chef error ERROR: No such file or directory @ rb_sysopen when a run list is executed

[Babu George]

Hi All,
I have 2 recipes of which the first recipe creates a file and the second recipe reads the contents of this file and add in another file using a template.

When I gave a direct file read command in my second recipe, I got the error "ERROR: No such file or directory @ rb_sysopen when a run list is executed". So I have used a ruby_block with not_if guard and the compilation error is avoided. But now I am unable to read the value which is read from the file inside the ruby_block outside. hence my output file has no values for this field.

The command and recipe details are like this.

recipe 1 => creates a file

recipe 2 => reads the contents of the file created by recipe 1 and saves into another file which is created using a template

runlist is recipe1,recipe2

I tried using a global variable inside the ruby block, but that also not returning any value.

Following is the code snippet

#Read the ssh_public key to add as a field in json

$communicator = nil       # Global Variable

def readKey()
    ruby_block 'ssh_publicKeyText' do
         block do
            $communicator =  File.read("/u01/app/paas/keys/ssh_public.pub")
         end
     only_if { File.exist?('/u01/app/paas/keys/ssh_public.pub') }        # guard to avoid compile error when the file does not exists
     end
return $communicator
end

vmPublicKeyText = readKey()      # function call

template "/u01/app/paas/json/fcubs-dbcs-create.json" do
  source "dbaas_schema.erb"

  group 'root'
