I'm willing to work on this myself but my knowledge is limited when it comes to docker. So I need a pointer to why this does not work at the moment. In my naive view, it should just replace the binary and restart the service.
The change does not have to be permanent, it does not have to survive container restarts.
Edited/fixed the command in the first message. Can I make this change permanent? I was thinking about getting a docker image for playing around with and I want a special FTL branch, say new/superclients.
Can I run a command and commit a "new" container where the FTL was replaced?
Sorry if this sounds ignorant or naive, I find it still a bit hard to use the right vocabulary with docker and its ecosystem.
