November Meetup

Hi everyone!

This is the last Docker Dublin Meetup of 2018 and it's going to be jam packed with containerized goodness!

Please RSVP "Yes" only if you are intending to attend. We have had alot of no-shows and last minute changes at the last few Meetups. Thank you.

Our first set of speakers are Robert Mason (Principal Engineer) and David Balazs (Senior Associate Developer) from Workday.

Title:
Reconciling application team innovation with enterprise concerns using Kubernetes Dynamic Admission Control

Problem:
Workday provides a suite of hosted ERP software to customers both from our own data centres and more recently from public cloud.
We have moved to a containerised delivery model and use Kubernetes for orchstration and management of the delivery.
We want to empower our application teams to engage with the delivery model and innovate quickly but at the same time ensure that broader organisational requirements (e.g. Monitoring, TLS to Pod, Operational policy) can be delivered

Approach:

• Allow application development teams to deliver their service in helm charts without detailed knowledge of environment specifics and broader organisational requirements

• Leverage Kubernetes Dynamic Admission Control paradigm to ensure all application services are decorated with correct capabilities and configuration for the specific environment at deployment time

Talk Outline:

• The Kubernetes admission control pipeline

• InitContainer and Sidecar concepts

• How to build Kubernetes web hooks (mutating and validating)

• Signalling between application deployments and the admission control pipeline using annotations

The second talk of the night is from Thomas Shaw (System Engineer, Riot Games). Thomas will be asking the question "5 years later, is Docker still delivering?". A critical look over the past 5 years and our journey towards a containerized production. This talk was originally given at DockerCon US 2018.

See you on November 22nd!
