Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

hostsfile LWRP

Build Status

hostsfile provides an LWRP for managing your /etc/hosts (or Windows equivalent) file using Chef.


  • Chef 11 or higher
  • Ruby 1.9.3 or higher

Please stop opening Pull Requests to restore Ruby 1.8 support! Any of the 1.x.y series of this cookbook will work with Chef 10 and Ruby 1.8. You can use Opscode's Omnibus installer to install Ruby 1.9+ and Seth Chisamore's Vagrant Omnibus plugin to get Ruby 1.9+ on your Vagrant box.


<td>(name attribute) the IP address for the entry</td>
<td>(required) the hostname associated with the entry</td>
<td>remove any existing entries that have the same <tt>hostname</tt></td>
<td>array of aliases for the entry</td>
<td>a comment to append to the end of the entry</td>
<td><tt>'interal DNS server'</tt></td>
<td>the relative position of this entry</td>
<td>(varies, see Priorities section)</td>


Please note: In v0.1.2, specifying a hostname or alias that existed in another automatically removed that hostname from the other entry before. In v2.1.0, the unique option was added to give the user case-by-case control of this behavior. For example, given an /etc/hosts file that contains:

when the Chef recipe below is converged:

hostsfile_entry '' do
  hostname  ''
  unique    true

then the /etc/hosts file will look like this:

Not specifying the unique parameter will result in duplicate hostsfile entries.


Creates a new hosts file entry. If an entry already exists, it will be overwritten by this one.

hostsfile_entry '' do
  hostname  ''
  action    :create

This will create an entry like this:


Create a new hosts file entry, only if one does not already exist for the given IP address. If one exists, this does nothing.

hostsfile_entry '' do
  hostname  ''
  action    :create_if_missing


Append a hostname or alias to an existing record. If the given IP address doesn't not already exist in the hostsfile, this method behaves the same as create. Otherwise, it will append the additional hostname and aliases to the existing entry. # Created by Chef
hostsfile_entry '' do
  hostname  ''
  aliases   ['', '']
  comment   'Append by Recipe X'
  action    :append

would yield: # Created by Chef, Appended by Recipe X


Updates the given hosts file entry. Does nothing if the entry does not exist.

hostsfile_entry '' do
  hostname  ''
  comment   'Update by Chef'
  action    :update

This will create an entry like this:           example # Updated by Chef


Removes an entry from the hosts file. Does nothing if the entry does not

hostsfile_entry '' do
  action    :remove

This will remove the entry for


If you're using Berkshelf, just add hostsfile to your Berksfile:

cookbook 'hostsfile'

Otherwise, install the cookbook from the community site:

knife cookbook site install hostsfile

Have any other cookbooks depend on hostsfile by editing editing the metadata.rb for your cookbook.

# metadata.rb
depends 'hostsfile'

Note that you can specify a custom path to your hosts file in the ['hostsfile']['path'] node attribute. Otherwise, it defaults to sensible paths depending on your OS.


If you are using ChefSpec to unit test a cookbook that implements the hostsfile_entry LWRP, this cookbook packages customer matchers that you can use in your unit tests:

  • append_hostsfile_entry
  • create_hostsfile_entry
  • create_hostsfile_entry_if_missing
  • remove_hostsfile_entry
  • update_hostsfile_entry

For example:

it 'creates a hostsfile entry for the DNS server' do
  expect(chef_run).to create_hostsfile_entry('')


Priority is a relatively new addition to the cookbook. It gives you the ability to (somewhat) specify the relative order of entries. By default, the priority is calculated for you as follows:

  1. Local, loopback
  2. IPV4
  3. IPV6

However, you can override it using the priority option.


  1. Fork the project
  2. Create a feature branch corresponding to you change
  3. Commit and test thoroughly
  4. Create a Pull Request on github
