As of version 3.0.0, Python2 is no longer supported. If Python2 is required, redfish<3.0.0 can be specified in a requirements file.
REST (Representational State Transfer) is a web based software architectural style consisting of a set of constraints that focuses on a system's resources. The Redfish library performs the basic HTTPS operations GET, POST, PUT, PATCH and DELETE on resources using the HATEOAS (Hypermedia as the Engine of Application State) Redfish architecture. API clients allow you to manage and interact with the system through a fixed URL and several URIs. Go to the wiki for more details.
pip install redfish
python setup.py sdist --formats=zip (this will produce a .zip file)
cd dist
pip install redfish-x.x.x.zip
Ensure the system does not have the OpenStack "python-redfish" module installed on the target system. This module is using a conflicting package name that this library already uses. The module in question can be found here: Usage
A set of examples is provided under the examples directory of this project. In addition to the directives present in this paragraph, you will find valuable implementation tips and tricks in those examples.
For a Redfish compliant application import the relevant python module.
For Redfish compliant application:
import redfish
The Redfish Objects contain 3 parameters: the target secured URL (i.e. "
The login operation is performed when creating the REDFISH_OBJ. You can continue with a basic authentication, but it would less secure. A simple GET operation can be performed to obtain the data present in any valid path.
An example of rawget operation on the path "/redfish/v1/systems/1" is shown below: A POST operation can be performed to create a resource or perform an action.
An example of a POST operation on the path "/redfish/v1/systems/1/Actions/ComputerSystem.Reset" is shown below: A POST operation may result in a task, describing an operation with a duration greater than the span of a single request.
The action message object that is_processing will return a Task resource that can be accessed reviewed when polled with monitor.
An example of a POST operation with a possible Task is shown below. Make sure you logout every session you create as it will remain alive until it times out. A logout deletes the current sesssion from the system. The redfish_client object destructor includes a logout statement.

REDFISH_OBJ = redfish.redfish_client(base_url=login_host, username=login_account, \
password=login_password, default_prefix='/redfish/v1')
Login to the server
REDFISH_OBJ.login(auth="session")
Perform a GET operation
response = REDFISH_OBJ.get("/redfish/v1/systems/1", None)
Perform a POST operation
body = {"ResetType": "GracefulShutdown"}
response = REDFISH_OBJ.post("/redfish/v1/systems/1/Actions/ComputerSystem.Reset", body=body)
Working with Tasks
body = {"ResetType": "GracefulShutdown"}
response = REDFISH_OBJ.post("/redfish/v1/systems/1/Actions/ComputerSystem.Reset", body=body)
if(response.is_processing):
task = response.monitor(context)
while(task.is_processing):
retry_time = task.retry_after
task_status = task.dict['TaskState']
time.sleep(retry_time if retry_time else 5)
task = response.monitor(context)
Logout the created session
REDFISH_OBJ.logout()
Using proxies
HTTP_PROXY and HTTPS_PROXY environment variables. Hosts to be excluded from the proxy can be specified using the NO_PROXY environment variable.
export HTTP_PROXY="http://192.168.1.10:8888"
