aci_rest – Direct access to the Cisco APIC REST API

New in version 2.4.

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.
