Aliyun Linux images

Aliyun Linux is a Linux public image independently developed by Alibaba Cloud. The following table describes the available versions of Aliyun Linux.
Operating system Version Description
Aliyun Linux 2 Aliyun Linux 2.1903 64-bit

A next-generation OS that supports more Alibaba Cloud instance types (including ECS Bare Metal Instances) than the previous Aliyun Linux image. Aliyun Linux 2 is also equipped with Alibaba Cloud command line tools and other software packages by default.
