WildFly mini-serie

[tommaso-borgato]

Create a mini-serie to fill the gap we ave at the beginning of our cloud journey with WildFly: the goal is to help users to experiment with WildFly based containerized microservices on Kubernetes;
It should be kept as basic as possible and cover:

1. creating a Docker image containing a WildFly based microservice
2. running this Docker image on Kubernetes

This basic example should then be extended with some common patterns:

1. interacting with a DB
2. interacting with an external JMS Broker
3. interacting with an external Cache

The initial version should at least cover these topic, and can be further extend later with some more patterns;
