yaml – Uses a specific YAML file as an inventory source

New in version 2.4.


Synopsis

  • YAML-based inventory, should start with the all group and contain hosts/vars/children entries.
  • Host entries can have sub-entries defined, which will be treated as variables.
  • Vars entries are normal group vars.
  • Children are ‘child groups’, which can also have their own vars/hosts/children and so on.
  • File MUST have a valid extension, defined in configuration.

Parameters

Parameter Choices/Defaults Configuration Comments

yaml_extensions

list

Default:

[".yaml", ".yml", ".json"]

ini entries: [defaults]yaml_valid_extensions = ['.yaml', '.yml', '.json']

[inventory_plugin_yaml]yaml_valid_extensions = ['.yaml', '.yml', '.json']


env:ANSIBLE_YAML_FILENAME_EXT

env:ANSIBLE_INVENTORY_PLUGIN_EXTS

Notes

Note

  • If you want to set vars for the all group inside the inventory file, the all group must be the first entry in the file.
  • Whitelisted in configuration by default.


Examples

all: # keys must be unique, i.e. only one 'hosts' per group
    hosts:
        test1:
        test2:
            host_var: value
    vars:
        group_all_var: value
    children:   # key order does not matter, indentation does
        other_group:
            children:
                group_x:
                    hosts:
                        test5   # Note that one machine will work without a colon
                #group_x:
                #    hosts:
                #        test5  # But this won't
                #        test7  #
                group_y:
                    hosts:
                        test6:  # So always use a colon
            vars:
                g2_var2: value3
            hosts:
                test4:
                    ansible_host: 127.0.0.1
        last_group:
            hosts:
                test1 # same host as above, additional group membership
            vars:
                group_last_var: value

Hint

If you notice any issues in this documentation, you can edit this document to improve it.


Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
