Container image repository

Images are served via HTTP. The directory structure, relative to the repository's URL, is:

.
└── <schema version>/
    ├── <vendor>/
    │   ├── default -> <variant>
    │   └── <variant>/
    │       └── <arch>/
    │           └── <distribution>/
    │               ├── <tag> -> <version>
    │               └── <version>/
    │                   └── image-{archive,stream}.tar
    ├── default -> <vendor>
    └── INDEX.json

default entries are symlinks to the default vendor and variant directories, which the client can use when he has no particular requirements.

tag is a symlink to specific distribution version, common tags include:

• stable
• unstable
• latest
• testing
