Join us for this CoreOS Berlin Meetup featuring two Software Engineers from CoreOS (@CoreOS). The first talk will feature Derek Gonyeo who will talk about Ignition. Ignition is the utility used by CoreOS Linux to manipulate disks during the initramfs. The second speaker, Frederic Branczyk, will talk about the latest releases of the Alertmanager introduced a high availability mode.

Snacks and beverages will be provided.

[18:30- 19:00] Arrive and mingle
[19:00 - 19:35] Derek Gonyeo - “Config Transpiler & Ignition Configs”
[19:40 - 20:15] Frederic Branczyk - “Alertmanager on its way to high availability”

[20:15 - 21:00] Mingle time

“Ignition & config transpiler (ct)”, Derek Gonyeo
Abstract: When a CoreOS Container Linux machine first boots, a configuration file can be provided to provision the machine. These files, called Ignition configs, can be tedious to write and aren't really designed to make it easy for humans to create them. A new tool, called the config transpiler (ct for short), aims to help with this. Users can write Container Linux Configs, which are much more easily editable YAML files, and use ct to validate them and convert them into Ignition configs.
This talk will introduce ct, explain the rationale behind both Ignition and ct, walk through a few examples with ct, and do live demos of booting machines with the examples.
“Alertmanager on its way to high availability”, Frederic Branczyk

Abstract: The latest releases of the Alertmanager introduced a high availability mode. Frederic will guide you through the contract of Prometheus and Alertmanager and why developing the high availability mode is unique to the problem the Alertmanager solves by giving an introduction into the principles used to implement it.

Derek Gonyeo, Software Engineer from CoreOS - Derek is visiting Berlin from the San Francisco office. He's worked on the rkt team for over a year, working on components like acbuild and docker2aci. More recently he switched to the OS team, working to polish and add functionality to ignition and ct. He graduated from RIT in 2016.
Frederic Branczyk, Software Engineer from CoreOS - Frederic contributes to Prometheus and Kubernetes to build state-of-the-art modern infrastructure and monitoring tools. He discovered his interest in monitoring tools and distributed systems in his previous jobs, where he used machine learning to detect anomalies indicating intrusion attempts. He also worked on projects involving secrets management for distributed applications to build sane and stable infrastructure.
