Sensu data bag file

Anthony_Kong · November 4, 2014, 12:18am

Hi

I am trying to use sensu with chef-solo. Chef requires a data_bag file. Unfortunately I can’t locate any info about what need to go into a data_bag file for the sensu package. I wonder if anyone can give me a pointer?

Currently I have put a file ‘mycompany.json’ in ~/.chef/data_bags/sensu/

The content of mycompany.json is just:

{
"id”:“mycompany”
}

This is the error message I am getting:

==> default: TypeError
==> default: ---------
==> default: can’t convert Array into String
==> default:

Can you copy the chef-stacktrace.out file? Looks like you’re passing an unexpected data type somewhere, but it’s not checked until it blows up somewhere in chef’s internals.

This looks like it’s from a different chef-client run, it’s indicating a failure to read the private key it needs to establish its identity with the Chef Server.

BTW I have found out how to generate the data bag data file: https://github.com/sensu/sensu-chef/tree/master/examples/ssl
But it looks like you got it sorted out. I’ll dig a little deeper and see if I can find where we can improve the error messages.

Cheers, Tony

Don't data bag item accesses assume you're in client-server mode and
thereby trigger the authentication code?

Tony, I'd suggest using chef-client in local mode rather than Solo if
you have data bags.

Hi Julian,

I am using chef-solo from vagrant. I probably should provide this context
at the beginning.

So in theory I shouldn't need to provide the data bag if I am just using
chef-solo. Is it right?

Cheers, Tony

It depends how the author wrote the cookbook you're trying to use.
Based on your description, it sounds like they assume you are using
Chef Client (or at least Chef Client in local mode), and if so, you'll
need to provide a data bag.

See solo.rb for how to set the
data_bag path for chef-solo, and also see the README.md in the sensu-chef
cookbook, where it says:

TESTING

This cookbook comes with a Gemfile, Cheffile, and a Vagrantfile for testing
and evaluating Sensu.

cd examples
gem install bundler
bundle install
librarian-chef install
vagrant up
vagrant ssh

Hope that helps,

Peter
