From a quick look at the features, Pega could theoretically work.  It does not look like it has been done before, though, and of course isn't officially supported, but it does look like it supports the software stack Pega needs.

However, if you're looking to package up Pega like Springboot does, it will be easier to use the official Docker images.  See the PDN for more details: https://pdn.pega.com/pega-platform-docker-support/pega-platform-docker-support .  This is official, although quite new, but may let you do what you want with less work.
