Alibaba ACK Distro is a Kubernetes distribution based on Alibaba Container Service for Kubernetes to support production ready Kubernetes deployment for heterogeneous IaaS environment. Users can get complete content and community support for free through Alibaba Cloud. Its components have been verified and security checked by Alibaba Cloud Container Service for Kubernetes (ACK) and Alibaba Group's core business scenarios in large-scale production environment, with industry-leading security and reliability.

As a complete Kubernetes distribution, ACK Distro can be delivered to on-premise environment simply and quickly through sealer, an open-source application packaging delivery tool of Alibaba, helping users to manage their clusters more simply and flexibly. The components support both x86 and ARM hardware architectures, and include a high-performance network plugin hybridnet, which ensures that ACK Distro can run smoothly over a diverse infrastructure. At the same time, ACK Distro can be registered on the ACK service to achieve consistent resource management, policy compliance and traffic control, so that users can obtain the same user experience as the online ACK cluster.

The main difference between ACK Distro and ACK clusters is that ACK clusters are deployed on and managed by Alibaba Cloud, while ACK Distro clusters are managed by yourself and can be deployed on on-premise environments, other cloud service providers or even your own PCs.

ACK Distro, as a downstream of ACK, will keep up-to-date with ACK's release. ACK Distro will release the same version within one month after ACK releases a new version, and ACK keeps updating the minor version of Kubernetes once every six months in principle. Please refer to the Appendix for the specific release strategy.

• Support multiple deployment topologies including single-node, three-node, etcd/apiserver separation (under planning)
• Support preflight and post-check for cluster
• Support deployment on various IaaS such as ECS, VMware, VirtualBox, ZStack, OpenStack and bare metal
• Support deployment on various OS such as Red Hat, Debian, Open Anolis, Kylin, Windows (under planning)
• Support deployment on various architectures such as x86, arm64 (under planning), etc.
