Publish Repositories, Snapshots, Mirrors

Publish snapshot or local repo as Debian repository to be used as APT source on Debian based systems.

The published repository is signed with the user's GnuPG key.

Repositories can be published to local directories, Amazon S3 buckets, Azure or Swift Storage.

GPG Keys

GPG key is required to sign any published repository. The key pari should be generated before publishing.

Publiс part of the key should be exported from your keyring using gpg --export --armor and imported on the system which uses a published repository.

Parameters

Publish APIs use following convention to identify published repositories: /api/publish/:prefix/:distribution. :distribution is distribution name, while :prefix is [<storage>:]<prefix> (storage is optional, it defaults to empty string), if publishing prefix contains slashes /, they should be replaced with underscores (_) and underscores should be replaced with double underscore (__). To specify root :prefix, use :., as . is ambigious in URLs.
