deb-s3

deb-s3 is a simple utility to make creating and managing APT repositories on S3.

Most existing existing guides on using S3 to host an APT repository have you using something like reprepro to generate the repository file structure, and then s3cmd to sync the files to S3.

The annoying thing about this process is it requires you to maintain a local copy of the file tree for regenerating and syncing the next time. Personally, my process is to use one-off virtual machines with Vagrant, script out the build process, and then would prefer to just upload the final .deb from my Mac.

With deb-s3, there is no need for this. deb-s3 features:

• Downloads the existing package manifest and parses it.
• Updates it with the new package, replacing the existing entry if already there or adding a new one if not.
• Uploads the package itself, the Packages manifest, and the Packages.gz manifest. It will skip the uploading if the package is already there.
• Updates the Release file with the new hashes and file sizes.

Getting Started

You can simply install it from rubygems:

$ gem install deb-s3

Or to run the code directly, just check out the repo and run Bundler to ensure all dependencies are installed:

$ git clone https://github.com/krobertson/deb-s3.git
$ cd deb-s3
$ bundle install

Now to upload a package, simply use:

$ deb-s3 upload --bucket my-bucket my-deb-package-1.0.0_amd64.deb
>> Examining package file my-deb-package-1.0.0_amd64.deb
>> Retrieving existing package manifest
>> Uploading package and new manifests to S3
   -- Transferring pool/m/my/my-deb-package-1.0.0_amd64.deb
   -- Transferring dists/stable/main/binary-amd64/Packages
   -- Transferring dists/stable/main/binary-amd64/Packages.gz
   -- Transferring dists/stable/Release
>> Update complete.

Usage:
  deb-s3 upload FILES

Options:
  -a, [--arch=ARCH]                     # The architecture of the package in the APT repository.
      [--sign=SIGN]                     # Sign the Release file. Use --sign with your key ID to use a specific key.
  -p, [--preserve-versions]             # Whether to preserve other versions of a package in the repository when uploading one.
  -b, [--bucket=BUCKET]                 # The name of the S3 bucket to upload to.
  -c, [--codename=CODENAME]             # The codename of the APT repository.
                                        # Default: stable
  -m, [--component=COMPONENT]           # The component of the APT repository.
                                        # Default: main
      [--access-key-id=ACCESS_KEY]      # The access key for connecting to S3.
      [--secret-access-key=SECRET_KEY]  # The secret key for connecting to S3.
  -v, [--visibility=VISIBILITY]         # The access policy for the uploaded files. Can be public, private, or authenticated.
                                        # Default: public

Uploads the given files to a S3 bucket as an APT repository.

You can also delete packages from the APT repository. Please keep in mind that this does NOT delete the .deb file itself, it only removes it from the list of packages in the specified component, codename and architecture.

Now to delete the package:

$ deb-s3 delete --arch amd64 --bucket my-bucket --versions 1.0.0 my-deb-package
>> Retrieving existing manifests
   -- Deleting my-deb-package version 1.0.0
>> Uploading new manifests to S3
   -- Transferring dists/stable/main/binary-amd64/Packages
   -- Transferring dists/stable/main/binary-amd64/Packages.gz
   -- Transferring dists/stable/Release
>> Update complete.

You can also verify an existing APT repository on S3 using the verify command:

deb-s3 verify -b my-bucket
>> Retrieving existing manifests
>> Checking for missing packages in: stable/main i386
>> Checking for missing packages in: stable/main amd64
>> Checking for missing packages in: stable/main all

Usage:
  deb-s3 verify

Options:
  -f, [--fix-manifests]                 # Whether to fix problems in manifests when verifying.
      [--sign=SIGN]                     # Sign the Release file. Use --sign with your key ID to use a specific key.
  -b, [--bucket=BUCKET]                 # The name of the S3 bucket to upload to.
  -c, [--codename=CODENAME]             # The codename of the APT repository.
                                        # Default: stable
  -m, [--component=COMPONENT]           # The component of the APT repository.
                                        # Default: main
      [--access-key-id=ACCESS_KEY]      # The access key for connecting to S3.
      [--secret-access-key=SECRET_KEY]  # The secret key for connecting to S3.
  -v, [--visibility=VISIBILITY]         # The access policy for the uploaded files. Can be public, private, or authenticated.
                                        # Default: public

Verifies that the files in the package manifests exist

TODO

This is still experimental. There are several things to be done.
