## 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 string |  | The X.509 certificate name attached to the APIC AAA user used for signature-based authentication. If a `private_key` filename was provided, this defaults to the `private_key` basename, without extension. If PEM-formatted content was provided for `private_key`, this defaults to the `username` value. aliases: cert_name
content raw |  | 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 string / required |  | IP Address or hostname of APIC resolvable by Ansible control host. aliases: hostname
method string | 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 string | 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 string / 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 string / required |  | URI being used to execute API calls. Must end in `.xml` or `.json`. aliases: uri
port integer |  | Port number to be used for REST connection. The default value depends on parameter `use_ssl`.
private_key string / required |  | Either a PEM-formatted private key file or the private key content used for signature-based authentication. This value also influences the default `certificate_name` that is used. 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 filename 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 string | 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.
