OCI blob

Tag 1: the server asks the client for a blob of an image the client holds, by digest, when its registry lacks it; the client answers with the bytes in zero or more channel responses; bytes that are not those the digest names fail the run.

The server opens this channel when it obtains the image of the request from the client and its registry does not hold a blob that the pull requires: a config or a layer.

• When. Between the request and the deploy.
• The request. The tag byte 1 followed by the digest as JSON. Request states its form.
• The response. The bytes of the blob in zero or more channel responses and the channel response finish. Response states the sequence.
• The image. The server runs only the image the digest names. A blob that ends short, and bytes that are not those the digest names, are the run’s error. How the server holds, verifies or streams the bytes, and how it answers a range the runtime asks for, are not prescribed.
