Command Line Interface for the YellowDog Platform

Overview

This is a set of Python CLI commands for interacting with the YellowDog Platform, also providing examples of usage of the YellowDog Python SDK.

The CLI is one command, yd. Most of what it does names the object acted on, then what to do to it — yd workrequirement submit, yd instance terminate — and yd <noun> --help lists a noun's verbs; yd help lists everything. The commands support:

• Work Requirements — submitting, cancelling, holding, starting, finishing and reprioritising them, and comparing them against Worker Pools, with yd workrequirement (short form yd wr)
• Task Groups and Tasks — reprioritising Task Groups and comparing them against Worker Pools with yd taskgroup (yd tg), and aborting running Tasks with yd task
• Worker Pools — provisioning, resizing and shutting them down, and refreshing or regenerating Configured Worker Pools' tokens, with yd workerpool (yd wp)
• Compute Requirements — instantiating, resizing, stopping, starting, reprovisioning and terminating them with yd computerequirement (yd cr)
• Instances and Nodes — stopping, starting, restarting, deprovisioning and terminating individual Instances with yd instance, and Worker Pool Nodes' Instances with yd node, which also shuts Nodes down and submits Node Actions to them
• Resources — creating, updating and removing Compute Source Templates, Compute Requirement Templates, Keyrings, Credentials, Image Families, Namespaces, Allowances, Configured Worker Pools, Attribute Definitions, Namespace Policies, Groups, Applications and Users (update only) with yd resource, from specification files or, for a resource of a few properties, on the command line (yd resource create --type Keyring --set name=team-keys), and showing or removing them by name
• Allowances — boosting them with yd allowance
• Remote data stores — uploading, downloading, listing, deleting and copying files with yd data
• Cloud provider setup (AWS, Azure, GCP) with the yd cloudwizard command
• Cloud regions, instance types and prices, as the YellowDog Platform knows them, with yd cloudinfo
• Inspecting — listing YellowDog items with yd list, filtered by name, status or provider, or within one Work Requirement, Task Group, Compute Requirement, Worker Pool or Node (yd task list --within <wr>), the largest listings stopping at 1000 items unless --limit says otherwise, showing any entity's details by its YellowDog ID with yd show, following event streams with yd follow, and waiting for Work Requirements, Worker Pools or Compute Requirements to finish with yd wait; every noun also has list and show verbs for its own objects
• Showing the details of the current Application with the yd application command
• Diagnosing the configuration, credentials and connectivity with the yd doctor command
• Reporting the processed values of variable substitutions with the yd variables command
• Completing commands, verbs, options and their values on Tab, in bash, zsh, fish and PowerShell, with the yd completion command

Utility commands are also provided: yd completion, yd doctor, yd format-json, yd help, yd jsonnet2json, yd schema, and yd version. For a full list of commands run yd help.

The remote data store commands — the yd data verbs upload, download, delete, ls and copy — use rclone, and do not require YellowDog credentials. An rclone binary already on your PATH is used in preference and is never modified; otherwise one is downloaded to a per-user cache directory the first time it's needed.

Installation

Python 3.10 or later is required.

pipx (recommended) — installs into an isolated environment and puts the commands on your PATH automatically:

pipx install yellowdog-cli

uv:

uv tool install yellowdog-cli

pip + virtual environment:

python3 -m venv yd-env
source yd-env/bin/activate   # macOS / Linux; on Windows: yd-env\Scripts\activate
pip install -U yellowdog-cli

Optional Extras

Four optional extras are available:

List the ones you need in square brackets at installation time, e.g. to install all four:

pipx install "yellowdog-cli[jsonnet,commander,cloudwizard,mcp]"    # pipx
uv tool install "yellowdog-cli[jsonnet,commander,cloudwizard,mcp]" # uv
pip install -U "yellowdog-cli[jsonnet,commander,cloudwizard,mcp]"  # pip

An extra can also be added to an existing pipx installation without reinstalling it, e.g. pipx inject yellowdog-cli jsonnet.

Commander GUI

yd commander is an optional cross-platform desktop GUI for driving the CLI, installed via the commander extra above:

pip install -U "yellowdog-cli[commander]"
yd commander

It works by running yd commands on your behalf and displaying their output. See the Commander documentation for details.

MCP Server

yd mcp is an optional MCP server exposing the yd commands as tools for an agent, installed via the mcp extra above:

pip install -U "yellowdog-cli[mcp]"
yd mcp config.toml

It runs yd commands on an agent's behalf, with --json, and returns their results. See the MCP server documentation for details.
