How does your Dockerfile look? It seems like it's using the .m2 in the system or something like that, and that may be read only "(Read-only file system)" which makes it impossible for lein to save the dependencies.

Can I override some setting from project.clj via command line?
Specifically, I want to run lein eftest with :eftest {:multithread? true} while project.clj contains :eftest {:multithread? false}

there's lein update-in

Perfect, thanks!

how can I build a cache for leiningen deps on a docker container?

What's worked best for me is building an "uberjar" containing all my deps outside docker, then putting that jar inside the container once it is constructed.
This leads to better start up time, and reduced RAM usage, and you can use that ubarjar to eg. start a repl or a secondary entry point by using the -cp arg to java to specify the jar as the classpath, then using clojure.main as entrypoint, pointing it to the namespace you want to run.

Why when I run lein inside a dockerfile it does not fetch the dependencies?

this was a problem of r/w permissions on dockerfile.
