Usage scenarios

Creating a cloud host mirror from an external file
Using the existing original mirror files, private or public mirrors (currently supporting ISO, QCOW2 and RAW formats) are produced, which is convenient for service migration and batch deployment of services.
Batch deployment of software environments
The information such as operating system, partition and software of the deployed cloud host is packaged to make a private mirror, and then the private mirror is used to create a batch of cloud hosts, and the cloud hosts will have the same environment information, so as to achieve the purpose of batch deployment.
Deploying a specific software environment
The use of customized mirror can help enterprises quickly build a specific software environment, avoiding the time-consuming work such as configuring the environment and installing software by themselves.
