salt.states.host#

Management of addresses and names in hosts file#

The /etc/hosts file can be managed to contain definitions for specific hosts:

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).

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.

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:

127.0.1.1:
  host.only:
    - hostnames:
      - foo.example.com
      - foo

Or delete all existing names for an address:

203.0.113.25:
    host.only:
      - hostnames: []

You can also include comments:

server1:
  host.present:
    - ip: 192.168.0.42
    - names:
      - server1
      - florida
    - comment: A very important comment
