How do I use bake gc ?

It is not clear to me which arguments to pass and what they mean...

Take a look at https://github.com/ndmitchell/bake/blob/master/src/Development/Bake/Core/GC.hs#L20, which exports a function garbageCollect, and explains its arguments. Running that every 20 minutes in a loop seems reasonable. I don't call bake gc anymore, just garbageCollect directly, but looking at the command line arguments should give you a clue what bake gc does, once you know garbageCollect.

As an example, garbageCollect (20*1024*1024*1024) 0.20 (5*60*60) ["."] will make sure there is 20Gb free, there is 20% of the drive free, and it will only delete things over 5 hours old.

OK. I actually looked at it but was expecting to be able to run it as an external command so that I can schedule it in a cron for example. Given that I run server and client in a docker container, I was having trouble understanding how bake gc could work without connecting to server... There seemed to be missing a --server argument which bake client uses.

So IIRC I should put it somewhere in my server, e.g. like a thread or something and not try to use it as an external command?

[ndmitchell]

bake gc works on the client or the server - it will GC whichever disk you run it on - we currently do both server and client. Running it as a thread in your server is a good approach.

I'll leave this issue to document how to do it - the information from this ticket should be duplicated somewhere.
