Hello,
Could someone please take a look at the two open pull requests on the port-allocator-plugin and hopefully merge them.
Change by KostyaSha: Don't enforce upper case for variables
If you have software that expects lower case variable, then you are unable to use this plugin at all.
Change by sboschman: Support for a global pool of port numbers
Make it possible to generate unique port numbers for the entire Jenkins cluster instead of unique port numbers per node.
Use case: jobs running on different Jenkins nodes can start an
application container (Docker) for integration testing on the same remote host.
Thanks in advance.
