community.general.imc_rest module – Manage Cisco IMC hardware through its REST API

Note

This module is part of the community.general collection (version 8.6.7).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.general. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: community.general.imc_rest.

Synopsis 

Provides direct access to the Cisco IMC REST API.
Perform any configuration changes and actions that the Cisco IMC supports.
More information about the IMC REST API is available from http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c/sw/api/3_0/b_Cisco_IMC_api_301.html.

Aliases: remote_management.imc.imc_rest

Requirements 

The below requirements are needed on the host that executes this module.

lxml
xmljson >= 0.1.8

Parameters 

Parameter	Comments
content string	When used instead of `path`, sets the content of the API requests directly. This may be convenient to template simple requests, for anything complex use the ansible.builtin.template module. You can collate multiple IMC XML fragments and they will be processed sequentially in a single stream, the Cisco IMC output is subsequently merged. Parameter `content` is mutual exclusive with parameter `path`.
hostname aliases: host, ip string / required	IP Address or hostname of Cisco IMC, resolvable by Ansible control host.
password string	The password to use for authentication. Default: `"password"`
path aliases: src, config_file path	Name of the absolute path of the filename that includes the body of the http request being sent to the Cisco IMC REST API. Parameter `path` is mutual exclusive with parameter `content`.
protocol string	Connection protocol to use. Choices: `"http"` `"https"` ← (default)
timeout integer	The socket level timeout in seconds. This is the time that every single connection (every fragment) can spend. If this `timeout` is reached, the module will fail with a `Connection failure` indicating that `The read operation timed out`. Default: `60`
username aliases: user string	Username used to login to the switch. Default: `"admin"`
validate_certs boolean	If `false`, SSL certificates will not be validated. This should only set to `false` used on personally controlled sites using self-signed certificates. Choices: `false` `true` ← (default)

Attributes 

Attribute	Support	Description
check_mode	Support: full	Can run in `check_mode` and return changed status prediction without modifying target.
diff_mode	Support: none	Will return details on what has changed (or possibly needs changing in `check_mode`), when in diff mode.

Notes 

Note

The XML fragments don’t need an authentication cookie, this is injected by the module automatically.
The Cisco IMC XML output is being translated to JSON using the Cobra convention.
Any configConfMo change requested has a return status of ‘modified’, even if there was no actual change from the previous configuration. As a result, this module will always report a change on subsequent runs. In case this behaviour is fixed in a future update to Cisco IMC, this module will automatically adapt.
If you get a Connection failure related to The read operation timed out increase the timeout parameter. Some XML fragments can take longer than the default timeout.
