Kubernetes (K8s) • Kicked off by Google’s Borg • Most active github project • Orchestration for containers, e.g. Docker • Declarative configuration • Service discovery • Rolling upgrades munz & more #23

Slide 24

Slide 24 text

K8s • YAML configuration • Pod: Container(s) sharing IP, network, filesystem – IP is ephemeral – Uses Labels • Replication Controller -> Replica Set – Manages PODs (restarts replicas based on labels) • Services – Proxy for pod – Permanent IP munz & more #24

Slide 25

Slide 25 text

Docker Swarm • Native Docker cluster with same API as a single engine -> part of Docker • Fast provisioning, about 500 msec • Scheduling: spread, binpack, rand • No insecure mode J munz & more #25

Slide 26

Design Goals for Mini • Hands-on Raspi experience • Distributed Kubernetes setup & Docker Swarm setup • HA / failover / rolling updates • Have a fun project munz & more #26 Others have build Raspi clusters as well and a lot of credit goes to them, e.g. to Roland Huss, Alex Ellis etc

Slide 27

Slide 27 text

Design Decisions for Mini • Hypriot Linux • 4 node cluster • ARM based -> runs ARM Docker images • Better I/O throughput due to separate WIFI chip • Wifi router in hotspot mode – Mac OS issue with NAT • DIY: github https://github.com/fmunz/raspicluster munz & more #27

Kubernetes or Swarm? • Swarm wasn’t impressive when released, but this has changed • Swarm is much easier to understand and to operate • Swarm covers a lot of what K8s does • Swarm is tightly linked to Docker API -> harder to replace Docker with e.g. Rocket munz & more #29

Slide 35 text

OCCS • Easy way to run Docker container in Oracle cloud • No need to install Docker, Kubernetes, buy machines etc. • Integrates with Docker hub and Oracle Container registry • Does not use Kubernetes or Docker Swarm

Wercker

Slide 47

Slide 47 text

Wercker • Recently acquired by Oracle • Pipelines execute steps on code – Pipelines == series of steps – Execute inside Docker container • Workflows == chained and branched pipelines • Quickly provision ready to run infrastructure – Push images to any registry – Restart OCCS via webhooks munz & more #47

Predictions • Swarm will take its share from Kubernetes. • OCCS is an easy solution in OPC • You will not dockerize 90% of your enterprise IT in the next 24 months. • Docker is like the new Linux. Be ready to experience that feeling we had with Linux 13 years ago J • Docker is (sometimes) the new PaaS. munz & more #50

TL;DR @docker #cloud Docker is used in production / cross cloud / just Docker is not enough / #swarm is the easier #k8s / not a security risk / many products offered as images / OCCS & Wercker saves you from heavy lifting / Oracle caught the trend! / consider cloud services. @frankmunz
