If you then run MinimServer with the libext directory already populated, the update will be present already and it will not be reinstalled. I am not sure if it is possible to do this when using Docker.

No the directory was empty.

I have copy&pasted the content of my running minimserver libext directory into Docker with the following content:
jminim-0.7.108.jar
minim.jar
minimlaunch$-0.7.101.jar
minimreader-0.8.100.jar
minimscript$-0.8.201.jar
minimserver-0.8-update-104.jmpkg
minimserver-0.8.252.jar
minimserver-0.8.4.7.jmpkg
minimui-0.8.222.jar
mscript.jar
mserver.jar
ohnet(linux-x64)-1.10.2315.zip
oldreader-0.8.100.jar

Same result.
