Official docker configuration example is broken (Undefined constant "CodeIgniter\Log\CI_DEBUG")

The docker example given in the official documentation results in a non-working production environment. I’ve read on Discord that it seems to be the case since Castopod 1.6.1 (because of some codeigniter update maybe).

The error thrown is the following:

The problem seem to be that redis needs a password. Everything works after setting one.

So docker-compose.yml in the documentation should be updated with something like this:
