Description

This fsutil module provides a higher level interface to common filesystem actions. It aims to reduce the code in your profiles. Most of the action can be driven through Hiera. Some assumptions are made:

• only performs the mount action (and inserts entry into fstab)
• manages the mount point directory

Instructions

Call the class from your code, e.g.

class { 'fsutil': }

or

include 'fsutil'

Use Hiera to drive the configuration. E.g.:

fsutil::nfs_mounts:
  /code: mac:/Users/matt/code
  /downloads: 
    device: mac:/Users/matt/Downloads
    options: ro,hard,intr

Data Structures

nfs_mounts

To mount a number of NFS mounts, define a Hash in Hiera with all the mount points as the keys. The Hash values can either be a String of the remote share to mount or another Hash with the following additional options:

• device - remote share to mount
• options (default = 'defaults') - the mount options to use,
• mode (default = 0755) - the mode of the mount point
• umask (default = 0022) - the umask to use when any parent directories get created Any parent directories needed for the mount point (and the mount point itself) will be created and managed by Puppet

Defined Resources

fsutil::mount_nfs

Mounts a remote NFS share on a local mount point. Options:

• device - remote share to mount
• options (default = 'defaults') - the mount options to use,
• mode (default = 0755) - the mode of the mount point
• umask (default = 0022) - the umask to use when any parent directories get created Any parent directories needed for the mount point (and the mount point itself) will be created and managed by Puppet Example:

fsutil::mount_nfs { '/downloads':
  device  => 'mac:/Users/matt/Downloads',
  options => 'ro,hard,intr',
}

fsutil::mkmount

Creates a full path of directories and sets the mode for a mount point. Options:

• mode (default = 0755) - the mode of the mount point
• umask (default = 0022) - the umask to use when any parent directories get created Example:

fsutil::mkmount {  '/temp':
  mode    => '0777',
  umask   => '0222',
}

fsutil::mkdir_p

Creates a full path of directories. Options:

• umask (default = 0022) - the umask to use when any parent directories get created Example:

fsutil::mkdir_p { '/secrets': 
  umask   => '0200',
}

fsutil::mktree

Creates a full tree of directories. It expands a Hash or Array (or combination) and uses the fsutil::mkmount resource to create the directory. Options:

• umask (default = 0022) - the umask to use when any parent directories get created
• mode (default = 0755) - the mode of the directory Example:

fsutil::mktree { '/secrets': 
  umask   => '0200',
  umask   => '0755',
  tree => { '/repo' => ['baseline', 'packages', {'os' => [{'Centos' => [6, 7]}]}]}],
}

This will create the following directories:

/repo
/repo/baseline
/repo/packages
/repo/os
/repo/os/Centos
/repo/os/Centos/6
/repo/os/Centos/7

Alternatively, you can specify hiera data and include the class:

fsutil::tree:
  repo:
    - baseline
    - packages
    - os:
      - Centos:
        - 6
        - 7

Issues

This module is using hiera data that is embedded in the module rather than using a params class. This may not play nicely with other modules using the same technique unless you are using hiera 3.0.6 and above (PE 2015.3.2+).
