Management of addresses and names in hosts file
===============================================
The ``/etc/hosts`` file can be managed to contain definitions for specific hosts:
.. code-block:: yaml
salt-master:
host.present:
- ip: 192.168.0.42
Or using the ``names`` directive, you can put several names for the same IP.
(Do not try one name with space-separated values).
.. code-block:: yaml
server1:
host.present:
- ip: 192.168.0.42
- names:
- server1
- florida
.. note::
Changing the ``names`` in ``host.present`` does not cause an
update to remove the old entry.
.. code-block:: yaml
server1:
host.present:
- ip:
- 192.168.0.42
- 192.168.0.43
- 192.168.0.44
- names:
- server1
You can replace all existing names for a particular IP address:
.. code-block:: yaml
127.0.1.1:
host.only:
- hostnames:
- foo.example.com
- foo
Or delete all existing names for an address:
.. code-block:: yaml
203.0.113.25:
host.only:
- hostnames: []
