Connection refused - connect 2 for localhost port 25 chef devops

Question

I am working on chef where I have a helper library with the following code

require 'net/smtp'
 module HandlerSendEmail
class Helper
def send_email_on_run_failure(node_name)
  message = "From: Chef <chef@chef.io>\n"
  message << "To: Grant <xyz@test.com>\n"
  message << "Subject: Chef run failed\n"
  message << "Date: #{Time.now.rfc2822}\n\n"
  message << "Chef run failed on #{node_name}\n"
  Net::SMTP.start('localhost', 25) do |smtp|
    smtp.send_message message, 'chef@chef.io', 'xyz@test.com'
  end
end

But when I run the recipe I get

Chef Client failed. 0 resources updated in 02 seconds
[2017-10-30T05:19:38+00:00] ERROR: Connection refused - connect(2) for "localhost" port 25
[2017-10-30T05:19:38+00:00] ERROR: Connection refused - connect(2) for "localhost" port 25

what do I do?

Answer 1

With the information that you’ve provided it looks like you don’t have an actual SMTP server on your localhost. You would need an actual SMTP server connection on the localhost.
