netapp.ontap.na_ontap_restit module – NetApp ONTAP Run any REST API on ONTAP

Note

This module is part of the netapp.ontap collection (version 22.7.0).

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 netapp.ontap. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: netapp.ontap.na_ontap_restit.

New in netapp.ontap 20.4.0

Synopsis

  • Call a REST API on ONTAP.

  • Cluster REST API are run using a cluster admin account.

  • Vserver REST API can be run using a vsadmin account or using vserver tunneling (cluster admin with vserver_ options).

  • In case of success, a json dictionary is returned as response.

  • In case of a REST API error, status_code, error_code, error_message are set to help with diagnosing the issue,

  • and the call is reported as an error (‘failed’).

  • Other errors (eg connection issues) are reported as Ansible error.

Requirements

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

  • Ansible 2.9 or later - 2.12 or later is recommended.

  • Python3 - 3.9 or later is recommended.

  • When using ZAPI, netapp-lib 2018.11.13 or later (install using ‘pip install netapp-lib’), netapp-lib 2020.3.12 is strongly recommended as it provides better error reporting for connection issues

  • a physical or virtual clustered Data ONTAP system, the modules support Data ONTAP 9.1 and onward, REST support requires ONTAP 9.6 or later

Parameters

Parameter

Comments

accept_header

string

added in netapp.ontap 21.24.0

Value for the Accept request HTTP header.

This is very infrequently needed, but required to read a file (see examples).

For most cases, omit this field. Set it to “multipart/form-data” when expecting such a format.

By default the module is using “application/json” or “application/hal+json” when hal_linking is true.

api

string / required

The REST API to call (eg cluster/software, svms/svm).

body

aliases: info

dictionary

A dictionary for the info parameter

cert_filepath

string

added in netapp.ontap 20.6.0

path to SSL client cert file (.pem).

not supported with python 2.6.

feature_flags

dictionary

added in netapp.ontap 20.5.0

Enable or disable a new feature.

This can be used to enable an experimental feature or disable a new feature that breaks backward compatibility.

Supported keys and values are subject to change without notice. Unknown keys are ignored.

files

dictionary

added in netapp.ontap 21.24.0

A dictionary for the parameters when using multipart/form-data.

This is very infrequently needed, but required to write a file (see examples)

When present, requests will automatically set the Content-Type header to multipart/form-data.

force_ontap_version

string

added in netapp.ontap 21.23.0

Override the cluster ONTAP version when using REST.

The behavior is undefined if the version does not match the target cluster.

This is provided as a work-around when the cluster version cannot be read because of permission issues. See https://github.com/ansible-collections/netapp.ontap/wiki/Known-issues.

This should be in the form 9.10 or 9.10.1 with each element being an integer number.

When use_rest is set to auto, this may force a switch to ZAPI based on the version and platform capabilities.

Ignored with ZAPI.

hal_linking

boolean

if true, HAL-encoded links are returned in the response.

Choices:

  • false ← (default)

  • true

hostname

string / required

The hostname or IP address of the ONTAP instance.

http_port

integer

Override the default port (80 or 443) with this port

https

boolean

Enable and disable https.

Ignored when using REST as only https is supported.

Ignored when using SSL certificate authentication as it requires SSL.

Choices:

  • false ← (default)

  • true

key_filepath

string

added in netapp.ontap 20.6.0

path to SSL client key file.

method

string

The REST method to use.

Default: "GET"

ontapi

integer

The ontap api version to use

password

aliases: pass

string

Password for the specified user.

query

dictionary

A list of dictionaries for the query parameters

use_rest

string

Whether to use REST or ZAPI.

always – will always use the REST API if the module supports REST. A warning is issued if the module does not support REST. An error is issued if a module option is not supported in REST.

never – will always use ZAPI if the module supports ZAPI. An error may be issued if a REST option is not supported in ZAPI.

auto – will try to use the REST API if the module supports REST and modules options are supported. Reverts to ZAPI otherwise.

Default: "auto"

username

aliases: user

string

This can be a Cluster-scoped or SVM-scoped account, depending on whether a Cluster-level or SVM-level API is required.

For more information, please read the documentation https://mysupport.netapp.com/NOW/download/software/nmsdk/9.4/.

Two authentication methods are supported

  1. basic authentication, using username and password,

  2. SSL certificate authentication, using a ssl client cert file, and optionally a private key file.

To use a certificate, the certificate must have been installed in the ONTAP cluster, and cert authentication must have been enabled.

validate_certs

boolean

If set to no, the 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)

vserver_name

string

if provided, forces vserver tunneling. username identifies a cluster admin account.

vserver_uuid

string

if provided, forces vserver tunneling. username identifies a cluster admin account.

wait_for_completion

boolean

added in netapp.ontap 21.14.0

when true, POST/PATCH/DELETE can be handled synchronously and asynchronously.

if the response indicates that a job is in progress, the job status is checked periodically until is completes.

when false, the call returns immediately.

Choices:

  • false ← (default)

  • true

Notes

Note

  • The modules prefixed with na_ontap are built to support the ONTAP storage platform.

  • https is enabled by default and recommended. To enable http on the cluster you must run the following commands ‘set -privilege advanced;’ ‘system services web modify -http-enabled true;’
