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.

v0.1.2, specifying a hostname or alias that existed in another automatically removed that hostname from the other entry before. In
unique option was added to give the user case-by-case control of this behavior. For example, given an
/etc/hosts file that contains:
184.108.40.206 example.com www.example.com
when the Chef recipe below is converged:
hostsfile_entry '220.127.116.11' do hostname 'www.example.com' unique true end
/etc/hosts file will look like this:
18.104.22.168 example.com 22.214.171.124 www.example.com
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 '126.96.36.199' do hostname 'example.com' action :create end
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 '188.8.131.52' do hostname 'example.com' action :create_if_missing end
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.
184.108.40.206 example.com www.example.com # Created by Chef
hostsfile_entry '220.127.116.11' do hostname 'www2.example.com' aliases ['foo.com', 'foobar.com'] comment 'Append by Recipe X' action :append end
18.104.22.168 example.com www.example.com www2.example.com foo.com foobar.com # Created by Chef, Appended by Recipe X
Updates the given hosts file entry. Does nothing if the entry does not exist.
hostsfile_entry '22.214.171.124' do hostname 'example.com' comment 'Update by Chef' action :update end
This will create an entry like this:
126.96.36.199 example # Updated by Chef
Removes an entry from the hosts file. Does nothing if the entry does not exist.
hostsfile_entry '188.8.131.52' do action :remove end
This will remove the entry for

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:
it 'creates a hostsfile entry for the DNS server' do expect(chef_run).to create_hostsfile_entry('184.108.40.206') .with_hostname('dns.example.com') end
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:
- Local, loopback
However, you can override it using the
- Fork the project
- Create a feature branch corresponding to you change
- Commit and test thoroughly
- Create a Pull Request on github
