# 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
##all:
## hosts:
## green.example.com:
## ansible_ssh_host: 191.168.100.32
## anyvariable: value
## blue.example.com:
## 192.168.100.1:
## 192.168.100.10:
# Ex 2: A collection of hosts belonging to the 'webservers' group, with shared group var
##webservers:
## hosts:
## alpha.example.org:
## beta.example.org:
## 192.168.1.100:
## 192.168.1.110:
## vars:
## http_port: 8080
# Ex 3: You can create hosts using ranges and add children groups and vars to a group
# The child group can define anything you would normally add to a group.
# Hosts in child groups inherit all variables from parent, parents include all hosts in child groups.
# webservers is added as a child group of testing, so all gamma hosts (1-3) are added
# to the 'webservers' group, including gamma3, which is defined in the tree of another parent group.
# All references to webservers will get any hosts defined under webservers.
# References to testing will get all of those hosts plus any host matching www[001:006].example.com
##webservers:
## hosts:
## gamma1.example.org:
## gamma2.example.org:
##testing:
## hosts:
## www[001:006].example.com:
## vars:
## testing1: value1
## children:
## webservers:
##other:
## children:
## webservers:
## gamma3.example.org
# From above, the testing group contains: gamma1.example.org gamma2.example.org gamma3.example.org www001.example.com www002.example.com www003.example.com www004.example.com www005.example.com www006.example.com
# Ex 4: all vars
# keeping within 'all' group you can define common 'all' vars here with lowest precedence
##all:
## vars:
## commontoall: thisvar
