Class GetDownloadUrlForLayerCommandProtected

Retrieves the pre-signed Amazon S3 download URL corresponding to an image layer. You can only get URLs for image layers that are referenced in an image.

When an image is pulled, the GetDownloadUrlForLayer API is called once per image layer that is not already cached.

This operation is used by the Amazon ECR proxy and is not generally used by customers for pulling and pushing images. In most cases, you should use the docker CLI to pull, tag, and push images.

Example

Use a bare-bones client and the command you need to make an API call.

import { ECRClient, GetDownloadUrlForLayerCommand } from "@aws-sdk/client-ecr"; // ES Modules import
// const { ECRClient, GetDownloadUrlForLayerCommand } = require("@aws-sdk/client-ecr"); // CommonJS import
const client = new ECRClient(config);
const command = new GetDownloadUrlForLayerCommand(input);
const response = await client.send(command);
