Docker RabbitMQ in detached mode logging

Question

I am running RabbitMQ in the docker container in detached mode. I am doing this so I can set some values using rabbitmqctl.

I added tail -f /dev/null so the container doesn't shutdown

However when I do this, I get no logging from the docker container.

How can I run rabbitmq-server -detached AND get logging to the "console"?

Answer 1

docker logs -f [container name or container ID] 

will give you the container log. If rabbitmq logs to an specific file you can then do:

docker exec [container name or container ID] tail -f [PATH to the rabbot mb log file]

To get the container ID or name in case that you don't know it use:

docker ps

Answer 2

One alternative is to set RABBITMQ_LOG_BASE to a shared volume directory.

In your dockerfile, add:

ENV RABBITMQ_LOG_BASE="/var/log/foo"

Then, run the container with:

docker run -d -v /var/log/bar:/var/log/foo your_image

Then you can get the data directly in your host in the directory /var/log/bar.
