Minutes for 2018-04-24

Minutes taken by: Zachary Seguin

Introduction

Canadian Digital Services - Collaboration Room

  • Canadian Digital Services / Statistics Canada organized
  • Importance of Cloud native
  • As Developers our view points aren’t always appreciated
  • Policy makers make decisions and we enact it

Minutes

But first we need to quickly go over some highlight from the minutes during the last meetup.

  • Review of planning decisions from last meeting
  • Website govcloud.ca
  • More documentation being pushed to YouTube
  • Will cut out planning discussion from video minutes
  • Will upload 1.5hrs in chunks
  • AKS / ACS (Benefits / Comparisons)
  • ACS Engine
    • Take bare minimum cluster definition (small JSON) which then generates ARM templates
    • For operators that need complete control and customizability
    • Deploys cluster on Ubuntu
    • OpenShift support also being added
    • Can add custom extensions (e.g., choco)
  • Autoscaler
  • Heptio Ark: Must have for any cluster
  • VS Code: Many Kubernetes / Helm integration
  • JupyterHub and custom developer environments
  • Distributed Logging with EFK
  • Pachyderm

What kind of applications are people consider containerizing?

  • Identity management platform (6 services together) - Pat, Public Works
    • Working locally, automated pipeline, test
    • Alpine Linux, a few that are Ubuntu (more for COTS)
    • GitLab CI
  • Data science framework (spark, Hadoop, Drupal, etc.) - Will, Statistics Canada
    • Horizontal services that devops can deploy and maintain to support dev groups
    • Private NuGet repo, Jenkins, GitLab, etc.
    • Windows 17.09 or higher (Azure, Kubernetes) due to networking issues
    • Build containers for non-core applications of .NET
  • Best ways to set up local:
    • Easiest: Docker for Mac / Windows (currently in edge)
    • Hyperkube, Kubespray

Upcoming Presentations

  • Next meet up by Laurent (co-maintainer of Node.JS container)
  • After that, Zachary with OpenFaaS
  • Mark w/ Windows Workloads (.NET, CI/CD, Jenkins, etc.)

Planning

  • Review of planning decisions from last meeting
  • Website govcloud.ca
  • Documentation on YouTube after its done
  • Will cut out planning discussion from last time
  • Will upload 1.5hrs in chunks

AKS (Azure Kubernetes Service)

  • Downside: cannot customize the master
  • Downside: no custom VNETS
  • Fixed in ACS engine, and will eventually make its way up to AKS.
  • Standard D4s_v3 (16GB RAM, 4 cores) (v3 or higher for nested virtualization)
  • Templates are not stored by you (ARM templates, etc.)
  • Works in Canada East with 1.9.6 (some extensions have issues)

Azure Container Service (ACS)

  • Exact same as AKS, but gives you the master
  • Similar downsides as AKS

ACS Engine

  • Take bare minimum cluster definition (small JSON) which then generates ARM templates
  • For operators that need complete control and customizability
  • Deploys cluster on Ubuntu
  • OpenShift support also being added (changes to 1 line)
  • Can add custom extensions (e.g., choco)

Autoscaler

  • Gave a brief demo

Heptio Ark

  • A must-have on any cluster

Distributed Logging

  • EFK (Elasticsearch, Fluentd, Kibana)

Jupyterhub

VS Code

  • You can preview templates (Helm: Preview template)
  • VSCode has great integration with Kubernetes
