Hi @Celtic67

I have checked the chef-splunk cookbook and it seems to be missing an initial value for the node[‘splunk’][‘disabled’] node object.
You can fix this by defining it in a environment json or by modifying the cookbook attribute file.

Thanks Mark, i’ve defined: the below statement in the default.rb in the recipe folder and still did not work, is that you mean on first response appreciate any help.

include_recipe ‘chef-splunk::server’
include_recipe ‘chef-splunk::client’

Are you running the code in chef-server <-> chef-client style or executing it in locally with chef-solo?
Either way you could create a small json file ./my_environment.json with the contents of

{
  "splunk": {
     "disabled": false
   }
}

and pass in a --json-attributes ./my_environment.json to the executable. This way you would have node[‘splunk’][‘disabled’] defined without touching and modifying the original code.

Thanks Mark appreciate that, this what i did: i’ve created a jason file: and placed it in the environment folder with the content below:
{
“splunk”: {
“disabled”: false
}
}
and modified the default.rb with the code below: Everything got uploaded to the chef-server however when i try to upload the sample.json i will i get the following error: ERROR: . failed to create_child: Failure creating ‘sample.json’: 400 “Bad Request” cause: {“error”:[“Invalid key splunk in request body”]} any ideas?

Thank you

require ‘json’

file = File.read(‘sample.json’)
data_hash=JSON.parse(file)
#data_hash.keys
data_hash[‘splunk’]

if node[‘splunk’][‘disabled’]
include_recipe ‘chef-splunk::disabled’
Chef::Log.debug(‘Splunk is disabled on this node.’)
return
end

if node[‘splunk’][‘is_server’]
include_recipe ‘chef-splunk::server’
else
include_recipe ‘chef-splunk::client’
endrequire ‘json’

file = File.read(‘sample.json’)
data_hash=JSON.parse(file)
#data_hash.keys
data_hash[‘splunk’]

if node[‘splunk’][‘disabled’]
include_recipe ‘chef-splunk::disabled’
Chef::Log.debug(‘Splunk is disabled on this node.’)
return
end

if node[‘splunk’][‘is_server’]
include_recipe ‘chef-splunk::server’
else
include_recipe ‘chef-splunk::client’
end

You need to define environment related keys also

{
  "name": "name_of_environment",
  "description": "description of environment",
  "json_class": "Chef::Environment",
  "chef_type": "environment",
  "default_attributes": {
    "splunk": {
      "disabled": false
    }
  }
}

Then you can run
knife environment from file path_to_your.json
