This document summarizes a presentation about containerization using Docker and Kubernetes. It introduces Docker as a tool for building and running containerized applications. Kubernetes is introduced as an open-source system for automating deployment, scaling, and management of containerized applications. The presentation demonstrates using kubectl and YAML files to interact with and define resources in a Kubernetes cluster, and discusses concepts like pods, deployments, services and ingress in Kubernetes.

- 5. Docker facts • founded as dotCloud Inc in 2010 and renamed in 2013 • Docker was an internal project to run platform-as-a-service services • Docker project was released as open source on March 2013 • Since then – Docker Hub – Docker EE – Docker Swarm – Docker on Windows – ... 5
- 7. But, what exactly are containers? A container consists of one or more processes that are isolated from the rest of the system. All files necessary for execution are provided by a separate image. 7
- 8. But, what exactly are containers? • As for Linux, the technology behind it is nothing new – chroot (introduced 1979) – namespaces (introduced in 2002) – cgroups (introduced in 2007) • Windows Container support since – Windows Server 2016 – Windows 10 Professional / Enterprise 8
- 9. Demo “Linux containers” • isolate a Linux userspace process using namespaces and chroot 9
- 10. Why do we need Docker than? • runc, runhcs (and others) – abstracts the underlying OS – runs containers. full stop. • containerd – adds support for container lifecycle – daemon process – can be used on it one (Kubernetes) • Docker Engine – adds support for Volumes, Networking – CLI and API – additional tools like “docker build” • there are others as well – https://medium.com/01001101/container-runtimes-838c26e8c1d 10
