Recap of 2016: Docker 1.13, Container MELIG

One new-years-resolution is to be a better host. :)

So let's kick it off by looking back to 2016 in terms of Linux containers and MELIG in this regards.

Intro:

• Refresh audience on Linux Containers (Namespaces/CGroups), contrast to VMs
• High-level relevance for HPC and High-Performance Big Data
  Progress:
• Show Docker progress in 2016 (from 1.11 upwards)
  > independent runtime
  > integrated SWARM
  > ingress load-balancing
  > host network-mode
  > docker secrets
  > Looking forward to 1.14 (if possible)
  Ecosystem:
• Container engines
• Container Operating Systems
• Container Orchestration
  Explore-List (from last year's State of Linux Containers (https://www.youtube.com/watch?v=3gTJj-HuZuo&feature=youtu.be&list=PLfE3_wJGw9KS3PBvqEcDdpiODeDjAs5v8&t=1367)):
• Small vs. Big Containers: small!
• One vs. many processes: one!
• Docker Networking
• service discovery
• orchestration
• immutable containers vs. config mgmt
• Container Momentum: still hard in HPC, easier in BigData
• Separation of Concerns: kcompose, shifter/singularity
  New Items for the List:
• CI/CD: DroneCI, GoCD
• support of containers in HPC schedulers - or lack thereof
• service/container discovery
• monitoring, logging, inventory and OpenTracing
