This series how to set up a WebSphere Liberty Profile cluster with standard Docker swarm/stack and presently released official images.
The purpose of this is to set up a simple working cluster to allow developers to ensure that their work will function correctly in a clustered environment and neither a robust system with failovers nor scaling.

There may be times that you’d need to clean up resources such as temporary files or in my case deregister a container from a WebSphere Liberty Collective. To set this up, we just need to use `trap` on `bash` to handle any cleanup. This will also work with `docker-compose.yml` built stacks and `replica`s.

Actually this is more automatic integration testing since the components are tied together. I used Weld for my CDI, EclipseLink for my JPA and Hibernate Validator for my Bean Validation implementations and H2 for my in-memory test database.
There are many algorithms that generate and validate Canadian SIN numbers. This is the one I use with bean validation. Unlike most other implementations I took into consideration that `8` is not used as the first character in a Canadian SIN. In addition, I utilized a map to deal with the doubled number for the even digits rather than doing the calculation and dealing with greater than 10 results. No regexes are involved either.
