Parameters

Parameter Choices/Defaults Comments
action
-
    Choices:
  • add
  • remove
  • set ←
Controls the behavior of aliases.
Only applicable when state=present.
If add, each alias in aliases will be added to the host entry.
If set, each alias in aliases will be added to the host entry, and other aliases will be removed from the entry.
aliases
-
A list of additional names (cname records) for the host entry.
Only applicable when state=present.
canonical_name
-
A canonical name for the host entry.
required for state=present.
ip_address
-
The ip address for the host entry.
Can be either IPv4 (A record) or IPv6 (AAAA record).
Required for state=present.
state
-
    Choices:
  • absent
  • present ←
Whether the entry should be present or absent.
If only canonical_name is provided when state=absent, then all hosts entries with the canonical name of canonical_name will be removed.
If only ip_address is provided when state=absent, then all hosts entries with the ip address of ip_address will be removed.
If ip_address and canonical_name are both omitted when state=absent, then all hosts entries will be removed.

Notes

Note

  • Each canonical name can only be mapped to one IPv4 and one IPv6 address. If canonical_name is provided with state=present and is found to be mapped to another IP address that is the same type as, but unique from ip_address, then canonical_name and all aliases will be removed from the entry and added to an entry with the provided IP address.
  • Each alias can only be mapped to one canonical name. If aliases is provided with state=present and an alias is found to be mapped to another canonical name, then the alias will be removed from the entry and added to or removed from (based on action) an entry with the provided canonical name.
