Setting up an on-premise Kubernetes environment

There are certain important considerations when implementing a Docker based environment, especially when the environment has to be setup on-prem, and has to adhere to existing ITIL processes. Following are some of the considerations that are often encountered when implementing a Docker based environment.

  • Docker Host – Whether to run the containers on baremetal or on virtual machines. How to manage the lifecycle of hosts?
  • Docker Storage for Containers – Which one to choose from OverlayFS, AUFS, Devicemapper etc.
  • Docker Storage for Volumes – NFS, SAN, GlusterFS, Ceph etc
  • Host and Container Networking – Whether to use overlay or not.
  • Docker Orchestration – Functionalities like user authentication & authorization, exposing of services, resource management, HA, backup etc are specific to orchestration software.
  • Docker Image Build & Distribution – What base image to be used, handling multi-architecture builds, scanning and certification of images, whether to use public registry or private registry are important decision points.
  • Logging
  • Monitoring

The choices will ofcourse vary and will be dictated by factors specific to each implementation.

I was fortunate to share my learnings w.r.to Kubernetes in the recently concluded Bangalore Container Conference 2017 and had some great discussions with folks having similar experiences in production Docker/Kubernetes deployments. You can find the full slides of the talk in the following link – http://www.slideshare.net/CodeOps/on-prem-container-cloud-lessons-learned

Please share your experiences on production deployments of Docker environments in the comments section. Would love to learn from your experiences.
