Actions
Please note: As of v0.1.2, specifying a hostname or alias that exists in another entry will remove that hostname from the other entry before adding to this one. For example:
1.2.3.4 example.com www.example.com
and
hostsfile_entry '2.3.4.5' do hostname 'www.example.com' end
would yield an /etc/hosts file like this:
1.2.3.4 example.com
2.3.4.5 www.example.com
create
Creates a new hosts file entry. If an entry already exists, it will be overwritten by this one.
hostsfile_entry '1.2.3.4' do hostname 'example.com' action :create end
This will create an entry like this:
1.2.3.4 example.com
create_if_missing
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 '1.2.3.4' do hostname 'example.com' action :create_if_missing end
append
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.
1.2.3.4 example.com www.example.com # Created by Chef
hostsfile_entry '1.2.3.4' do hostname 'www2.example.com' aliases ['foo.com', 'foobar.com'] comment 'Append by Recipe X' end
would yield:
1.2.3.4 example.com www.example.com www2.example.com foo.com foobar.com # Created by Chef, Appended by Recipe X
update
Updates the given hosts file entry. Does nothing if the entry does not exist.
hostsfile_entry '1.2.3.4' do hostname 'example.com' comment 'Update by Chef' action :update end
This will create an entry like this:
1.2.3.4 example # Updated by Chef
remove
Removes an entry from the hosts file. Does nothing if the entry does not
exist.
hostsfile_entry '1.2.3.4' do action :remove end
This will remove the entry for 1.2.3.4.
Usage
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'
Priority
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
- IPV4
- IPV6
However, you can override it using the priority option.
