Keeping default user and password secret

[kennylajara]

I created a file rabbimq.conf and this is the current content:

loopback_users.guest = false
listeners.tcp.default = 5672
disk_free_limit.relative = 2.0
default_pass = test
default_user = test

I don't want to gitignore the this file, but I don't want my credentials to be stored. Ia m trying to use some king of environment variable or something but you deprecated the default username and password environment variables on the last version.
How can I keep secret my credentials now?

RabbitMQ 3.9.4 added support for a few variables directly (instead of the overly complex bash script): https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.9.4 and are allowed though the entrypoint script with #519.

(Note that environment variables are not secret from someone on the host or with access to Docker)
