Error using source in Puppet manifest

Question

I am trying to change a file in puppet agents and I have written the below code.

modules/
├── helloworld
│   └── manifests
│       ├── init.pp
│       └── motd.pp
└── ssh
    ├── manifests
    |    └── init.pp
    └── ssh_config

my Puppet manifest code:

# modules/ssh/manifests/init.pp 
class ssh {
  package { 'openssl':
    ensure => present,
    before => File['/etc/ssh/sshd_config'],
  }

  file {'ssh_config':
    ensure => file,
    path   => '/etc/ssh/sshd_config',
    mode   => "600",
    source => "puppet:///modules/ssh/ssh_config",
  }

  service {'sshd':
    ensure    => running, 
    enable    => true,
    subscribe => File['/etc/ssh/sshd_config'],
  }
}

Below is the main manifest's code:

# manifests/site.pp 
node default {
  class { 'ssh': }
}

Below is the error I am receiving:

Info: Using configured environment 'production'

Answer 1

Your ssh_config file location needs to be in the files directory of your module to be used with the Puppet URI in the source attribute like you are doing.

modules/
├── helloworld
│   └── manifests
│       ├── init.pp
│       └── motd.pp
└── ssh
    ├── manifests
    |    └── init.pp
    └── files
         ├── ssh_config

Also, you probably meant your package resource to be openssh and not openssl .
