+# Kubernetes 101
+
+## An introduction
+
+---
+
+# Stuff you should already know
+
+- Containers
+- Container engines
+  - [docker][docker], [podman][podman] :heart:
+- Bonus points for:
+  - [docker-compose][docker-compose]
+  - [podman-compose][podman-compose]
+
+[docker]: https://www.docker.com/
+[podman]: https://podman.io/
+[docker-compose]: https://docs.docker.com/compose/
+[podman-compose]: https://github.com/containers/podman-compose
+
+<!--
+- podman can run root less
+- there is a docker-compose equivalent
+- compose is basically running a kubernetes like deployment
+-->
+
+---
+
+# Agenda part 1 - The basics
+
+- 🧑 Workloads aka your app
+- 🛋️ Environment
+- 📦 Containers
+- 🏡 Pods
+- 🏘️ ReplicaSets
+- 🏪 Services
+- 💾 Volumes
+- 🌆 Namespaces
+
+<!--
+If you want to explain it to your kid, you can stop after this.
+The emojis probably make no sense, ignore them if they confuse you.
+-->
+
+---
+
+# Agenda part 2 - Advanced topics
+
+- 🏭 Deployments
+- ? StatefulSets
+- 🌐 Ingress Controller
+- 📑 Cluster DNS
+- 💾 Container Storage Interface (CSI)
+- 🕸️  Container Network Interface (CNI)
+  - 👮 Network Policies
+- 🃏 Custom Resources
+
+<!-- It's ok if you zone out somewhere around here. -->

+

+
+# 🧑🛋️  Workloads and their environment
+
+Example: Simple PHP app
+
+- index.php
+- PHP runtime ([php-fpm][php-fpm])
+- Webserver ([NGINX][nginx])
+- OS ([Alpine][alpine])
+
+[php-fpm]: https://www.php.net/manual/en/install.fpm.php
+[nginx]: https://www.nginx.com/
+[alpine]: https://www.alpinelinux.org/

+
+![bg right 80%](./container.drawio.svg)
+
+# 📦 Containers
+
+- Isolated environment
+  - Linux namespace and cgroups
+- Networking?
+- Persistant storage?
+- Scheduling, Load balancing
+
+<!-- Networking: I smell another talk around here -->
+

+
+![bg right 80%](./pod.drawio.svg)
+
+# 🏡 Pods
+
+- "Runnable unit of work"
+- Holds Containers
+- Connects to overlay network
+- Container runtime interfaces (CRI)
+  - containerd, CRI-O, Docker
