Puppet: mount a SAMBA share at boot

First, create a credentials file in your acme module:
acme\files\samba\myshare.smb.credentials
and inside put:

username=myuser
password=mypassword

I was unable to make it mount an unprotected share..... so just have it protected by username/password.

Then in your acme init.pp read a boolean

$acme_install_sambamyshare = any2bool(hiera('acme_install_sambamyshare', false)),

Create a samba.pp class (file):

# == Class: acme::samba
#
# Manages samba mounts
#
class acme::samba {
  if $acme::acme_install_sambamyshare {
    file { '/data/myshare/':
      ensure => directory,
      owner  => "soa",
      group  => 'soa',
      mode   => '0775',
    }

    file { '/etc/myshare.smb.credentials': source => 'puppet:///modules/acme/samba/myshare.smb.credentials', 
  owner => root,
      mode => '0700', } ->
    mount { 'myshare':
      name    => '/data/myshare/',
      atboot  => 'true',
      device  => '//windowshost/sharedfolder',
      ensure  => 'mounted',
      fstype  => 'cifs',
      options => "credentials=/etc/myshare.smb.credentials,rw,nounix,iocharset=utf8,file_mode=0777,dir_mode=0777",
      require => [Package['samba-client'], Package['cifs-utils'], File['/data/myshare/'], File['/etc/myshare.smb.credentials']],
    }
  }

}

Don't forget to declare the samba class in your init.pp!

If you do cat /etc/fstab you should see something like this:

//windowshost/sharedfolder /data/myshare/ cifs credentials=/etc/myshare.smb.credentials,rw,nounix,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0

If you want to do the same thing manually, this is the recipe:

yum install smbclient
//yum install cifs-utils for Ubuntu
/bin/mount -t cifs -o username=someuser,password=somepassword,rw,nounix,iocharset=utf8,file_mode=0777,dir_mode=0777 //windowshost/sharedfolder /data/myshare/

To remove a mountpoint, use umount:

umount /data/myshare/

it supports also a -f (force) option:

umount -f /data/myshare/
