Installation & Usage
Installing in a virtual environment
virtualenv is a tool to create isolated Python environments. The basic problem it addresses is one of dependencies and versions, and indirectly permissions. virtualenv can help you install this client without needing system install permissions. It creates an environment that has its own installation directories without sharing libraries with other virtualenv environments or the system installation.
Mac/Linux
To install virtualenv via pip run:
$ pip3 install virtualenv
Create the virtualenv and activate it
$ virtualenv -p python3 <my-env>
$ source <my-env>/bin/activate
Install the Nutanix client into the virtualenv
<my-env>/bin/pip install ntnx-opsmgmt-py-client
Windows
To install virtualenv via pip run:
> pip install virtualenv
Create the virtualenv and activate it
> virtualenv <my-env>
> myenv\Scripts\activate
Install the Nutanix SDK into the virtualenv
<your-env>\Scripts\pip.exe install ntnx-opsmgmt-py-client
Then import the package:
import ntnx_opsmgmt_py_client

Sample Configuration
config = Configuration()
config.host = '10.19.50.27'
config.port = 9440
config.username = 'admin'
config.password = 'password'
api_client = ApiClient(configuration=config)
Proxy Configuration
config = Configuration()
config.proxy_scheme = "https"
config.proxy_host = "127.0.0.1"
config.proxy_port = 8080
config.proxy_username = "proxy_admin"
config.proxy_password = "proxy_password"
api_client = ApiClient(configuration=config)
mTLS Configuration
config = Configuration()
config.root_ca_certificate_file = "/home/certs/ca.pem"
config.client_certificate_file = "/home/certs/AdonisService/AdonisService.crt"
config.client_key_file = "/home/certs/AdonisService/AdonisService.key"
api_client = ApiClient(configuration=config)
Authentication
Nutanix APIs currently support two type of authentication schemes:
The python client can be configured to send additional headers on each request.
client = ApiClient(configuration=config)
client.add_default_header(header_name='Accept-Encoding', header_value='gzip, deflate, br')
Retry Mechanism
The client can be configured to retry requests that fail with the following status codes. The numbers of seconds before which the next retry is attempted is determined by the retryInterval:
The client will also redirect requests that fail with 302 - Found to the new location specified in the response header Location
.
{backoff factor} * (2 * ({number of retries so far} - 1))
config = Configuration()
config.max_retry_attempts = 3
config.backoff_factor = 3
config.max_redirects = 3
client = ApiClient(configuration=config)
Usage
Invoking an operation
report_config_api_instance = ReportConfigApi(api_client=client)
extId = 'extId_example'
try:
api_response = report_config_api_instance.get_report_config_by_id(extId)
except ApiException as e:
Headers can be configured globally on the python client using the method to set default headers. However, sometimes headers need to be set on an individual operation basis. Nutanix APIs require that concurrent updates are protected using ETag headers.
report_config_api_instance = ReportConfigApi(api_client=client)
extId = 'extId_example'
try:
api_response = report_config_api_instance.get_report_config_by_id(extId)
except ApiException as e:
etag_value = ApiClient.get_etag(api_response)
try:
api_response = report_config_api_instance.update_report_config_by_id(body, extId, if_match=etag_value)
except ApiException as e:
List Operations
List Operations for Nutanix APIs support pagination, filtering, sorting and projections. The table below details the parameters that can be used to set the options for pagination etc.
Parameter | Description |
---|
_page | specifies the page number of the result set. Must be a positive integer between 0 and the maximum number of pages that are available for that resource. Any number out of this range will lead to no results being returned. |
_limit | specifies the total number of records returned in the result set. Must be a positive integer between 0 and 100. Any number out of this range will lead to a validation error. If the limit is not provided a default value of 50 records will be returned in the result set |
_filter | allows clients to filter a collection of resources. The expression specified with $filter is evaluated for each resource in the collection, and only items where the expression evaluates to true are included in the response. Expression specified with the $filter must conform to the OData V4.01 URL conventions. |
_orderby | allows clients to specify the sort criteria for the returned list of objects. Resources can be sorted in ascending order using asc or descending order using desc. If asc or desc are not specified the resources will be sorted in ascending order by default. For example, 'orderby=templateName desc' would get all templates sorted by templateName in desc order. |
_select | allows clients to request a specific set of properties for each entity or complex type. Expression specified with the $select must conform to the OData V4.01 URL conventions. If a $select expression consists of a single select item that is an asterisk (i.e., *), then all properties on the matching resource will be returned. |
_expand | allows clients to request related resources when a resource that satisfies a particular request is retrieved. Each expanded item is evaluated relative to the entity containing the property being expanded. Other query options can be applied to an expanded property by appending a semicolon-separated list of query options, enclosed in parentheses, to the property name. Permissible system query options are $filter,$select and $orderby. |
report_config_api_instance = ReportConfigApi(api_client=client)
extId = 'extId_example'
try:
api_response = report_config_api_instance.list_report_configs(
_page=page,
_limit=limit,
_filter=_filter,
_orderby=_orderby,
_select=select,
_expand=expand)
except ApiException as e:
The list of filterable and sortable fields with expansion keys can be found in the documentation here.
