Repository DockerDaemon - Images stored in a Docker Daemon

Synopsis

type: DockerDaemon/v1

Description

This repository type provides a mapping of the image repository behind a docker daemon to the OCI registry access API.

This is only possible with a set of limitation:

• It is only possible to store and access flat images
• There is no access by digests, only by tags.
• The docker image id can be used as pseudo digest (without algorithm)

Specification Versions

Version v1

The type specific specification fields are:

• dockerHost string

  Address of the docker daemon to use.
