Subject Re: [ANNOUNCE] Apache Deltacloud 0.4.1 (incubating)
Date Wed, 12 Oct 2011 11:19:16 GMT
Hi Christian,

thanks for your comments - you're right, the website is pretty
under-updated recently. We've finished a tidying up of the website
content - clearer download/setup instructions, more info for developers
etc but have been holding off on deploying the updated site content
specifically waiting for release 4.0.1. Mainly because the updated site
documents the 'easy' installation of deltacloud using rubygems (i.e. gem
install deltacloud-core) - and this only works because of the updated
.gemfile dependencies in release 4.0.1. (basically, the gemfile outlines
all 'runtime' gems - especially the ones that deltacloud uses to talk to
the cloud providers like aws).

I just checked and we haven't yet pushed the updated
deltacloud-core gem (4.0.1); this should happen in the next few
hours/day. Once that is done I will also deploy the updated site content.

One the new gem is pushed to, you'll be able to get the
latest release by:

  gem install deltacloud-core

For now, you can get the release at the - I take your point
about the mirroring system.

If you have the time/interest, you can use the git mirror to get the
sources+build the latest:

mkdir DeltacloudProject; cd DeltacloudProject
git clone git://
cd ./deltacloud/server
rake package
sudo gem install ./pkg/deltacloud-core-0.4.1.gem

We also have a github page which mirrors the apache repo at if you prefer github.

As I say, the 4.0.1 will be deployed to rubygems very soon - once that
happens 'gem install deltacloud-core' will give you the latest release
and all its dependencies,

all the best, marios
