I am using RabbitMQ MQTT and I would like only to allow one user to publish to topics, and all other users to only subscribe. I understand that running rabbitmqctl set_permissions -p 'vhost' 'username' '.*' '.*' '.*'
will give the user permission to do anything on the vhost. How do I use the rabbitmqctl set_permissions
to allow the user to only subscribe to MQTT topics?
How can I use the "rabbitmqctl set_permissions" command to allow a RabbitMQ user to only subscribe to MQTT topics, but not publish?

The
rabbitmqctl set_permissions
structure is:So following your request, you would use the
set_permissions
command with blank regular expressions for configure and write permissions and .* for read permissions, like:UPD: Subscribing to a topic results in the MQTT plugin creating a queue and a binding, which requires configure and write permissions in that case, so you can limit access to certain queues and exchange patterns kinda like this:
allowing the user to configure and write only to the specific queues that the MQTT plugin would create and read from all queues
