Kiali Python Client

Introduction

This repository includes the necessary Python client libraries to access Kiali remotely

Installation

• To install, run python setup.py install if you installed from source code, or pip install kiali-client if using pip.

Create Client Connections

• To start a Kiali Client, use KialiClient() method. It requires the host, username and password parameters

>>> from kiali import KialiClient
>>> client = KialiClient(host='kiali-url.com')

Another parameters possible to use with Client

• host (default: localhost)
• scheme (default: http, options: https and http
• port (default: 443)
• auth_type (default: https-user-password, options: no-auth; oauth)
• username (default: admin)
• password (default: admin)
• token (use when you are using oauth token. it is the openshift token for the account )
• verify (default: False) - used for verify SSL certificates
• swagger_address (default: Swagger - address to swagger file

Response Metadata

• json
• text
• status_code
• url
• elapsed (Request response time)

Usage Examples:

>>> client.request(method_name='getConfig').json()
{'istioNamespace': 'istio-system', 'istioLabels': {'AppLabelName': 'app', 'VersionLabelName': 'version'}}

>>> client.request(method_name='namespaceList').text
'[{"name":"bookinfo"},{"name":"bookinfo2"},{"name":"default"},{"name":"istio-examples"},{"name":"istio-system"},{"name":"management-infra"}]'

>>> client.request(method_name='namespaceMetrics', path={'namespace': 'istio-system'}).status_code
200

>>> client.request(method_name='jaegerInfo').url
'https://kiali-istio-system.host.com:443/api/jaeger'

>>> client.request(method_name='serviceList', path={'namespace': 'istio-system'}).elapsed
