Module Description

Github Master: Build Status

This module installs, configures and manages everything on NFS clients and servers.

This module is a complete refactor of the module haraldsk/nfs, because Harald Skoglund sadly is not maintaining his module actively anymore. It is stripped down to use only the class 'nfs' and parametrized to act as a server, client or both with the parameters 'server_enabled' and 'client_enabled'. It also has some dependencies on newer stdlib functions like 'difference'.

It supports the OS Families Ubuntu, Debian, Redhat, SUSE, Gentoo and Archlinux. It supports also Strict Variables, so if you pass all OS specific parameters correctly it should work on your preferred OS too. Feedback, bugreports, and feature requests are always welcome, visit https://github.com/derdanne/puppet-nfs or send me an email.

When you are using a puppet version 3.x like it is shipped with Redhat Satellite 6, please use a version 1.x.x from puppet forge or the branch puppet3 when cloning directly from Github. (Note: https://github.com/derdanne/puppet-nfs/pull/49#issuecomment-285091678). I'll recommend using puppet >= 4.6.1, puppet versions up until 4.6.0 had various issues.

If you want to contribute, please do a fork on github, create a branch "feature name" with your features and do a pull request.

Warning: I've introduced new dependencies with version 2.1.0 which were needed to fix buggy rpcbind-socket restarting with systemd:

  • puppetlabs/transition
  • herculesteam/augeasproviders_core
  • herculesteam/augeasproviders_shellvar

Setup

What derdanne-nfs affects

This module can be used to configure your nfs client and/or server, it could export nfs mount resources via storeconfigs or simply mount nfs shares on a client. You can also easily use the create_resources function when you store your exports i.e. via hiera.

Setup requirements

This Module depends on puppetlabs-stdlib >= 4.5.0 and puppetlabs-concat >= 1.1.2, you need to have these modules installed to use derdanne-nfs module.

Beginning with derdanne-nfs

On a nfs server the following code is sufficient to get all packages installed and services running to use nfs:

  node server {
    class { '::nfs':
      server_enabled => true,
    }
  }

On a client the following code is sufficient:

  node server {
    class { '::nfs':
      client_enabled => true,
    }
  }

Usage

Simple NFSv3 server and client example

This will export /data/folder on the server and automagically mount it on client.

  node server {
    class { '::nfs':
      server_enabled => true
    }
    nfs::server::export{ '/data_folder':
      ensure  => 'mounted',
      clients => '10.0.0.0/24(rw,insecure,async,no_root_squash) localhost(rw)'
    }
  }

  # By default, mounts are mounted in the same folder on the clients as
  # they were exported from on the server
  node client {
    class { '::nfs':
      client_enabled => true,
    }
    Nfs::Client::Mount <<| |>>
  }

Simple NFSv4 client example

This will mount /data on client in /share/data.

  node client {
    class { '::nfs':
      server_enabled => false,
      client_enabled => true,
      nfs_v4_client => true,
      nfs_v4_idmap_domain => $::domain,
    }
  
    nfs::client::mount { '/share/data':
        server => '192.168.0.1',
        share => 'data',
    }
  }

NFSv3 multiple exports, servers and multiple node example

  node server1 {
    class { '::nfs':
      server_enabled => true,
    }
    nfs::server::export { '/data_folder':
      ensure  => 'mounted',
      clients => '10.0.0.0/24(rw,insecure,async,no_root_squash) localhost(rw)',
    }
    nfs::server::export { '/homeexport':
      ensure  => 'mounted',
      clients => '10.0.0.0/24(rw,insecure,async,root_squash)',
      mount   => '/srv/home',
    }
  }

  node server2 {
    class { '::nfs':
      server_enabled => true,
    }
    # ensure is passed to mount, which will make the client not mount it
    # the directory automatically, just add it to fstab
    nfs::server::export { '/media_library':
      ensure  => 'present',
      nfstag     => 'media',
      clients => '10.0.0.0/24(rw,insecure,async,no_root_squash) localhost(rw)',
    }
  }

  node client {
    class { '::nfs':
      client_enabled => true,
    }
    Nfs::Client::Mount <<| |>>
  }

