Cookbook not compatible with default opsworks chef 12

[cratz]

Expected Behavior

Cookbook is compatible with chef 12 (used by OpsWorks)

Actual Behavior

deploy_resource cookbook requires chef >= 13.0
Using chef-version will not help since it already fails on checking metadata.rb

Custom JSON

{
  "chef-version": 16
}

Chef log including error

ERROR: Cookbook 'deploy_resource' version '1.0.3' depends on chef version [">= 13.0"], but the running chef version is 12.18.31

I ran into the same problem a week ago, suddenly starting new instances does not work anymore. Until now I did not find a way to mitigate this problem or workaround it.
ANY HELP or ideas would be so great - it kills the whole deployment and break setup of our rails-instances.

UPDATE: Downgrading to v1.15.0 did fix the problem for now - but not really the optimal solution

I created a new branch which should do the trick: fix/include-deploy-resource. Can you please take a look if it works for you? I tested it both with Chef 12 and 14 and looks like it's working.

I tested it and it fixes the problem, yes. Thanks a lot @ajgon for your quick response.
( I talked to @cratz - he did move away from opsworks in the project he was having this problem. )

@ajgon Thanks a lot for the fix. Maybe I will give it a try later again.
