This document provides an overview of orchestration using Kubernetes, focusing on Azure Kubernetes Service (AKS) and the use of Minikube. It covers key Kubernetes concepts such as namespaces, pods, services, deployments, and statefulsets, emphasizing their roles in managing containerized applications. Additionally, it includes links to resources, demos, and videos for further learning and understanding of Kubernetes and AKS.

7. Container
Orchestration

8. Need for Orchestration
• Deploy Multi-container apps
• Scale containerized apps
• Roll out new versions of apps without
downtime
• Provide networking, service discovery and
storage
• Manage resources across multiple containers
• Self healing

9. DEMO

Kubectl

10. Kubernetes
Open-source system for automating deployment, scaling, and
management of containerized application across clusters of
machines
Basic Objects
- Namespace
- Pod
- Volume
- Service
Controllers
- ReplicaSet
- Deployment
- StatefulSet
- DemonSet

11. Kubernetes - Pod
- Smallest unit of deployment
- Group of one or more
containers
- Contains specification how
to run container along with
its related resources
(storage / networking)

12. Kubernetes - Deployment
- Desired state definitions for pods and
replica sets
- Defines
- version of container images
- number of replicas
- update strategy
- Metadata to interact with resources

13. DEMO
Namespace,
Deployment

14. Node 2
Kubernetes - Service
- Acts as Load Balancers for
pods
- Provides stable IP for
consumers
Node 1
TechTalksWeb
Pod1
TechTalksAPI
Pod2Pod1

15. Kubernetes - StatefulSet
- Use StatefulSets when data loss is unacceptable
- Useful when replicas are needed for availability
or scalability, and the replicas need stable
volume mounts across restarts
- Often used when deploying database workloads
that store their state on external storage providers
- With StatefulSets a crash of pod or cluster
does not result in data loss
