1. What’s New in K8s 1.3 Carter Morgan @_askcarter @_askcarter
2. Background: 3 Hurdles @_askcarter
3. The App How do I write scalable apps? How do I package and distribute? What runtimes am I locked into? @_askcarter
4. The Infra Can I scale? Is it automatic? Am I locked in? @_askcarter
5. The Wild Where are my machines? How do I update? @_askcarter
6. Kubernetes Open Source Container Automation Framework • Open API • Based on Google’s experiences @_askcarter
7. 3 Claims @_askcarter
8. How does k8s hold up? @_askcarter
9. Kubernetes Pre 1.3 Horizontal Scaling Automated Rollbacks Container Scheduling Resource Quotas and Limits Self-healing Service Discovery and Load Balancing Secret and Configuration Management Daemon Sets Secrets and Config Maps Deployments (already had a lot) @_askcarter

33. 3 Claims: revisited @_askcarter
34. Kubernetes 1.3 @_askcarter
35. Kubernetes 1.3 @_askcarter
36. Kubernetes 1.3 Init containers (alpha) Fixed PDs Cluster Federation (alpha) Optional HTTP2 Pod Level QoS Policy Tls secrets kubectl set command UI Jobs RBAC (alpha, experimental) Garbage Collector (alpha) Pet Sets rkt Container runtime Network policies (and more) @_askcarter
37. Cluster Federation Manage clusters across region and providers @_askcarter
38. Jobs Pods *expected* to terminate Creates 1...n Pods and ensures that a certain number of them run to completion 3 types: non-parallel, fixed count parallel, and parallel with a work queue @_askcarter
39. Job: Work Queue with Pod Per Work Item @_askcarter
40. Init Containers Sequential Pod Initialization @_askcarter Pod Init 1 monolith NFS 10.1.0.100 Init 2 Init 3
41. Init Container: register pod to external service @_askcarter
42. Init Container: clone a git repo into a volume @_askcarter
43. Pet Sets Pods with ego Pods are fungible, stateless? Pets are Pods with: 1. Stable hostname 2. A unique name 3. Stable storage @_askcarter
44. Pet Sets Pods with ego @_askcarter
45. PetSet: example manifest @_askcarter
46. PetSet: headless service @_askcarter
47. Bonus @_askcarter
48. Google Container Engine (GKE) Cluster autoscaling (beta) IAM support Local SSD Container-VM Images (beta) Node pools @_askcarter
49. minikube github.com/kubernetes/minikube @_askcarter
