Redfish Python Library

Project description <nav class="contents" id="contents" role="doc-toc">




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 GET, POST, PUT, PATCH and DELETE HTTP operations on resources within a Redfish service. Go to the wiki for more details.


pip install redfish

Building from zip file source

python sdist --formats=zip (this will produce a .zip file)
cd dist
pip install


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:


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.

Import the relevant Python module

For a Redfish conformant application import the relevant Python module.

For Redfish conformant application:

import redfish

Create a Redfish object

The Redfish object contains three required parameters:

  • base_url: The address of the Redfish service (with scheme). Example: For Unix sockets, use the scheme http+unix://, followed by the percent-encoded filepath to the socket.

  • username: The username for authentication.

  • password: The password for authentication.

There are several optional parameters:

  • default_prefix: The path to the Redfish service root. This is only used for initial connection and authentication with the service. The default value is /redfish/v1/.

  • sessionkey: The session key to use with subsequent requests. This can be used to bypass the login step. The default value is None.

  • cafile: The file path to the CA certificate that issued the Redfish service’s certificate. The default value is None.

  • timeout: The number of seconds to wait for a response before closing the connection. The default value is None.

  • max_retry: The number of retries to perform an operation before giving up. The default value is 10.

  • proxies: A dictionary containing protocol to proxy URL mappings. The default value is None. See Using proxies.

To crete a Redfish object, call the redfish_client method:

REDFISH_OBJ = redfish.redfish_client(base_url=login_host, username=login_account, \
                      password=login_password, default_prefix='/redfish/v1/')

Login to the service

After creating the REDFISH_OBJ, perform the login operation to authenticate with the service. The auth parameter allows you to specify the login method. Possible values are:

  • session: Creates a Redfish session with a session token.

  • basic: Uses HTTP Basic authentication for all requests.


Perform a GET operation

A simple GET operation can be performed to obtain the data present in any valid path. An example of GET operation on the path “/redfish/v1/systems/1” is shown below:

response = REDFISH_OBJ.get("/redfish/v1/systems/1", None)

Perform a POST operation

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:

body = {"ResetType": "GracefulShutdown"}
response ="/redfish/v1/systems/1/Actions/ComputerSystem.Reset", body=body)

Working with tasks

A POST and PATCH operations 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 that can be accessed reviewed when polled with monitor. An example of a POST operation with a possible task is shown below.

body = {"ResetType": "GracefulShutdown"}
response ="/redfish/v1/systems/1/Actions/ComputerSystem.Reset", body=body)
    task = response.monitor(context)

        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

Ensure you perform a logout operation when done interacting with the Redfish service. If this step isn’t performed, the session will remain active until the Redfish service decides to close it.


The logout operation deletes the current sesssion from the service. The redfish_client object destructor includes a logout statement.

Using proxies

There are two methods for using proxies: configuring environment variables or directly providing proxy information.

Environment variables

You can use a proxy by specifying the 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=""
export HTTPS_PROXY=""

Directly provided

You can use a proxy by building a dictionary containing the proxy information and providing it to the proxies argument when creating the redfish_client object. The key-value pairs of the dictionary contain the protocol and the proxy URL for the protocol.

proxies = {
    'http': '',
    'https': '',
REDFISH_OBJ = redfish.redfish_client(base_url=login_host, username=login_account, \
                      password=login_password, proxies=proxies)

SOCKS proxy support

An additional package is required to use SOCKS proxies.

pip install -U requests[socks]

Once installed, the proxy can be configured using environment variables or directly provided like any other proxy. For example:

export HTTP_PROXY="socks5h://localhost:8123"
export HTTPS_PROXY="socks5h://localhost:8123"
