Default User and Password from Environment

[abdullahenesoncu-s4e]

When I am trying to automatize process for creating a lavinmq instance using docker, I need to set password and username from docker compose file as environment variable. Is there any way to do it inside lavinmq?

For rabbitmq, we can set it like below:
RABBITMQ_DEFAULT_USER = 'xxx'
RABBITMQ_DEFAULT_PASS = 'yyy'

If it is not a case for lavinmq, how can I automatize the process for creating lavinmq docker with a specific username or password?
