ack-arena - Container Service for Kubernetes - Alibaba Cloud Documentation Center

The ack-arena component is a collection of lifecycle management tools for AI jobs provided by the cloud-native AI suite. The component abstracts and standardizes key components throughout AI production, which reduces the complexity of underlying resource and environment management and simplifies the procedure for submitting and running AI jobs. This topic describes the basic information, usage notes, and release notes of ack-arena.

Introduction

The cloud-native AI suite provides an abstraction of data preparation and management, model development, model training, model evaluation, model inference services, and online O&M. Arena is a command-line tool that can help you manage these key components in AI DevOps. Arena simplifies the management of underlying resources and environments, job scheduling, and GPU allocation and monitoring. Arena is compatible with mainstream AI frameworks and tools, including TensorFlow, PyTorch, Horovod, Spark, JupyterLab, TF-Serving, and Triton. Arena also provides SDKs for Golang, Java, and Python.

ack-arena is optimized to simplify operations in open source Arena. You can install ack-arena in the Container Service for Kubernetes (ACK) console with a few clicks.

Usage notes

The ack-arena component can be installed only in ACK Pro clusters, ACK Serverless Pro clusters, and ACK Edge Pro clusters. The Kubernetes versions of the clusters must be 1.18 or later. For more information about how to install and use the ack-arena component, see Configure the Arena client.
