Rancher Labs Training
#rancherk8s

2. Today’s objectives Technical introduction to Kubernetes using Rancher
Keep the slides to a minimum
Demo, then demo some more
Questions are always welcome
We won’t leave until all your questions are answered!

13. Rancher & Kubernetes - better together
Open source container manager used to run Kubernetes in production
Easy-to-use interface for k8s configuration and deployment
Infrastructure management across multiple clusters and clouds
Automated deployment of the latest k8s release
Workload, RBAC, policy, and project management
24x7 enterprise-grade support
Rancher Kubernetes Distribution
Certified and supported distribution that closely follows the upstream Kubernetes project
Rancher Infrastructure Services
Storage, networking, load balancing, security, etc.

16. Kubernetes 101 Pods Deployments Services Config maps Ingresses
#rancherk8s

17. Pods Smallest unit that can be deployed in Kubernetes
Consist of one or more containers that are always scheduled together
Each pod is given a unique IP address
Containers in a pod can speak to each other via localhost
#rancherk8s

18. Pods are confusing
If the explanation is confusing, don’t worry too much
Pods typically contain only a single container
Try to think of pods as containers for the remainder of the training

19. Pods

21. Replication Controller and Replica Set
Defines the desired scale and state of a group of pods

22. Replica Set

23. Replica Set

24. Replica Set

25. Deployments Level of abstraction above ReplicaSets
Deployments create and update ReplicaSets
Allow you to easily scale and perform rolling upgrades

30. Deployments

31. Services
Define a DNS entry that can be used to refer to a group of pods
Provide a consistent endpoint for the group of pods
Different types: nodePort, clusterIP, loadbalancer
#rancherk8s

32. Services
Service IP

33. Config maps Allow storing of arbitrary configuration values and files
Exposed in pods as either environment variables or as local storage
Decoupled storage of configuration from pod spec
#rancherk8s

34. Config Maps apiVersion: v1 kind: ConfigMap metadata: name: dev-config
  namespace: default 
data: 
  Item1: dev-stuff 
  Item2: more dev stuff
apiVersion: v1 
kind: ConfigMap 
metadata: 
  name: dev-config 
  namespace: default 
data: 
  Item1: qa-stuff 
  Item2: more qa stuff
apiVersion: v1 
kind: ConfigMap 
metadata: 
  name: dev-config 
  namespace: default 
data: 
  Item1: prod-stuff 
  Item2: more prod stuff

35. Ingresses
Define how traffic outside the cluster is routed to inside the cluster
Used to expose Kubernetes services to the world
Route traffic to internal services based on factors such as host and path
Ingress is usually implemented by a load balancer (Nginx, HAProxy, AWS ELB, etc…)