  # Using a storeconfig override, to change ensure option, so we mount
  # all shares
  node greedy_client {
    class { '::nfs':
      client_enabled => true,
    }
    Nfs::Client::Mount <<| |>> {
      ensure => 'mounted',
    }
  }


  # only the mount tagged as media
  # also override mount point
  node media_client {
    class { '::nfs':
      client_enabled => true,
    }
    Nfs::Client::Mount <<| nfstag == 'media' |>> {
      ensure => 'mounted',
      mount  => '/import/media',
    }
  }

  # All @@nfs::server::mount storeconfigs can be filtered by parameters
  # Also all parameters can be overridden (not that it's smart to do
  # so).
  # Check out the doc on exported resources for more info:
  # http://docs.puppetlabs.com/guides/exported_resources.html
  node single_server_client {
    class { '::nfs':
      client_enabled => true,
    }
    Nfs::Client::Mount <<| server == 'server1' |>> {
      ensure => 'absent',
    }
  }

NFSv4 Simple example

  # We use the $::domain fact for the Domain setting in
  # /etc/idmapd.conf.
  # For NFSv4 to work this has to be equal on servers and clients
  # set it manually if unsure.
  #
  # All nfsv4 exports are bind mounted into /export/$mount_name
  # and mounted on /srv/$mount_name on the client.
  # Both values can be overridden through parameters both globally

  # and on individual nodes.
  node server {
    file { ['/data_folder', '/homeexport']:
      ensure => 'directory',
    }
    class { '::nfs':
      server_enabled => true,
      nfs_v4 => true,
      nfs_v4_idmap_domain => 'example.com',
      nfs_v4_export_root  => '/export',
      nfs_v4_export_root_clients => '*(rw,fsid=0,insecure,no_subtree_check,async,no_root_squash)',
    }
    nfs::server::export { '/data_folder':
      ensure  => 'mounted',
      clients => '*(rw,insecure,async,no_root_squash,no_subtree_check)',
    }
    nfs::server::export { '/homeexport':
      ensure  => 'mounted',
      clients => '*(rw,insecure,async,root_squash,no_subtree_check)',
      mount   => '/srv/home',
    }
  }

  # By default, mounts are mounted in the same folder on the clients as
  # they were exported from on the server

  node client {
    class { '::nfs':
      client_enabled  => true,
      nfs_v4_client   => true,
    }
    Nfs::Client::Mount <<| |>>
  }

  # We can also mount the NFSv4 Root directly through nfs::client::mount::nfsv4::root.
  # By default /srv will be used for as mount point, but can be overriden through
  # the 'mounted' option.

  node client2 {
    $server = 'server'
    class { '::nfs':
      client_enabled => true,
      nfs_v4_client  => true,
    }
    Nfs::Client::Mount::Nfs_v4::Root <<| server == $server |>> {
      mount => "/srv/${server}",
    }
  }

Requirements

Modules needed:

Software versions needed:

facter > 1.6.2 puppet > 3.2.0

Ruby Gems needed:

augeas

Limitations

If you want to have specific package versions installed you may manage the needed packages outside of this module (use manage_packages => false). It is only tested to use 'present', 'installed', 'absent', 'purged', 'held' and 'latest' as argument for the parameters server_package_ensure and client_package_ensure.

Development

Derdanne modules are open projects. So if you want to make this module even better, you can contribute to this module on Github.

Before pushing PRs to Github i would recommend you to test your work locally. So you can ensure all test builds on Travis CI were passing. I have prepared an easy way to test your code locally with the help of Docker.

For running the complete static code analysis, it is sufficient to run a make test-all.

Default settings

I have set some defaults which you can change by setting the following environment variables.

PUPPET_VERSION

Changes the puppet version which will be used for the tests. Defaults to 6.0.

STRICT_VARIABLES
