python-ecsclient

This library is the Python Software Development Kit (SDK) for Dell EMC ECS. It allows developers to interact with the ECS Management API. You can find the ECS API specification here.

This library is the successor of ECS Minion.

Quick Start

You can install python-ecsclient using pip.

$ pip install python-ecsclient

Creating an instance of the ECSClient class allows the following arguments:

Name	Required	Default Value	Description
version	Yes	None	Version of the target ECS system. Options are 2 and 3
username	No	None	The username used to fetch the ECS token
password	No	None	The password used to fetch the ECS token
token	No	None	Pass a token to ECSClient (username/password are ignored then)
ecs_endpoint	Yes	None	The ECS API endpoint, ex: https://192.168.0.149:4443
token_endpoint	No	None	The ECS API endpoint, ex: https://192.168.0.149:4443/login
verify_ssl	No	False	Whether to check a host's SSL certificate
token_path	No	/tmp/ecsclient.tkn	The location to store the temporary token file
request_timeout	No	15.0	Stop waiting for a response after a given number of seconds, this is a decimal value. Ex: 10.0 is ten seconds
cache_token	No	True	Whether to cache the token, by default this is true you should only switch this to false when you want to directly fetch a token for a user

cache_token | No | True | Whether to cache the token, by default this is true you should only switch this to false when you want to directly fetch a token for a user |

This is how you can instantiate the Client class and use the library.

from ecsclient.client import Client

client = Client('3',
                username='ecsadmin@internal',
                password='PASSWORD',
                token_endpoint='https://192.168.0.149:4443/login',
                ecs_endpoint='https://192.168.0.149:4443')

print(client.user_info.whoami())

Take a look at our documentation to find a list of all supported ECS endpoints and services.

Supply a token

You can pass an authentication token directly to the client which means you don't need to supply a username/password.

client = Client('3',
                token='ALAcbGZtbjh6eVB3eUF1TzFEZWNmc0M2VVl2QjBVPQM',
                ecs_endpoint='https://192.168.1.146:4443')

Token caching

By default, the client caches the auth token. But you can disable caching by setting the cache_token parameter to false.

client = Client('3',
                username='someone',
                password='password',
                token_endpoint='https://192.168.1.146:4443/login',
                ecs_endpoint='https://192.168.1.146:4443',
                cache_token=False)

Alternatively, when token caching is enabled, you may want to force the client to obtain a new token on the next call. To do so, you can remove the cached token.

client.remove_cached_token()

Add X-EMC-Override: "true" header

You can pass override_header to the client which means the user wants to add custom X-EMC-Override header into API request

client = Client('3',
                username='someone',
                password='password',
                token_endpoint='https://192.168.1.146:4443/login',
                ecs_endpoint='https://192.168.1.146:4443',
                override_header='true')

Development

Getting Started

Assuming that you have Python and virtualenv installed, set up your environment and install the required dependencies like this instead of the pip install python-ecsclient defined above:

$ git clone https://github.com/EMCECS/python-ecsclient.git
$ cd python-ecsclient
$ virtualenv venv
...
$ . venv/bin/activate
$ pip install -r requirements.txt

Running Tests

You can run tests in all supported Python versions using tox. By default, it will run all of the unit tests, but you can also specify your own nosetests options. Note that this requires that you have all supported versions of Python installed, otherwise you must pass -e or run the nosetests command directly:

$ tox
$ tox -e py27,py35 tests/functional

You can also run individual tests with your default Python version:

$ nosetests tests/unit
