Hello ,
In this custom function i am trying to download a file and then parse it ,
that works correctly , now i want the url value to be in a variable or
hiera and this custom function fetches that value from variable.
Using lookupvar doesn't works . Below is the code and error.
require_relative 'inifile'
require 'open-uri'
Puppet::Parser::Functions.newfunction(
:inireadvalue, :type => :rvalue,
:arity => 4,
:doc => "Reads an .ini file and...") do |args|
package = args[0]
filename = args[1]
section = args[2]
key = args[3]
remote_base_url = lookupvar('$::windows_l2_agent::l2_agent_list::url')
remote_page_name = "#{package}" + "/" + "#{filename}"
remote_full_url = remote_base_url + "/" + remote_page_name
remote_data = open(remote_full_url).read
my_local_file = open("/tmp/#{filename}", "w")
my_local_file.write(remote_data)
my_local_file.close
if !File.exist?("/tmp/#{filename}")
raise(Puppet::ParseError, 'inireadvalue(): Path and file provided does not
exists ' +
'Provide the correct path')
end
fileload = IniFile.load("/tmp/#{filename}")
data = fileload[section]
value = data[key]
return value
end
*Error it gives is *
