# Pre-requirements

- Kubernetes concepts

(pods, deployments, services, labels, selectors)

(building images, running them; doesn't matter how exactly)

- Familiar with the UNIX command-line

## Labs and exercises
|
||||
|
||||
- We are going to build and break multiple clusters
|
||||
|
||||
- Everyone will get their own private environment(s)
|
||||
|
||||
- You are invited to reproduce all the demos (but you don't have to)
|
||||
|
||||
- All hands-on sections are clearly identified, like the gray rectangle below
|
||||
|
||||

|
||||

|
||||
|
||||
## Private environments
|
||||
|
||||
- Each person gets their own private set of VMs
|
||||
|
||||
- Each person should have a printed card with connection information
|
||||
|
||||
- We will connect to these VMs with SSH
|
||||
|
||||
(if you don't have an SSH client, install one **now!**)
|
||||
|
||||
---
|
||||
|
||||
## Doing or re-doing this on your own?
|
||||
|
||||
- We are using basic cloud VMs with Ubuntu LTS
|
||||
|
||||
- Kubernetes [packages] or [binaries] have been installed
|
||||
|
||||
(depending on what we want to accomplish in the lab)
|
||||
|
||||
- We disabled IP address checks
|
||||
|
||||
- we want to route pod traffic directly between nodes
|
||||
|
||||
- most cloud providers will treat pod IP addresses as invalid
|
||||
|
||||
- ... and filter them out; so we disable that filter

## Hands-on sections
|
||||
|
||||
- There will be *a lot* of examples and demos
|
||||
|
||||
- We are going to build, ship, and run containers (and sometimes, clusters!)
|
||||
|
||||
- If you want, you can run all the examples and demos in your environment
|
||||
|
||||
(but you don't have to; it's up to you!)
|
||||
|
||||
- All hands-on sections are clearly identified, like the gray rectangle below

|

|

|

## If you're attending a live training or workshop
|
||||
|
||||
- Each person gets a private lab environment
|
||||
|
||||
(depending on the scenario, this will be one VM, one cluster, multiple clusters...)
|
||||
|
||||
- The instructor will tell you how to connect to your environment
|
||||
|
||||
- Your lab environments will be available for the duration of the workshop
|
||||
|
||||
(check with your instructor to know exactly when they'll be shutdown)
|
||||
|
||||
---
|
||||
|
||||
## Running your own lab environments
|
||||
|
||||
- If you are following a self-paced course...
|
||||
|
||||
- Or watching a replay of a recorded course...
|
||||
|
||||
- ...You will need to set up a local environment for the labs
|
||||
|
||||
- If you want to deliver your own training or workshop:
|
||||
|
||||
- deployment scripts are available in the [prepare-labs] directory
|
||||
|
||||
- you can use them to automatically deploy many lab environments
|
||||
|
||||
- they support many different infrastructure providers

## Why don't we run containers locally?
|
||||
|
||||
- Installing this stuff can be hard on some machines
|
||||
|
||||
(32 bits CPU or OS... Laptops without administrator access... etc.)
|
||||
|
||||
- *"The whole team downloaded all these container images from the WiFi!
|
||||
<br/>... and it went great!"* (Literally no-one ever)
|
||||
|
||||
- All you need is a computer (or even a phone or tablet!), with:
|
||||
|
||||
- an Internet connection
|
||||
|
||||
- a web browser
|
||||
|
||||
- an SSH client

## SSH clients
|
||||
|
||||
- On Linux, OS X, FreeBSD... you are probably all set
|
||||
|
||||
- On Windows, get one of these:
|
||||
|
||||
- [putty](http://www.putty.org/)
|
||||
- Microsoft [Win32 OpenSSH](https://github.com/PowerShell/Win32-OpenSSH/wiki/Install-Win32-OpenSSH)
|
||||
- [Git BASH](https://git-for-windows.github.io/)
|
||||
- [MobaXterm](http://mobaxterm.mobatek.net/)
|
||||
|
||||
- On Android, [JuiceSSH](https://juicessh.com/)
|
||||
([Play Store](https://play.google.com/store/apps/details?id=com.sonelli.juicessh))
|
||||

||||
*You don't have to use Mosh or even know about it to follow along.
|
||||
<br/>
|
||||
We're just telling you about it because some of us think it's cool!*
|
||||
|
||||
- Mosh is "the mobile shell"
|
||||
|
||||
- It is essentially SSH over UDP, with roaming features
|
||||
|
||||
- It retransmits packets quickly, so it works great even on lossy connections
|
||||
|
||||
(Like hotel or conference WiFi)
|
||||
|
||||
- It has intelligent local echo, so it works great even in high-latency connections
|
||||
|
||||
(Like hotel or conference WiFi)
|
||||
|

- It supports transparent roaming when your client IP address changes
