Bryan Hunt
Open source contributor, solutions architect at Erlang solutions
Bryan is a long time programmer whose career has spanned Perl, ASP, Enterprise Java, Erlang and now Elixir. He's been building software to run on Linux systems since the 90s and worked with all sorts of weird and wonderful virtualisation. Right now, his primary deployment focus is on Kubernetes. He came from the world of eventually consistent via Riak (Dynamo paper implemented in Erlang) but recently has been riding more on the strongly consistent side of the wave. His favourite things include, but are not limited to, the great outdoors, hillbilly music and working/hunting dogs.

Code BEAM STO V
09.00 - 17.00
Clueful Elixir with Kubernetes
Deploying, running, operating and debugging Elixir and Erlang applications on Kubernetes doesn’t have to be a big deal once you know a couple of basic tricks and patterns.
In this one-day tutorial, you will learn to build, deploy, scale and cluster Elixir applications on Kubernetes.
OBJECTIVES
When you've completed this tutorial, you will:
- Have a deeper understanding of Kubernetes
- Know how to operate an Elixir cluster deployed on Kubernetes
- Know how to set up monitoring Know how to debug issues
- Know how to template configuration for deployment in multiple environments
- Learn the techniques for keeping secrets secret
Most of the class will be live coding together. You'll have plenty of time to work on labs along the way as you hone your skills. About half of the class is either lab work or coding side-by-side with your instructor.
PREREQUISITES
Attendees should have a basic understanding of Elixir applications, releases, distributed Erlang, and Docker.
Please have docker for Mac (edge) installed on their machine (Kubernetes supported out of the box)(preferable), a working Kubernetes instance, or use a provided GKE Google Kubernetes Engine instance.
TARGET AUDIENCE
Elixir/Erlang developers with basic knowledge of Docker wishing to expand their operational ability of running BEAM applications on Kubernetes.
COURSE OUTLINE
- Best practice for building docker images of Elixir applications
- Using distillery for building releases
- Using libcluster for automatically forming Elixir clusters
- Integrating Prometheus/Grafana monitoring
- Debugging deployment issues
- The characteristics of the different Kubernetes controllers
- How to leverage Kube DNS
- Autoscaling
- Working with dependencies and private repositories
- Startup failure and health checks
- Exposing Kubernetes applications to the internet (GKE)

Panel Discussion: The number of orchestration technologies is too damn high!
Service orchestration technologies are an essential tool to manage the chaos of modern application development and infrastructure scaling, but the choices can feel overwhelming. Where should a team get started on their service orchestration journey? How do they ensure this choice can benefit the team’s use case for years to come? David Schainker will facilitate a panel bringing the expertise of Jani Leppanen, Verónica López, Thomas Depierre, and Brian Hunt with the goal of bringing clarity to the fog of such decision making.
Our panelists will discuss their orchestration technology of choice and why it matters to them. We’ll hear about how to learn the ropes, how these technologies boost developer efficiency, how to staff the team to use this technology, and how to get management on board with leveraging newfound efficiencies.

Customer retention and how to avoid double billing
My talk will discuss several techniques to prevent double billing during the booking/checkout process. I'll start with simple relational datatabase techniques and work up to distributed CP, and AP implementations. I will also show how modeling a customer activity as an Elixir processes state provides an excellent means to ensure reliable ordere processing.
THIS TALK IN THREE WORDS
Transactions
Modelling
Transactions
OBJECTIVES
Demonstrate simple techniques to prevent double booking - two phase commit using RDBMS, Riak, and a strongly consistent distributed DB. Demonstrate the trade-offs and implementation details.
TARGET AUDIENCE
Elixir/Erlang developers who want to ensure their check-out process works correctly.
