# 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.

## Get Kubernetes
|
||||
|
||||
- In order to do the other labs and exercises, we need a Kubernetes cluster
|
||||
|
||||
- Here are some *free* options:
|
||||
|
||||
- Docker Desktop
|
||||
|
||||
- Minikube
|
||||
|
||||
- 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: 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.

## Setting `$REGISTRY` and `$TAG`
|
||||
|
||||
- In the upcoming exercises and labs, we use a couple of environment variables:
|
||||
|
||||
- `$REGISTRY` as a prefix to all image names
|
||||
|
||||
- `$TAG` as the image version tag
|
||||
|
||||
- For example, the worker image is `$REGISTRY/worker:$TAG`
|
||||
|
||||
- If you copy-paste the commands in these exercises:
|
||||
|
||||
**make sure that you set `$REGISTRY` and `$TAG` first!**
|
||||
|
||||
- For example:
|
||||
```bash
|
||||
export REGISTRY=dockercoins TAG=v0.1
|
||||
```
|
||||
|
||||
(this will expand `$REGISTRY/worker:$TAG` to `dockercoins/worker:v0.1`)
