The ack-arena add-on further simplifies open-source Arena installation and enables one-click Arena deployment from the console. This topic describes the add-on, usage notes, and release history.Arena in ACK clusters through the console without manual Kubernetes setup.

What is Arena

Arena is a lightweight Kubernetes client for ML workloads. It covers the full lifecycle — data preparation, model development, training, and prediction — so data scientists can focus on models, not cluster management.

Arena integrates with Alibaba Cloud services, supports GPU sharing and Cloud Paralleled File System (CPFS), and runs optimized deep learning frameworks to maximize heterogeneous computing resource usage.

Why use ack-arena

ack-arena simplifies Arena installation. Manual Arena installation requires configuring Kubernetes resources, namespaces, RBAC, and operators. ack-arena automates this through the ACK console, reducing setup to a few clicks.

ack-arena stays integrated with ACK. ack-arena deploys Arena as a managed component, keeping it aligned with ACK service updates and GPU resource management.

Usage notes
