The static grains, these are the core, or built in grains.
When grains are loaded they are not loaded in the same way that modules are loaded, grain functions are detected and executed, the functions MUST return a dict which will be applied to the main grains dict. This module will always be executed first, so that any grains loaded here in the core module can be overwritten just by returning dict keys with the same value as those returned here
Populates grains which describe whether a server has a default gateway configured or not. Uses ip -4 route show and ip -6 route show and greps for a default at the beginning of any line. Assuming the standard default via <ip> format for default gateways, it will also parse out the ip address of the default gateway, and put it in ip4_gw or ip6_gw.
If the ip command is unavailable, no grains will be populated.
Currently does not support multiple default gateways. The grains will be set to the first default gateway found.
List of grains:
ip4_gw: True # ip/True/False if default ipv4 gateway ip6_gw: True # ip/True/False if default ipv6 gateway ip_gw: True # True if either of the above is True, False otherwise
Return all known FQDNs for the system by enumerating all interfaces and then trying to reverse resolve them (excluding 'lo' interface). To disable the fqdns grain, set enable_fqdns_grains: False in the minion configuration file.
Provides the minion with the name of its master. This is useful in states to target other services running on the master.
Provides an integer based on the FQDN of a machine. Useful as server-id in MySQL replication or anywhere else you'll need an ID like this.
Return fqdn, hostname, domainname
Note
On Windows the domain
grain may refer to the dns entry for the host
instead of the Windows domain to which the host is joined. It may also
be empty if not a part of any domain. Refer to the windowsdomain
grain instead
Provide a dict of the connected interfaces and their hw addresses (Mac Address)
Provide a dict of the connected interfaces and their ip4 addresses The addresses will be passed as a list for each interface
Provide a dict of the connected interfaces and their ip6 addresses The addresses will be passed as a list for each interface
