Synopsis ¶

Enables the management of the Cisco ACI fabric through direct access to the Cisco APIC REST API.
Thanks to the idempotent nature of the APIC, this module is idempotent and reports changes.

Requirements ¶

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

lxml (when using XML payload)
xmljson >= 0.1.8 (when using XML payload)
python 2.7+ (when using xmljson)

Parameters ¶

Parameter	Choices/Defaults	Comments
certificate_name -		The X.509 certificate name attached to the APIC AAA user used for signature-based authentication. It defaults to the `private_key` basename, without extension. aliases: cert_name
content -		When used instead of `src`, sets the payload of the API request directly. This may be convenient to template simple requests. For anything complex use the `template` lookup plugin (see examples) or the template module with parameter `src`.
host - / required		IP Address or hostname of APIC resolvable by Ansible control host. aliases: hostname
method -	Choices: delete get ← post	The HTTP method of the request. Using `delete` is typically used for deleting objects. Using `get` is typically used for querying objects. Using `post` is typically used for modifying objects. aliases: action
output_level -	Choices: debug info normal ←	Influence the output of this ACI module. `normal` means the standard output, incl. `current` dict `info` adds informational output, incl. `previous`, `proposed` and `sent` dicts `debug` adds debugging output, incl. `filter_string`, `method`, `response`, `status` and `url` information
password - / required		The password to use for authentication. This option is mutual exclusive with `private_key`. If `private_key` is provided too, it will be used instead.
path - / required		URI being used to execute API calls. Must end in `.xml` or `.json`. aliases: uri
port -		Port number to be used for REST connection. The default value depends on parameter `use_ssl`.
private_key - / required		PEM formatted file that contains your private key to be used for signature-based authentication. The name of the key (without extension) is used as the certificate name in ACI, unless `certificate_name` is specified. This option is mutual exclusive with `password`. If `password` is provided too, it will be ignored. aliases: cert_key
src path		Name of the absolute path of the filname that includes the body of the HTTP request being sent to the ACI fabric. If you require a templated payload, use the `content` parameter together with the `template` lookup plugin, or use template. aliases: config_file
timeout integer	Default: 30	The socket level timeout in seconds.
use_proxy boolean	Choices: no yes ←	If `no`, it will not use a proxy, even if one is defined in an environment variable on the target hosts.
use_ssl boolean	Choices: no yes ←	If `no`, an HTTP connection will be used instead of the default HTTPS connection.
username -	Default: "admin"	The username to use for authentication. aliases: user
validate_certs boolean	Choices: no yes ←	If `no`, SSL certificates will not be validated. This should only set to `no` when used on personally controlled sites using self-signed certificates.

Notes ¶

Note

Certain payloads are known not to be idempotent, so be careful when constructing payloads, e.g. using status="created" will cause idempotency issues, use status="modified" instead. More information in the ACI documentation.
Certain payloads (and used paths) are known to report no changes happened when changes did happen. This is a known APIC problem and has been reported to the vendor. A workaround for this issue exists. More information in the ACI documentation.
XML payloads require the lxml and xmljson python libraries. For JSON payloads nothing special is needed.
More information regarding the APIC REST API is available from the Cisco APIC REST API Configuration Guide.
