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
- This operation is supported only when the system disk is an EVS disk.
- 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.
- 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 before using it to creating a private image to prevent data leak.
- Delete residual files from the OS. For details, see "Deleting Files" in Bare Metal Server Private Image Creation Guide.
- During the image creation process, do not change the BMS status. Otherwise, the image will fail to be created.
Procedure
- Log in to the management console.
- Under Computing, click Bare Metal Server.
The BMS console is displayed.
- 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.
- 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.
- Enter the image name, set a tag, and enter description as needed.
Click Create Now.
- On the displayed Details page, confirm the configuration and click Submit.
- 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.
