# Our sample application
No assignment
# Kubernetes concepts
Do we want some kind of multiple-choice quiz?
# First contact with kubectl
Start some pre-defined image and check its logs
(Do we want to make a custom "mystery image" that shows a message
and then sleeps forever?)
Start another one (to make sure they understand that they need
to specify a unique name each time)
Provide as many ways as you can to figure out on which node
these pods are running (even if you only have one node).
# Exposing containers
Start a container running the official tomcat image.
Expose it.
Connect to it.
# Shipping apps
(We need a few images for a demo app other than DockerCoins?)
Start the components of the app.
Expose what needs to be exposed.
Connect to the app and check that it works.

## Assignment: get Kubernetes
- In order to do the other assignments, we need a Kubernetes cluster
- Here are some *free* options:
- Docker Desktop
- Minikube
- Online sandbox like Katacoda
- You can also get a managed cluster (but this costs some money)
---
## Recommendation 1: Docker Desktop
- If you are already using Docker Desktop, use it for Kubernetes
- If you are running MacOS, [install Docker Desktop](https://docs.docker.com/docker-for-mac/install/)
- you will need a post-2010 Mac
- you will need macOS Sierra 10.12 or later
- If you are running Windows 10, [install Docker Desktop](https://docs.docker.com/docker-for-windows/install/)
- you will need Windows 10 64 bits Pro, Enterprise, or Education
- virtualization needs to be enabled in your BIOS
- Then [enable Kubernetes](https://blog.docker.com/2018/07/kubernetes-is-now-available-in-docker-desktop-stable-channel/) if it's not already on
---
## Recommendation 2: Minikube
- In some scenarios, you can't use Docker Desktop:
- if you run Linux
- if you are running an unsupported version of Windows
- You might also want to install Minikube for other reasons
(there are more tutorials and instructions out there for Minikube)
- Minikube installation is a bit more complex
(depending on which hypervisor and OS you are using)
---
## Minikube installation details
- Minikube typically runs in a local virtual machine
- It supports multiple hypervisors:
- VirtualBox (Linux, Mac, Windows)
- HyperV (Windows)
- HyperKit, VMware (Mac)
- KVM (Linux)
- Check the [documentation](https://kubernetes.io/docs/tasks/tools/install-minikube/) for details relevant to your setup
---
## Recommendation 3: learning platform
- Sometimes, you can't even install Minikube
(computer locked by IT policies; insufficient resources...)
- In that case, you can use a platform like:
- Katacoda
- Play-with-Kubernetes
---
## Recommendation 4: hosted cluster
- You can also get your own hosted cluster
- This will cost a little bit of money
(unless you have free hosting credits)
- Setup will vary depending on the provider, platform, etc.
---
class: assignment
- Make sure that you have a Kubernetes cluster
- You should be able to run `kubectl get nodes` and see a list of nodes
- These nodes should be in `Ready` state
