Where do we find the dockerfiles for images used in the CI? #563

After learning more about docker containers I guess those mostly are based on common distro containers and add the necessary tools on top. Are the dockerfiles for the images posted to ghrc.io public?
Side note: the public images can be accessed without a token also from the outside, for example to base own containers on them for gitpod; but after tinkering with that and seen how much work it is to add gitpod functions on these I think about doing it the other way around (copying the definitions from KDAB's dockerfiles to extend the one gitpod provides).

... and: would you consider to add some things to the KDAB docker files like perf (which then allows to work with the record files we have in the repo)?

This isn't cleaned up yet, but a working perf can be integrated with
