2. Service Discovery and Puppet
Want to know how to allow Puppet to react to dynamically
changing platforms? In this talk we will take you from the
basics of what service discovery is, all the way to real life
examples of dynamically changing configuration managed
through Puppet.

3. Using Puppet With Kubernetes and
OpenShift
OpenShift is Red Hat's Platform-as-a-Service that allows
developers to quickly develop, host, and scale applications in a
cloud environment. OpenShift is also available in an open source
distribution called OpenShift Origin. OpenShift provides an
integrated set of tools for managing your container-based
applications, everything from deployment to container repositories
to access control and built-in metrics and monitoring services.
Since V3, OpenShift has been built around Kubernetes, the cluster
manager released by Google. Red Hat have been one of the main
contributors to the open source Kubernetes project since its
release. Puppet recently released a module for managing
Kubernetes resources (like Pods, Replication Controllers and
Services) using Puppet. In this briefing, we'll look at how you can
use that module to power your OpenShift-based PaaS.

4. The Challenges with Container
Configuration
Introducing containers into your infrastructure brings new
capabilities, but also new challenges, in particular around
configuration. This talk will take a look under the hood at
some of those operational challenges including: * The
difference between runtime and build-time configuration,
and the importance of relating the two together. *
Configuration drift, immutable mental models and mutable
container file systems. * Who configures the
orchestrators? * Emergent vs. model driven configuration.
In the process we will identify some common problems
and talk about potential solutions. And we'll show some
demos along the way too.

5. Docker, Mesos, Kubernetes,
and...Puppet? Don't panic!
Because Puppet is a common language for delivering and operating
modern infrastructure, organizations that rely on Puppet find it easier to
adopt new technologies. Project Blueshift represents Puppet's
engagement with our community – as well as with leading-edge
technologies like Docker, Kubernetes and Mesos, and their
communities – to make it possible to use Puppet to provide and
manage next generation software in a simple, reliable, and consistent
way. We'll discuss the current state and future plans for Blueshift, and
talk about the relationship between puppet and all the shiny new things
happening in the operations universe.

6. There is a Storm Coming:
Untangling the Strings of Your
Puppet
This session aims to discuss how the complexity on your Puppet
repository can frustrate your team and the new hires. The importance
of step back once in awhile and take a look at the path your repository
is taking and how meaningful tools like Pull requests, and code review
are for a team.

Running Puppet Software in
Docker Containers
Containers are an increasingly interesting way of packaging and
running software. What happens if we package Puppet software into
containers? What challenges arise and what new capabilities present
themselves? In this demo-heavy talk we will: * Package up Puppet
software (like Puppet Server, Puppet agents, PuppetDB and more) as
Docker containers. * Demonstrate Puppet running on container-centric
operating systems like CoreOS, using containers as the runtime. *
Stand up various Puppet stacks using Docker Compose. * Show how
to run Puppet software on top of cluster managers like Kubernetes. *
Discuss a number development and testing use cases that are made
easier using containers.

8. Heresy in the Church of Docker
Docker (and by extension, microservices-based architecture) has
expanded our horizons with respect to how the industry builds and
supports applications at scale, which helps to explain why so many
people seem willing to throw away decades of experience in favor of
untested tools and barely functional design principles. In this
entertaining and somewhat irreverent talk, Corey presents the "other
side" of the containerization craze: how configuration management fits
into a world consumed by the DockerDockerDocker madness, how
"containers all the way down" can blow up in your face when you least
expect it, and how promising technologies should perhaps be vetted a
bit more thoroughly before you try to run a hospital on top of them.
