What's new in Kubernetes 1.3? New things like: Petsets, init-containers, ubernetes, federated clusters, improved kubernetes UI, minikube, support for rkt, etc. Also find out sources to learn Kubernetes, how to participate with k8s community.

1. What’s new in Kubernetes 1.3
Suraj Deshmukh @surajd_

2. About me:
● Work at Red Hat on project kompose in Developer Tooling Team
● python and golang programmer
● Open Source enthusiast
● Likes to share knowledge
● surajd in [irc, slack], surajssd in [github], surajd_ in [twitter]
● Blog: https://deshmukhsuraj.wordpress.com/

3. init-containers
● Sequential pod initialization
● They can perform initialization of shared volumes, or configuration
● Delay the startup of application containers until pre-conditions are met
● Register pod with other components of system
● Its alpha in 1.3

4. Demo
Recorded Video Link: Watch here

5. PetSet
● Applications that need PersistentDisks, Stable Hostnames, Lifecycle
Actions, Identities in a Group a.k.a Clustered Applications
● Now you can run clustered applications on k8s
● An ordinal index of Pets: 0, 1, 2, 3, etc
● Stable storage linked to hostname of Pet.
● Applications like Cassandra, Zookeeper, etcd, etc. can now run on k8s.
● Alpha in k8s 1.3

7. Kubernetes Cluster Federation a.k.a.
Ubernetes
● Bring in multiple clusters across different regions, cloud providers, or on
premise installations into single interface.
● Load balance across multiple clusters
● Use when your application need HA, wanna make it globally available,
wanna make use multiple cloud providers, wanna mix usage of on-premise
and public cloud simultaneously, etc.

8. ● You can provide HA for your application across regions and Cloud
providers.
● location affinity, cross-cluster scheduling, service discovery and
application migration
● Pods in your application can do service discovery
● Beta in k8s 1.3
● Demo: https://github.com/kelseyhightower/kubernetes-cluster-federation

9. MiniKube
● Single node Kubernetes on your laptop.
● For users who wanna try it or develop with it on daily basis.
● It’s a Linux VM that has Docker and Kubernetes.
● Uses libmachine for provisioning VMs.
● Limitations: cannot use things that need cloud, like LoadBalancers,
PersistentVolumes, Ingress, etc.

10. Demo

11. Kubernetes UI
● Not a new release, but many new things added in this release
● Shows all the resources
● You can edit the resources in the dashboard itself
● Also a view cluster nodes

12. rkt support
● Rkt is container runtime from CoreOS
● With this release rkt is also a first class citizen of Kubernetes world
● So k8s has pluggable container runtime environments.
