I do often spin up Alibaba Cloud ECS instance from time to time to evaluate new features or to run some experimental project.

Usually, different project would have different set of requirements, such as operating system, software and configuration.

In this tutorial, I’ll walk through how to re-image an Alibaba Cloud ECS instance.

On the System Disk section, you can change the size of the disk according to suite your requirements.

On the Security section, you can Set Password or create an SSH key pair as the authentication method.
