Error AWS AutoScale and rabbitmq

Liam_Kirsher · August 8, 2014, 5:38pm

Hope someone can help with this!
Converge fails when using AWS AutoScaling, but succeeds when doing a
normal EC2 server create.
The source of the error is in the rabbitmq cookbook. Somehow the hash
that is expected for kernel (I believe this is Erlang kernel?) becomes
an array.

Starting with "knife ec2 server create" the instance comes up fine.
Adding the same run_list to auto scale config, the converge fails. I
tried adding this to the node

override[:rabbitmq][:kernel] = {}

But that had no effect.
I did find someone else having a very similar issue installing with
Vagrant, but there was no response.

Sounds like that’s being overridden that in node attributes somehow. The default attributes[0] for that cookbook set a few attributes under kernel:

Erlang kernel application options

See Erlang -- kernel

default['rabbitmq']['kernel']['inet_dist_listen_min'] = nil

default['rabbitmq']['kernel']['inet_dist_listen_max'] = nil

Tell Erlang what IP to bind to

default['rabbitmq']['kernel']['inet_dist_use_interface'] = nil

I would assume you’re setting that interface at least as the cookbook doesn’t attempt to determine that automatically as far as I can tell. Can you open chef-shell once it fails once being bootstrapped by AWS and see what node.rabbitmq.kernel actually is?

Yeah. I've searched for references to rabbitmq and kernel, and found
nothing. Not setting any of these in my recipe.

I think the kernel parameters must be optional.
Can you open chef-shell once it fails once being bootstrapped by AWS
and see what node.rabbitmq.kernel actually is?
I'm attempting to do this, but not familiar with chef-shell so that may
be why it's not working. Can you offer a little more info on how to
start chef-shell and what commands to use in it?

chef-shell -c client.rb -j first-boot.json

Fixed it. It turned out I had gotten two versions of ruby on there, and
that was messing things up. Exactly how I'm not sure, but it's
working now.

My boot script now has --
apt-get update
apt-get upgrade
apt-get install -y ruby1.9.1-dev ruby1.9.1 rubygems s3cmd
gem1.9.1 install ohai chef --no-rdoc --no-ri --verbose
mkdir -p /etc/chef
cd /etc/chef
