Most people stick an HAproxy in front of the nodes and point clients to it.
That said, it should be fairly trivial to pick a host from a list in Bunny like
you already can do in the Java client, I'll look into adding it.

Hi Michael,
Thanks is their any patch available for this feature, or is it a good way to make connection with one node and switch to other one if we get an connection error?

Hi Michael,I have updated the bunny gem to 1.4.0(also with master branch) and then updated the RMQ settings with two hosts h1 & h2 provided with SSL certificates which is valid for h2 only, latter I tried to make the connection , but getting the below error. Ideally it should work for the second host(d1p500tlm-prxs-podrmq-a-cert.vmware.com), can you let me know what I am doing wrong here, for your reference listed the rmq settings
SETTING1:
RMQ SETTING:
production: <<: *defaults

verify_peer: true
GEMFILE: gem 'bunny', "1.4.0"

Hi Michael,
Thanks, but still I am not able to connect to the RMQ whenever I provide some invalid hosts like below, the reason for this kind of testing is my RMQ VM itself may gets down sometime in that case I want to pick the valid one.
production:
<<: *defaults rmq_settings:
port: 5671 vhost: vchs
auth_mechanism: EXTERNAL automatic_recovery: true
tls: true tls_cert: /home/logan/git/presto/ssl/server/cert.pem
tls_key: /home/logan/git/presto/ssl/server/key.pem tls_ca_certificates: ["/home/logan/git/presto/ssl/ca/ca-chain.pem"]
verify_peer: true
Bunny::TCPConnectionFailed: Could not establish TCP connection to d1p500tlm-prxs-podrmq-a-cert.vchslabs.cqom:5671:

Bunny does not recover from initial failures, however, this is trivial to
do yourself:
begin
connect
rescue Bunny::TCPConnectionFailed => _
sleep 5
retry
end
or something like that. Can you try that? This feature is certainly pretty
simplistic at the moment but I expect things to work for recovery (which
handles failed connection attempts).
