This Java library turns your binary storage
(files, S3 objects, anything) into a Debian repository.
You may add it to your binary storage and it will become
a fully-functionable Debian repository, which
apt
will perfectly understand.
Debian repository has the following structure:
(repository root)
|
+-dists
|
|-my_repo
| |-main
| | |-binary-*
| | +-source
| |-contrib
| | |-binary-*
| | +-source
| +-non-free
| |-binary-*
| +-source
|
|-testing
| ...
|
+-unstable
| ...
|
main contains free package, non-free - non-free ones and contrib contains free packages which
depend on non-free ones. testing and unstable have the same structure as main or testing.
* in binary-* stands for the architecture, currently Debian supports
more than 20 of them. Each binary-* directory contains a Packages.gz index file. Index files contain
paths to the individual packages, so packages can be located anywhere in the repository.
File /dists/my-repo/Release (or gpg-signed /dists/my-repo/InRelease file) contains
general information about the repository and list of the checksums and paths to the Packages indexes.
Release files contain information about distribution
and checksums for the indexes, they are located in the repository root /dists/my-repo/Release.
Here is the example with minimal fields set:
Codename: artipie #Repository name
Architectures: amd64 #Space separated supported architectures set
Components: main #Repository components set
Date: Sat, 05 Dec 2020 10:35:57 UTC #Creation date
SHA256: #checksums for Packages indexes
eb8cb7a51d9fe47bde0a32a310b93c01dba531c6f8d14362552f65fcc4277af8 1351 main/binary-amd64/Packages.gz
c1cfc96b4ca50645c57e10b65fcc89fd1b2b79eb495c9fa035613af7ff97dbff 2564 main/binary-amd64/Packages
The most important fields here are Architectures (list of the architectures
this repository supports separated by space) and Components (a whitespace separated list of
components or areas, in the layout above components are main, contrib and non-free) as they
define repository structure.
SHA256 field contains list of the repository Packages indexes files along with their sha-256
checksum, size and filename relative to the directory of the Release file. Checksums data have
to be provided for uncompressed files as well even if they are not present in the repository.
Packages index files are called Binary Packages Indices
and contains information about packages in paragraphs, each paragraph has the format defined by
Debian Policy
and several other fields such as Filename, Size and checksums, here is an example of one paragraph
(information about one package):
Package: aglfn
Version: 1.7-3
Architecture: all
Maintainer: Debian Fonts Task Force <[email protected]>
Installed-Size: 138
Filename: main/aglfn_1.7-3_all.deb
Size: 29238
MD5sum: cee972bb5e9f9151239e146743a40c9c
SHA1: d404261883ae7bd5a3e35abca99b1256ae070ed5
SHA256: 421a5c6432cb7f9c398aa5c89676884e421ad0fde6bf13d0cadee178bf0daf7c

Description: Adobe Glyph List For New Fonts
AGL (Adobe Glyph List) maps glyph names to Unicode values ...
Debian repository can be added to the apt-get sources list by editing /etc/apt/sources.list file,
here is the file entry format:
deb [trusted=yes] http://site.example.com/debian distribution component1 component2 component3
distribution is repository name, my-repo in the example above, components are set of the
repository components apt is allowed to work with, parameter [trusted=yes] allows to work
without gpg-signatures.
