Using Sushy

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)

Creating and using a sushy session service 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 SessionService object
sess_serv = s.get_session_service()

# Get SessionCollection
sess_col = sess_serv.sessions

# Print the ID of the sessions available in the collection
print(sess_col.members_identities)

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

# Instantiate a session object, same as getting it directly
sess_inst = sess_col.get_member(sess_col.members_identities[0])
# Getting it directly
sess_inst = s.get_session(sess_col.members_identities[0])

# Delete the session
sess_inst.delete()

# Create a new session
session_key, session_id = sess_serv.create_session(
  username='foo', password='bar')

# Delete a session
sess_serv.close_session(sess_col.members_identities[0])

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.
