Groups of hosts.
Manage groups of hosts. This is useful for applying access control to a
number of hosts by using Host-based Access Control.
EXAMPLES:
Add a new host group:
ipa hostgroup-add --desc="Baltimore hosts" baltimore
Add another new host group:
ipa hostgroup-add --desc="Maryland hosts" maryland
Add members to the hostgroup:
ipa hostgroup-add-member --hosts=box1,box2,box3 baltimore
Add a hostgroup as a member of another hostgroup:
ipa hostgroup-add-member --hostgroups=baltimore maryland
Remove a host from the hostgroup:
ipa hostgroup-remove-member --hosts=box2 baltimore
Display a host group:
ipa hostgroup-show baltimore
Delete a hostgroup:
ipa hostgroup-del baltimore
