“Kubernetes is an open-source platform designed to automate

deploying, scaling, and operating application containers."

Initial release: 7 June 2014

@bridgetkromhout #devopsdays

containers: present day

@bridgetkromhout #devopsdays

containers

treat as a tool, not a goal be aware of complexity

@bridgetkromhout #devopsdays

kubernetes

@bridgetkromhout #devopsdays

Massively scalable fault-tolerant distributed systems require a

significant engineering effort to build and operate; complex socio-technical systems are even more challenging.

Computers are easy; people are hard

kubernetes

orchestration is only one part wider ecosystem considerations

@bridgetkromhout #devopsdays

silos are for grain

not actually devops

still computers
