Can I bind a queue from a different vhost?

Question

I have an exchange with a vhost, user, etc from that exchange I bind different queues. The exchange and the queues are in the same vhost. Now I want to create a different vhost for a different queue but I cannot bind this new queue from the previous exchange as It is in different vhost.

What is the best solution for that? Thanks

Answer 1

Your requirement is typically done using the federation or shovel plugins. For your requirement a federated exchange seems the more appropriate.

If I quote your question by naming vhost:

The exchange and the queues are in the same vhost A. Now I want to create a different vhost B for a different queue but I cannot bind this new queue from the previous exchange as It is in different vhost.

• You create a federated exchange on vhost B
• This exchange is linked to upstream exchange on vhost A
• The new queue on vhost B is bound to this federated exchange.

Thanks, This was my first option, to create a federation. Just wondering, do we have other options? As for example in my architecture we have already more than 10 federation just for this purpose.. – Bartolomeo

No as far as I know, vhosts are isolated namespaces. By curiosity, what is your use case? – Bejarano

I have Internal rabbit with an exchange. then I have 10 federation each one for a different client and a different queue. I was wondering if It was possible to do in another way rather than all the time to federate. – Bartolomeo

What is the purpose of having a vhost per client ? (if I understand correctly) – Bejarano

so every client cannot see the queue of the others. different vhost/user for each client. Then every client has access to just one exchange and one queue – Bartolomeo

I conceive permission are not suitable for your use case. Thanks for this answer – Bejarano

so what do you think is the best solution? Thank you for all your answers and comments – Bartolomeo

I will look first at permissions, like they control access to queues, a client can have permission to access to only its queues. – Bejarano
