从 AWS Opsworks Stacks Chef 11 迁移到 Chef 12 - 堆栈属性问题

Question

2 questions. I'm striking out on the AWS docs and forum threads here...

When you migrate to opsworks stacks chef12 attributes is no longer available from the node object

"Stack settings are no longer available as Chef attributes, so stack settings can no longer be accessed through the Chef node object. For more information, see the AWS OpsWorks Stacks Data Bag Reference." as per the official docs.

The problem is. How can i get at those top level attributes stored in the layers-general settings-custom json? I know these get passed to the instance b/ci can find that json in /var/chef/runs/{randomstring}/attrib.json BUT that is a level above the databags directory. i can't see anyway to access that as a variable in opsworks/chef.

Second question, is there any way to access that random chef run directory as a variable in opsworks/chef? if so I can go grab that data easily.

I have seen this: Get Custom JSON from Stack Settings in AWS OpsWorks with Chef 12 but based on my experimenting I can't seem to access those #{node... values in chef12 opsworks stacks.

@coderanger you are probably my only hope here.

ps. is it just me or is opsworks TERRIBLE. that is all.

Answer 1

OK. after continuing to dig - apparently despite what the official Docs say in one place - you CAN still access that top level custom JSON with the original syntax #{node['whateveryourkeyis']}...etc. The errors I was getting when trying that turned out to be unrelated so, there you go, fwiw you can sill grab that custom json but not the other attributes of applications - those have moved on to the databags.

oh, and to answer the other question - yes i'm still pretty sure opsworks IS terrible. change my mind.
