Using Sushy¶

To use sushy in a project:

Specifying an authentication type¶

There are three authentication objects. By default we use SessionOrBasicAuth. Authentication Modes: auth.SessionOrBasicAuth: Use session based authentication. If we are unable to create a session we will fallback to basic authentication. auth.BasicAuth: Use basic authentication only. auth.SessionAuth: Use session based authentication only.

import logging

import sushy
from sushy import auth

# Enable logging at DEBUG level
LOG = logging.getLogger('sushy')
LOG.setLevel(logging.DEBUG)
LOG.addHandler(logging.StreamHandler())

basic_auth = auth.BasicAuth(username='foo', password='bar')
session_auth = auth.SessionAuth(username='foo', password='bar')
session_or_basic_auth = auth.SessionOrBasicAuth(username='foo',
                                                password='bar')

s = sushy.Sushy('http://localhost:8000/redfish/v1',
                auth=basic_auth)

s = sushy.Sushy('http://localhost:8000/redfish/v1',
                auth=session_auth)

s = sushy.Sushy('http://localhost:8000/redfish/v1',
                auth=session_or_basic_auth)

# It is important to note that you can
# call sushy without supplying an
# authentication object. In that case we
# will use the SessionOrBasicAuth authentication
# object in an attempt to connect to all different
# types of redfish servers.
s = sushy.Sushy('http://localhost:8000/redfish/v1',
                username='foo',
                password='bar')

Creating and using a sushy system object¶

import logging

import sushy

# Enable logging at DEBUG level
LOG = logging.getLogger('sushy')
LOG.setLevel(logging.DEBUG)
LOG.addHandler(logging.StreamHandler())

s = sushy.Sushy('http://localhost:8000/redfish/v1',
                username='foo', password='bar')

# Get the Redfish version
print(s.redfish_version)

# Instantiate a system object
sys_inst = s.get_system('/redfish/v1/Systems/437XR1138R2')


# Using system collections


# Instantiate a SystemCollection object
sys_col = s.get_system_collection()

# Print the ID of the systems available in the collection
print(sys_col.members_identities)

# Get a list of systems objects available in the collection
sys_col_insts = sys_col.get_members()

# Instantiate a system object, same as getting it directly
# from the s.get_system()
sys_inst = sys_col.get_member(sys_col.members_identities[0])

# Refresh the system collection object
#
# See below for more options on how to refresh resources.
sys_col.refresh()


# Using system actions


# Power the system ON
sys_inst.reset_system(sushy.RESET_ON)

# Get a list of allowed reset values
print(sys_inst.get_allowed_reset_system_values())

# Refresh the system object (with all its sub-resources)
sys_inst.refresh()

# Alternatively, you can only refresh the resource if it is stale by passing
# force=False:
sys_inst.refresh(force=False)

# A resource can be marked stale by calling invalidate. Note that its
# subresources won't be marked as stale, and thus they won't be refreshed by
# a call to refresh(force=False)
sys_inst.invalidate()

# Get the current power state
print(sys_inst.power_state)

# Set the next boot device to boot once from PXE in UEFI mode
sys_inst.set_system_boot_source(sushy.BOOT_SOURCE_TARGET_PXE,
                                enabled=sushy.BOOT_SOURCE_ENABLED_ONCE,
                                mode=sushy.BOOT_SOURCE_MODE_UEFI)

# Get the current boot source information
print(sys_inst.boot)

# Get a list of allowed boot source target values
print(sys_inst.get_allowed_system_boot_source_values())

# Get the memory summary
print(sys_inst.memory_summary)

# Get the processor summary
print(sys_inst.processors.summary)

Creating and using a sushy manager object¶

import logging

import sushy

# Enable logging at DEBUG level
LOG = logging.getLogger('sushy')
LOG.setLevel(logging.DEBUG)
LOG.addHandler(logging.StreamHandler())

s = sushy.Sushy('http://localhost:8000/redfish/v1',
                username='foo', password='bar')

# Instantiate a manager object
mgr_inst = s.get_manager('BMC')

# Get the manager name & description
print(mgr_inst.name)
print(mgr_inst.description)


# Using manager collections


# Instantiate a ManagerCollection object
mgr_col = s.get_manager_collection()

# Print the ID of the managers available in the collection
print(mgr_col.members_identities)

# Get a list of manager objects available in the collection
mgr_insts = mgr_col.get_members()

# Instantiate a manager object, same as getting it directly
# from the s.get_manager()
mgr_inst = mgr_col.get_member(mgr_col.members_identities[0])

# Refresh the manager collection object
mgr_col.invalidate()
mgr_col.refresh()


# Using manager actions


# Get supported graphical console types
print(mgr_inst.get_supported_graphical_console_types())

# Get supported serial console types
print(mgr_inst.get_supported_serial_console_types())

# Get supported command shell types
print(mgr_inst.get_supported_command_shell_types())

# Get a list of allowed manager reset values
print(mgr_inst.get_allowed_reset_manager_values())

# Reset the manager
mgr_inst.reset_manager(sushy.RESET_MANAGER_FORCE_RESTART)

# Refresh the manager object (with all its sub-resources)
mgr_inst.refresh(force=True)


# Using Virtual Media

# Instantiate a VirtualMediaCollection object
virtmedia_col = mgr_inst.virtual_media

# Print the ID of the VirtualMedia available in the collection
print(virtmedia_col.members_identities)

# Get a list of VirtualMedia objects available in the collection
virtmedia_insts = virtmedia_col.get_members()

# Instantiate a VirtualMedia object
virtmedia_inst = virtmedia_col.get_member(
    virtmedia_col.members_identities[0])


# Print out some of the VirtualMedia properties
print(virtmedia_inst.name,
      virtmedia_inst.media_types)

# Insert virtual media (invalidates virtmedia_inst contents)
virtmedia_inst.insert_media('https://www.dmtf.org/freeImages/Sardine.img')

# Refresh the resource to load actual contents
virtmedia_inst.refresh()

# Print out some of the VirtualMedia properties
print(virtmedia_inst.image,
      virtmedia_inst.image_path,
      virtmedia_inst.inserted,
      virtmedia_inst.write_protected)

# ... Boot the system off the virtual media...

# Eject virtual media (invalidates virtmedia_inst contents)
virtmedia_inst.eject_media()

Creating and using a sushy client with Sessions¶

import logging

import sushy

# Enable logging at DEBUG level
LOG = logging.getLogger('sushy')
LOG.setLevel(logging.DEBUG)
LOG.addHandler(logging.StreamHandler())

s = sushy.Sushy('http://localhost:8000/redfish/v1',
                username='foo', password='bar')

# Get the ComputerSystem object (if there is only one), otherwise
# the identity must be provided as a path to the system.
system = s.get_system()

# A session is created automatically for you.
# Print the boot field in the ComputerSystem.
print(system.boot)

# Upon session timeout, Sushy recreates the session based upon
# provided credentials. If this fails, an exception is raised.

# Explicitly request a session_key and session_uri.
# This is not stored, but may be useful.
session_key, session_uri = s.create_session(username='foo',
                                            password='bar')

# Retrieve the session
session = s.get_session(session_uri)

# Delete the session
session.delete()

If you do not have any real baremetal machine that supports the Redfish protocol you can look at the Contributing to Sushy page to learn how to run a Redfish emulator.
