imc_rest – Manage Cisco IMC hardware through its REST API

New in version 2.4.

Synopsis

Requirements

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

  • lxml

  • xmljson >= 0.1.8

Parameters

Parameter Choices/Defaults Comments
content
-
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 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
- / required
IP Address or hostname of Cisco IMC, resolvable by Ansible control host.

aliases: host, ip
password
-
Default:
"password"
The password to use for authentication.
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.

aliases: src, config_file
protocol
-
    Choices:
  • http
  • https ←
Connection protocol to use.
timeout
-
Default:
60
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.
username
-
Default:
"admin"
Username used to login to the switch.

aliases: user
validate_certs
boolean
    Choices:
  • no
  • yes ←
If no, SSL certificates will not be validated.
This should only set to no used on personally controlled sites using self-signed certificates.

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.

  • 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
