h2o-cloud-discovery

H2O Cloud Discovery Client.

Installation

pip install h2o-cloud-discovery

Usage

Package provides two main functions. Synchronous h2o_discovery.discover() and asynchronous h2o_discovery.discover_async(). Both functions return a discovery object that can be used to obtain the information the H2O Cloud environment, its services and clients.

When used within the H2O AI Cloud environment or locally with the H2O AI Cloud CLI configured, no further configuration is needed.

Both functions accept a environment argument that can be used to specify the H2O Cloud environment for which the discovery should be performed. Alternatively, the H2O_CLOUD_ENVIRONMENT environment variables can be used.

See API documentation for more details.

import h2o_discovery

discovery = h2o_discovery.discover()

# Print the H2O Cloud environment that was discovered.
print(discovery.environment.h2o_cloud_environment)

# Connect to the my service.
my_service_client = my_service.client(address=discovery.services["my-service"].uri)

Examples

Example: Use within a notebook to connect to the H2O AI Drive

# Install required packages.

import sys
!{sys.executable} -m pip install h2o-cloud-discovery h2o-authn[discovery]

# Load discovery for the current environment.

import h2o_discovery
discovery = h2o_discovery.discover()

# Create a token provider using the credentials loaded from the environment.

import h2o_authn.discovery
token_provider = h2o_authn.discovery.create_async(discovery)

# Install the H2O AI Drive client in the version specified by the available
# service.

import sys
!{sys.executable} -m pip install '{discovery.services["drive"].python_client}'

# Connect to the H2O AI Drive and list home objects.

import h2o_drive
home = await h2o_drive.MyHome(
    token=token_provider,
    endpoint_url=discovery.services["drive"].uri,
)
await home.list_objects()
