Spotinst SDK Python

The official Spotinst SDK for the Python programming language.

Version 2

The new Spotinst Python SDK comes with a few breaking changes but do not fear, here we will explain all you need to know to make sure you can go right back in buisness in no time.

• There is no longer the SpotinstClient() class which was used to validate your credentials and make requests all in one
• Now there is the SpotinstSession() class which is used to validate credentials. Configure Session Docs
• From the session object you can create client objects which correlate to specific Spotinst Services and are used to make requests. Setup Clients Docs
• Some methods required you to pass in a Model object

Here is a basic example of how to create an Ocean cluster using the Ocean Client and the Ocean Models

from spotinst_sdk2 import SpotinstSession
from spotinst_sdk2.models.ocean.aws import *

session = SpotinstSession()
client = session.client("ocean_aws")

################ Compute ################
launch_specification = LaunchSpecifications(security_group_ids=["sg-12345"],
 image_id="ami-12345", key_pair="Noam-key")

instance_types = InstanceTypes(whitelist=["c4.8xlarge"])

compute = Compute(instance_types=instance_types, 
  subnet_ids=["subnet-1234"], launch_specification=launch_specification)

################ Strategy ################

strategy = Strategy(utilize_reserved_instances=False, fallback_to_od=True, spot_percentage=100)

################ Capacity ################

capacity = Capacity(minimum=0, maximum=0, target=0)

################# Ocean #################

ocean = Ocean(name="Ocean SDK Test", controller_cluster_id="ocean.k8s", 
  region="us-west-2", capacity=capacity, strategy=strategy, compute=compute)

client.create_ocean_cluster(ocean=ocean)

In the SDK Client documentation you can view what methods are supported by each client.
For information on what models are supported checkout the SDK Model documentation.
More examples can be found in the SDK Examples Documentation.

Installation

pip install --upgrade spotinst-sdk2

Authentication

The mechanism in which the SDK looks for credentials is to search through a list of possible locations and stop as soon as it finds credentials. The order in which the SDK searches for credentials is:

1. Passing credentials as parameters when creating a SpotinstSession object:

session = SpotinstSession(auth_token='foo', account_id='bar')

2. Environment variables:

export SPOTINST_TOKEN=foo
export SPOTINST_ACCOUNT=bar

3. Shared credentials file:

• The shared credentials file has a default location of ~/.spotinst/credentials. This file is an INI formatted file with section names corresponding to profiles. With each section, two configuration variables can be specified: token, account. These are the only supported values in the shared credential file.

• Below is a minimal example of the shared credentials file:

[default]
token   = foo
account = bar

• The shared credentials file also supports the concept of profiles. Profiles represent logical groups of configuration. The shared credential file can have multiple profiles:

[default]
token   = foo
account = bar

[dev]
token   = foo2
account = bar2

[prod]
token   = foo3
account = bar3

• You can configure your Spot credentials using the spotctl configure command. For more information, see the spotctl Getting Started.

• To maintain compatibility with previous SDK versions, the file can also be in YAML format:

default:
  token: foo
  account: bar
  
dev:
  token: foo2
  account: bar2
  
prod:
  token: foo3
  account: bar3

• You can change the location of the credentials file and the profile used by setting the SPOTINST_SHARED_CREDENTIALS_FILE and/or SPOTINST_PROFILE environment variables:

export SPOTINST_SHARED_CREDENTIALS_FILE=/path/to/credentials_file
export SPOTINST_PROFILE=dev

• Passing the credentials file location and the profile used as parameters when creating a SpotinstSession object:

session = SpotinstSession(credentials_file='/path/to/credentials_file', profile='dev')

Setup Clients

After a session is created you can use the session object to create clients. Clients are used to make request to the different services that Spotinsts has to offer. To create a client simply use the method client from the session object and pass in the string of the client you wish to create. Here is an example:

session = SpotinstSession()

eg_client = session.client("elastigroup_aws")
ocean_client = session.client("ocean")

Take note you can create more than one client with the session. The currently supported clients are

Client Options

• session.client("admin")
• session.client("setup_aws")
• session.client("setup_azure")
• session.client("setup_gcp")
• session.client("elastigroup_aws")
• session.client("elastigroup_azure_v3")
• session.client("elastigroup_gcp")
• session.client("mcs")
• session.client("mrScaler_aws")
• session.client("ocean_aws")
• session.client("ocean_azure")
• session.client("ocean_gcp")
• session.client("ocean_ecs")
• session.client("ocean_rightsizing")
• session.client("subscription")
• session.client("managed_instance_aws")
• session.client("stateful_node_azure")
• session.client("functions")

A full list of endpoints and clients can be found in the documentation here.
