Today:● kubectl rolling-update● sed (?!?)

ConfigMaps

Problem: Managing config separately from your applications

Today:● Build container with config ● Reconfigure app to use

external config store ● Run a sidecar container that pulls the config

from config store

ConfigMaps

Solution: ConfigMaps!● Late-binding, live-updated

and atomic ● Available as a file or env vars

DaemonSets

Problem: Run one (and only one) pod on every node (or a subset of nodes)

Today:● Over-replicate● Static pods● Grab unique resource per node● Run outside of Kubernetes

Roadmap

• Kubernetes 1.3 is weeks* away!• Legacy application support (aka Pet Set)• Cluster Federation (aka Ubernetes)• Scale++• In-cluster IAM• Cluster autoscaling• Scheduled job• Public cloud dashboard (with nightly runs)• Lots, lots more!

• Open for proposals now

* Where weeks = O(16)
