Synopsis

  • Reads servers from Hetzner Robot API.

  • Uses a YAML configuration file that ends with robot.yml or robot.yaml.

  • The inventory plugin adds all values from https://robot.your-server.de/doc/webservice/en.html#get-server prepended with hrobot_ to the server’s inventory. For example, the variable hrobot_dc contains the data center the server is located in.

The password for the Robot webservice user.

env:HROBOT_API_USER
The username for the Robot webservice user.
keyed_groups
list / elements=dictionary
Default:
[]
Add hosts to group based on the values of a variable.
default_value
string
added in 2.12 of ansible.builtin
The default value when the host variable's value is an empty string.
This option is mutually exclusive with trailing_separator.
key
string
The key from input dictionary used to generate groups
parent_group
string
parent group for keyed group
prefix
string
Default:

trailing_separator
boolean
added in 2.12 of ansible.builtin
    Choices:
  • no
  • yes ←
Set this option to False to omit the separator after the host variable when the value is an empty string.
This option is mutually exclusive with default_value.
leading_separator
boolean
added in 2.11 of ansible.builtin
    Choices:
  • no
  • yes ←
Use in conjunction with keyed_groups.
By default, a keyed group that does not have a prefix or a separator provided will have a name that starts with an underscore.
This is because the default prefix is "" and the default separator is "_".
Set this option to False to omit the leading underscore (or other separator) if no prefix is given.
If the group name is derived from a mapping the separator is still used to concatenate the items.
To not use a separator in the group name at all, set the separator for the keyed group to an empty string instead.

  • community.hrobot.robot
Token that ensures this is a source file for the plugin.
strict
boolean
    Choices:

Since it is possible to use facts in the expressions they might not always be available and we ignore those errors by default.
use_extra_vars

added in 2.11 of ansible.builtin
    Choices:
  • no ←
  • yes
ini entries:

[inventory_plugins]
use_extra_vars = no
