As per this commit - 45e34fd#diff-b22b9fdef9829890209682dd271cccb3 - the version of the rabbitmq cookbook was downgraded to 2.4 from 3.7. The version 2.4 cookbook installs version 3.1.5 of RabbitMQ which is quite old whereas the 3.7 version installs 3.4.4 which, though not latest, is still quite recent.

Any particular reason for this downgrade?

Hello Verdigris,

First, thanks for writing this cookbook. Indeed a great help.

I"m trying to get my head across how do a node join cluster?
The cluster recipe only runs when there is a change in cookie. Also, when the node is first launch. However, since sever list is populated at run time and it's only happening at line 101, no template change is happening. It is only restarting the node and resetting it, making it fresh installation.

That explain why /etc/rabbitmq/rabbitmq.config file has cluster node list empty. However, surprisingly when i run rabbitmqctl cluster_status it shows me all the connecting nodes. I cannot figure out how did it happen. Please help me, if you could recall anything anyhow

Setup info:

env: aws
cluster: true
layer_name:

Please help me to figure out why opswork is not running the mentioned configure event properly thanks
