I regularly run across examples that say things like “configure this the way that you want it, run it and then use our api to do some stuff”. I generally prefer examples that are more specific for at least getting something to work quickly, preferably by doing exactly what the instructions say. As a result I decided to come up with a working example using Docker of how to use the Infinispan (aka Red Hat DataGrid) cache.
This will (at least should) build a Docker container that contains Infinispan, configures it a little, starts it and then helps you use Postman to put and get via the ReST interface.
