Flaky Test - TestDocker (a packaging test) fails validating exported images

Flaky Test

• Test Name: TestDocker
• Link:

  beats/dev-tools/packaging/package_test.go

  Lines 748 to 752 in 3198a68

  	case strings.HasSuffix(header.Name, ".json") && header.Name != "manifest.json":
  	info, err = readDockerInfo(tarReader)
  	if err != nil {
  	return nil, nil, err
  	}

• Branch: main
• Artifact Link: If available, attach the generated zip artifact associated with the stack trace for this failure.
• Notes: The docker engine version being used on CI has changed to export images in the OCI Image Layout. Our test is expecting to find a JSON file in the root of the image, but that is now moved into a blobs/sha256/<layer> where the path is determined by reading jq '.[].Config manifest.json'.

Thanks, we need to update this check to handle both formats. As we have just learned, Beats itself isn't in control of when the format can change.

Potential fix: #37727
