I haven't done a lot of docker, but I think I have everything set up right... except that I have crashing judgehosts when they try to compile a java program. Is there anything special I need to do when initializing the docker container?Thanks,

If you only need a judgehost you can use the latter.NickyOn 22 Jan 2019, at 12:47, Matthew Fahrenbacher <matfah@d219.org> wrote:Hi all. So I'm almost done with my next contest, but I see that the Live Images haven't been updated in about a year, so the version of the judgehost on the Live Image won't match with the latest release of the domjudge server. (I tried the most recent Live Image, and it didn't want to boot, even though older ones would)._______________________________________________I'm about to go through the process of building one myself following the directions here, but I wanted to check first to see if a prebuilt one was going to be created in the near future to save me the hassle.Thanks!Matt FahrenbacherNiles West High School
