Re: About salt-ami-cloud-builder - build AMI images using salt

Excellent! It would be great to see it eventually end up in Debian.

Congratulations. It would be awesome if someone could package this for Debian.

Thanks for the kind word.

We are indeed planning to package this for debian (we package most of the open source software we write at Logilab). We'll start by publishing it in our debian repos : http://www.logilab.org/893 and if people are using it, we'll see if can go into the distribution.

The ticket for the packaging : http://www.logilab.org/ticket/150456

At Logilab we are big fans of SaltStack, we use it quite extensively to
centralize, configure and automate deployments.

We've talked on our blog about how to build a debian AMI "by hand"
http://www.logilab.org/blogentry/115219 and we wanted to automate this
fully. Hence the salt way seemed to be the obvious way to go.

So we wrote salt-ami-cloud-builder. It is mainly glue between existing
pieces of software that we use and like. If you already have some
definition of a type of host that you provision using salt-stack,
salt-ami-cloud-builder should be able to generate the corresponding AMI.


Building a Debian based OpenStack private cloud using salt made us
realize that we needed a way to generate various flavours of AMIs for
the following reasons:

*  Some of our openstack users need "preconfigured" AMIs (for example a
Debian system with Postgres 9.1 and the appropriate Python bindings)
without doing the modifications by hand or waiting for an automated
script to do the job at AMI boot time.

*  Some cloud use cases require that you boot many (hundreds for
instance) machines with the same configuration. While tools like salt
automate the job, waiting while the same download and install takes
place hundreds of times is a waste of resources. If the modifications
have already been integrated into a specialized ami, you save a lot of
computing time. And especially in the amazon (or other pay-per-use cloud
infrastructures), these resources are not free.

* Sometimes one needs to repeat a computation on an instance with the
very same packages and input files, possibly years after the first run.
Freezing packages and files in one preconfigured AMI helps this a lot.
When relying only on a salt configuration the installed packages may not
be (exactly) the same from one run to the other.
