Workshop: Deploying and Scaling Node.js with Kubernetes
The document is a presentation on Kubernetes, an open-source system for automating the deployment, scaling, and management of containerized applications. It covers key concepts such as nodes, pods, replica sets, deployments, and services, along with their roles in container orchestration. The workshop concludes with resources for further learning and contact information for the presenters.

- 4. © 2016 NodeSource Welcome 4 Today’sRoadmap • Introduction to Kubernetes • Cloudy Time Machine Overview • Ship to production Just kidding!
- 5. © 2016 NodeSource ContainerOrchestration 5
- 6. © 2016 NodeSource6 Ifyour architecture looks like this Manage your containers with Ansible, Docker Swarm, Amazon ECS, etc.
- 7. © 2016 NodeSource7 Ifyour architecture looks like this You need orchestration help
- 8. © 2016 NodeSource OrchestrationOverview 8 Container Orchestration • Schedule containers to physical/virtual machines • Restart containers if they stop • Provide private container network • Scale up and down • Service discovery

- 11. © 2016 NodeSource Kubernetes101 11 Kubernetes Orchestration • Schedules containers to physical machines • Service discovery & load balancing • Horizontal application scaling • Automated rollouts & rollbacks • Secret and configuration management • Storage orchestration • … and a whole lot more!
- 12. © 2016 NodeSource KubernetesTerminology 12
- 13. © 2016 NodeSource Kubernetes101 13 Terminology - Nodes • Is a worker machine in Kubernetes that runs your containers • Node may be a VM or physical machine • Each Node has the services necessary to run Pods
- 14. © 2016 NodeSource Kubernetes101 14 Terminology - Pods • Smallest deployable unit of computing • Group of one or more containers • Containers within a Pod share a cluster-accessible IP address (and localhost) • Containers within a Pod of access to shared volumes
- 15. © 2016 NodeSource Kubernetes101 15 Terminology - Replica Sets • Ensures that a specified number of Pod “replicas” are running at one time • If there are too many, it will kill some Pods • If there are too few, it will start more
- 16. © 2016 NodeSource Kubernetes101 16 Terminology - Deployments • Provide declarative updates for Pods/Replica Sets • Manages one or more Replica Sets • Primary mechanism for interacting with Pods! • Automated rollouts and rollbacks :)
- 17. © 2016 NodeSource Kubernetes101 17 Terminology - Services • An abstraction which defines a logical set of Pods • Provides a mechanism for accessing them • 3 types: ClusterIP, NodePort, LoadBalancer
- 18. © 2016 NodeSource Kubernetes101 18 Terminology - Namespaces • Provide a virtual cluster backed my the same physical cluster • Namespaces provide a scope for names. Names of resources need to be unique within a namespace, but not across namespaces. • Divide cluster resources between multiple uses
