Easy APT repo in S3

When running a number of Ubuntu or Debian servers, it can be extremely useful to have a custom APT repo for uploading your own packages, or third party packages that lack their own good repositories to subscribe to.

I recently found a nice Ruby utility called deb-s3 which allows easy uploading of dpkg files into an S3-hosted APT repository. It’s much easier than messing around with tools like reprepro and having to s3 cp or sync files up from a local disk into S3.

One main warning: This will create a *public* repo by default since it works out-of-the-box with the stock OS and (in my case) all the packages I’m serving are public open source programs that don’t need to be secured. If you want a *private* repo, you will need to use apt-transport-s3 to support authenticating with S3 to download files and configure deb-s3 for private upload.

Install like any other Ruby Gem:

gem install deb-s3

Adding packages is easy. First make sure your aws-cli is working OK and an S3 bucket has been created, then upload with:

deb-s3 upload \
--bucket example \
--codename codename \
--preserve-versions \
mypackage.deb

You can then add the repo to a Ubuntu or Debian server with:

# We trust HTTPS rather than GPG for this repo - but you can config
# GPG signing if you prefer.
cat > /etc/apt/sources.list.d/myrepo.list << EOF
deb [trusted=yes] https://example.s3.amazonaws.com codename main
EOF

# and ensure you update the package info on the server
apt-get update

Alternatively, here’s an example of how to add the repo with Puppet:

apt::source { 'myrepo':
 comment        => 'This is our own APT repo',
 location       => 'https://example.s3.amazonaws.com',
 release        => $::os["distro"]["codename"],
 repos          => 'main',
 allow_unsigned => true, # We don't GPG sign, HTTPS only
 notify_update  => true, # triggers apt-get update
}

    If you fancy something more advanced, https://www.aptly.info/ looks like an interesting option with features including repo mirroring and snapshotting.
