Union Flyte Plugin

Proprietary extensions and features for Flyte, providing Union-specific functionality.

Installation

uv pip install flyteplugins-union

For development:

uv pip install -e .

Flyte compatibility

flyteplugins-union builds on flyte SDK internals that can change between flyte minor releases, so each release pins flyte to a single minor line. Install a flyteplugins-union release built for your flyte minor:

flyteplugins-union	Requires flyte
0.11.0+	`>=2.6.7,<2.9.0`
0.8.2 – 0.10.9	`>=2.6.7,<2.7.0`
0.8.0 – 0.8.1	`>=2.6.3,<2.7.0`
0.7.2	`>=2.5.20,<2.7.0`
0.5.0 – 0.7.1	`>=2.5.7,<2.6.0`
0.4.3	`>=2.5.0,<2.6.0`
0.4.0 – 0.4.2	`>=2.3.0,<2.5.0`
0.3.0	`>=2.1.0,<2.5.0`

See COMPATIBILITY.md for the rationale and how the pin tracks new flyte releases.

Features

API Key Management

Create and manage API keys for headless authentication with Union.

Create an API Key

flyte create api-key admin --name my-api-key

This will create OAuth application credentials and output an API key that can be used for headless authentication.

Example output:

Client ID: serverless-1-myorg-my-api-key
The following API key will only be shown once. Be sure to keep it safe!
Configure your headless CLI by setting the following environment variable:

export FLYTE_API_KEY="<base64-encoded-credentials>"

Using the API Key

Set the generated API key as an environment variable:

export FLYTE_API_KEY="<your-api-key>"

Then use the Flyte CLI as normal - it will authenticate using the API key instead of prompting for interactive login.

Architecture

The Union SDK is structured as follows:

flyteplugins/union/internal/ - Proprietary protobuf definitions and generated code
flyteplugins/union/cli/ - CLI command plugins that extend the Flyte CLI
flyteplugins/union/utils/ - Shared utility functions
flyteplugins/union/remote/ - Union-specific remote objects

Plugin System

The SDK registers CLI plugins via entry points in pyproject.toml:

[project.entry-points."flyte.plugins.cli.commands"]
"create.api-key" = "flyteplugins.union.cli.api_key:create_api_key"
"delete.api-key" = "flyteplugins.union.cli.api_key:delete_api_key"
"get.api-key" = "flyteplugins.union.cli.api_key:get_api_key"

This makes Union commands available seamlessly through the Flyte CLI.

Dependencies

flyte - The Flyte SDK v2 (pinned to a single minor; see Flyte compatibility)
rich-click>=1.8.0 - For CLI formatting

Development

To add a new CLI plugin:

Create a new file in src/flyteplugins/union/cli/
Define your click commands
Register the entry point in pyproject.toml
Shared resources (protobufs, utilities) are available in flyteplugins.union.internal.* and flyteplugins.union.utils.*

Iterating

Commands to rebuild and reinstall this plugin (into the flyte-sdk venv presumably). From this folder:

python -m build --wheel

From your flyte-sdk venv:

uv pip install --prerelease=allow --force-reinstall --no-deps --no-index --find-links /Users/ytong/go/src/github.com/unionai/flyteplugins-union/dist flyteplugins-union
