It contains vlmcs, a KMS test client, mainly for debugging purposes, that also can "charge" a genuine KMS server designed to run on an always-on or often-on device, e.g. router, NAS Box, ...intended to help people who lost activation of their legally-owned licenses, e.g. due to a change of hardware (motherboard, CPU, ...)
vlmcsd is not a one-click activation or crack tool intended to activate illegal copies of software (Windows, Office, Project, Visio)
Docker based in Alpine OS with vlmcsd compiled from "source" (Wind4 GitHub)
$ docker run -d -p 1688:1688 --restart=always --name vlmcsd mikolatero/vlmcsd
Now (thanks to embii74) vlmcsd process send logs to docker.
$ docker logs vlmcsd (change 'vlmcsd' with the docker's name)
