nfs cookbook

Description

Installs and configures NFS client and server components

Maintainers

This cookbook is maintained by the Sous Chefs. The Sous Chefs are a community of Chef cookbook maintainers working together to maintain important cookbooks. If you’d like to know more please visit sous-chefs.org or come chat with us on the Chef Community Slack in #sous-chefs.

Requirements

Should work on any RHEL 7+, Debian 10+, Ubuntu 18.04+ distributions.

This cookbook depends on the line cookbook

Attributes

• nfs['packages']

  • Case switch in attributes to choose NFS client packages dependent on platform.

• nfs['service']

  • ['config'] - only set on Debian/Ubuntu to work around loose systemd dependencies on this platform family - debian: nfs-config.service
  • ['portmap'] - the rpcbind service - default: nfs-client.target
  • ['lock'] - the rpc-statd service - default: nfs-client.target, debian: rpc-statd.service
  • ['server'] - the server component, - default: nfs-server.service, debian: nfs-kernel-server.service
  • ['idmap'] - the NFSv4 idmap component

• nfs['config']

  • client_templates - templates to iterate through on client systems, chosen by platform
  • server_template - Per-platform case switch in common nfs.erb template. This string should be set to where the main NFS server configuration file should be placed.
  • idmap_template - Path to idmapd.conf used in nfs::client4 and nfs::server4 recipes.

• nfs['threads'] - Number of nfsd threads to run. Default 8 on Linux, 24 on FreeBSD. Set to 0, to disable.

• nfs['port']

  • ['statd'] = Listen port for statd, default 32765
  • ['statd_out'] = Outgoing port for statd, default 32766
  • ['mountd'] = Listen port for mountd, default 32767
  • ['lockd'] = Listen port for lockd, default 32768

• nfs['v2'], nfs['v3'], nfs['v4']

  • Set to yes or no to turn on/off NFS protocol level v2, or v3.
  • Defaults to nil, deferring to the default behavior provided by running kernel.

• nfs['mountd_flags'] - BSD launch options for mountd.

• nfs['server_flags'] - BSD launch options for nfsd.

• nfs['idmap']

  • Attributes specific to idmap template and service.
  • ['domain'] - Domain for idmap service, defaults to node['domain']
  • ['pipefs_directory'] - platform-specific location of Pipefs-Directory
  • ['user'] - effective user for idmap service, default nobody.
  • ['group'] - effective group for idmap service, default nogroup.

Usage

To install the NFS components for a client system, simply add nfs to the run list.

name "base"
description "Role applied to all systems"
run_list [ "nfs" ]

Then in an nfs_server.rb role that is applied to NFS servers:

name "nfs_server"
description "Role applied to the system that should be an NFS server."
override_attributes(
  "nfs" => {
    "packages" => [ "portmap", "nfs-common", "nfs-kernel-server" ],
    "port" => {
      "statd" => 32765,
      "statd_out" => 32766,
      "mountd" => 32767,
      "lockd" => 32768
    }
  }
)
run_list [ "nfs::server" ]

nfs_export resource Usage

Applications or other cookbooks can use the nfs_export resource to add exports:

nfs_export "/exports" do
  network '10.0.0.0/8'
  writeable false
  sync true
  options ['no_root_squash']
end

The default parameters for the nfs_export LWRP are as follows

• directory

  • directory you wish to export
  • defaults to resource name

• network

  • a CIDR, IP address, or wildcard (*)
  • requires an option
  • can be a string for a single address or an array of networks

• writeable

  • ro/rw export option
  • defaults to false

• sync

  • synchronous/asynchronous export option
  • defaults to true

• anonuser

  • user mapping for anonymous users
  • the user's UID will be retrieved from /etc/passwd for the anonuid=x option
  • defaults to nil (no mapping)

• anongroup

  • group mapping for anonymous users
  • the group's GID will be retrieved from /etc/group for the anongid=x option
  • defaults to nil (no mapping)

• options

  • additional export options as an array, excluding the parameterized sync/async, ro/rw options, and anoymous mappings
  • defaults to root_squash

nfs::default recipe

The default recipe installs and configures the common components for an NFS client, at an effective protocol level of NFSv3. The Chef resource logic for this is in the nfs::_common recipe, with platform-specific conditional defaults set in the default attributes file.

nfs::client4 recipe

Includes the logic from nfs::_common, and also configures and installs the idmap service to provide an effective protocol level of NFSv4. Effectively the same as running both nfs::_common and nfs::_idmap.

nfs::server recipe

The server recipe includes the common client components from nfs::_common. This also configures and installs the platform-specific server services for an effective protocol level of NFSv3.

nfs::server4 recipe

This recipe includes the common client components from nfs::_common. It also configures and installs the platform-specific server services for an effective protocol level of NFSv4. Effectively the same as running nfs::_common and nfs::_idmap and nfs::server.

nfs::undo recipe

Does your freshly kickstarted/preseeded system come with NFS, when you didn't ask for NFS? This recipe inspired by the annoyances cookbook, will run once to remove NFS from the system. Use a knife command to remove NFS components from your system like so.

knife run_list add $NODE nfs::undo
