Creating a Private Image from a BMS

Scenarios

You can create a private image from a BMS and copy the system disk data of the BMS to the private image. The system disk contains an OS and pre-installed applications for running services.

Constraints

• Currently, only a BMS that supports quick provisioning (the OS is installed on an EVS disk) can be used to create a private image.
• Data disks of a BMS cannot be exported as images.
• The BMS must be stopped.
• This operation depends on the bms-network-config and Cloud-Init plug-ins in the BMS image.
  

  Do not delete or modify built-in plug-ins of an image, such as Cloud-Init and bms-network-config. Otherwise, basic BMS functions may be unavailable.

  • If the BMS is created using a public image, the image has the bms-network-config and Cloud-Init plug-ins by default.
  • If the BMS is created using a private image, check whether bms-network-config and Cloud-Init are installed by following the instructions in Bare Metal Server Private Image Creation Guide.

Precautions

• Delete sensitive data from the BMS to prevent data leak before using it to creating a private image.
• Delete the configdrive partition.

  If you used a BMS in a special network, a partition of about 64 MB will be generated. If the partition is not deleted before you use the BMS to create a private image, data in this partition will remain in the image.

  

  Run the following command:

  fdisk /dev/sda

  d # Deletion command

  3 # Location of the configdrive partition

  w # Command to save the change

  

  Example: configdrive partition deleted

  

• Delete residual files from the OS. For details, see Deleting Files.
• During the image creation process, do not change the BMS status. Otherwise, the image will fail to be created.

Procedure

1. Log in to the BMS console.
2. Locate the row that contains the target BMS, click More in the Operation column, and select Stop from the drop-down list.

   Only a BMS in stopped state can be used to create a private image.

3. After the BMS status changes to Stopped, click More in the Operation column and select Create Image.

   The page for creating an image is displayed.

4. Enter the image name, select an enterprise project, set a tag, and enter description as needed.

   Click Next.

5. On the displayed Details page, confirm the configuration and click Submit.
6. Return to the image list. If the status of the private image changes to Normal, the private image is created successfully.

Follow-up Operations

If you want to create BMSs using the private image, see Creating a BMS Using a Private Image. On the page for creating BMSs, select the private image you have created.
