This document provides an introduction to orchestrating software deployments with Kubernetes. It discusses common challenges like deploying code to the cloud, horizontal scaling, rollouts and rollbacks that Kubernetes addresses. The basics of Kubernetes components like pods, deployments and ingress are explained. It also gives an example of creating a Kubernetes deployment and lists some important Kubernetes commands.

11. Kubernetes components

13. ● Cluster (set of nodes)
Start with a cluster instead of the nodes
● Node
Basic unit of computing hardware (single machine in your cluster)
● Persistent Volumes
Integrated with cloud providers such as Azure, AWS and Google Cloud
Kubernetes components

14. ● Pods
○ collection of one or more containers sharing the same resources and
local network
○ Pods are used as the unit of replication
● Deployments
○ Manage pods
○ Declare how many replicas of a pod should be running at a time
○ Monitor pods. If a pod dies, the deployment will automatically re-
create it
Kubernetes components

15. ● Ingress
○ Load balancing
○ SSL termination
○ Name-based virtual hosting
● Configmap
○ Encrypted key value database
○ Store environment variables
○ Store certificates
○ Store credentials

17. 1. Install beta version Docker from beta.docker.com
2. brew install kubectl
3. kubectl create -f example.yaml
Installation

18. kubectl get all
kubectl logs <pod-name>
kubectl delete -f sample.yaml
kubectl describe replicasets
kubectl exec <pod-name> -i -t -- bash -il
Other important commands
