# This is the default ansible 'hosts' file.
|
|
#
|
|
# It should live in /etc/ansible/hosts
|
|
#
|
|
# - Comments begin with the '#' character
|
|
# - Blank lines are ignored
|
|
# - Top level entries are assumed to be groups, start with 'all' to have a full hierarchy
|
|
# - Hosts must be specified in a group's hosts:
|
|
# and they must be a key (: terminated)
|
|
# - groups can have children, hosts and vars keys
|
|
# - groups are unique and global - if you define a group in multiple locations, Ansible aggregates all the data to the global name.
|
|
# - If you define a group as a child of 2 different groups, it will be the child of both, any hosts and variables assigned will not be dependent on the parents, they will all be associated with the group.
|
|
# - Anything defined under a host is assumed to be a var
|
|
# - You can enter hostnames or IP addresses
|
|
# - A hostname/IP can be a member of multiple groups
|
|
|
|
# Ex 1: Ungrouped hosts, put them in 'all' or 'ungrouped' group, defines 4 hosts, one with 2 variables

# Ex 3: You can create hosts using ranges and add children groups and vars to a group
