Providing rabbitmq.conf in a docker-compose file gives “sed: cannot rename /etc/rabbitmq/sedMaHqMa: Device or resource busy”

Question

My docker-compose looks like this:

version: \'3.2\'
services:
  mq:
    hostname: ${HOST_NAME}
    ports:
      - \"5671:5671\"
      - \"5672:5672\"
      - \"1

This seem to be an issue with current rabbitmq Dockerfile. Particulary sed command seem not work properly on configfile mapped as volume. However as you have control over your rabbitmq.conf anyway, why not include default user and password to this file

default_user = admin
default_pass = YourStrongPasswort

and remove RABBITMQ_DEFAULT_USER and RABBITMQ_DEFAULT_PASS out of your compose file. This is fastest work-around probably. Just tested, works for me (official rabbitmq:3.7-management).
