    Elastic Compute Service:CreateImageComponent

    Last Updated:Sep 29, 2024

    Creates an image component. Image components are used to store the image template commands that are commonly used to create images.

    Operation description

    Take note of the following items:

    • Only custom image components can be created.
    • The images must run Linux operating systems. This indicates that you must set SystemType to Linux.
    • You must set the image component type to image build component by setting the ComponentType parameter to Build.
    • You can use Dockerfile to edit the content of image components, and then pass the edited content into the Content parameter. The content size must not be greater than 16 KB. FROM commands cannot be used in image components. An image component supports up to 127 commands. For information about supported commands, see Description of commands supported by Image Builder.

    You can use image components to create image templates in the Elastic Compute Service (ECS) console, but cannot call API operations to use image components to create image templates. For more information, see Overview of Image Builder.

    Debugging

    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
