Cloud-Init is an open-source cloud initialization program, which initializes specified customized configurations, such as the host name, key, and user data, of a newly created BMS.
Currently, all standard images (in Standard_xxx format) support Cloud-Init.
Using Cloud-Init to initialize BMS configurations will influence your BMS and IMS services.
To ensure that BMSs created using private images support customized configurations, you must install Cloud-Init or Cloudbase-Init when creating private images.
After Cloud-Init or Cloudbase-Init is installed in an image, Cloud-Init or Cloudbase-Init automatically configures initial BMS attributes when the BMS is created. For details about how to install Cloud-Init and Cloudbase-Init, see Bare Metal Server Private Image Creation Guide.
