking on the Settings icon from the main header in Weave Cloud.
