## 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
|
|
|
|
.lab[
|
|
|
|
- This is a command that we're gonna run:
|
|
```bash
|
|
echo hello world
|
|
```
|
|
|
|

## 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))
|
|
works pretty well
|
|
|
|
- Nice-to-have: [Mosh](https://mosh.org/) instead of SSH, if your Internet connection tends to lose packets
|

## What is this Mosh thing?
|
|
|
|
*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
|
|
|
|
(Like when you hop from hotel to conference WiFi)

## Using Mosh
|
|
|
|
- To install it: `(apt|yum|brew) install mosh`
|
|
|
|
- It has been pre-installed on the VMs that we are using
|
|
|
|
- To connect to a remote machine: `mosh user@host`
|
|
|
|
(It is going to establish an SSH connection, then hand off to UDP)
|
|
|
|
- It requires UDP ports to be open
|
|
|
|
(By default, it uses a UDP port between 60000 and 61000)
