Class Materials for Kubernetes Training.

Kubernetes Class

This repository contains the labs and scripts for a Cisco Kubernetes class offered by Cisco.

Summary

After taking this class, attendees will feel comfortable with the following Kubernetes topics:

• Metacloud - Basic intro to the OpenStack solution which Kubernetes run on top of
• Kubernetes components
• Deploying Kubernetes
• Basics of Kubernetes
• Deploying/scaling apps in Kubernetes

Additionally, hands-on labs will provide real world experience with Kubernetes.

DISCLAIMER Many Kubernetes tutorials use GCE or AWS. This material uses OpenStack, specifically, Cisco's OpenStack offering, Metacloud.

It is recommended to first print the Reference page. This way you can record some variables you set for later use in the labs.

Labs

• Reference - Start by printing this for your reference
• 00 -Metacloud Introduction - This lab covers a basic overview of Metacloud.
• 01 Environment Setup - This lab covers setting up your lab VM for the rest of the labs
• 02 Installation Lab - This lab covers installing Kubernetes. We use a Terraform script to bring it up quickly. Its done on Metacloud.
• 03 Configuration Lab - This lab covers getting kubectl configured to work with our lab environment as well as the final touches of networking required to make our kubernetes cluster functional.
• 04 Running Kubernetes - This lab covers deploying and managing applications in our operational kubernetes environment.
• 05 Kubernetes ops - This lab covers some additional basic operations in Kubernetes.
• CI/CD Lab - WIP
• Monitoring - WIP

k8sclass's Issues

fix typo in guestbook image

change redis slaves to RS instead of RM

update lab0

Adding some clarification to lab0

Minor typo: Kubernetes Lifecycles Operations

Not sure if you guys use this same set of instructions elsewhere, so feel free to ignore, but Step 1 of the last module has a minor typo:

kubectl decsribe deployment frontend

should be

kubectl describe deployment frontend

Add links to next lab at bottom of each page

More context for kubectl

lab04 - additions?

Have a section where they just install nginx as an example (would require exposing service, maybe delete it then do guestbook install?

Additional notes:

• discuss namespaces?
• create some fun labels?
• upgrade a component of the app?

Lab 02 - mentions line 25

What is this supposed to be?

Fix race condition when running terraform apply

Tries to copy the certs before they are created.

make syntax consistent

Go through all labs, making syntax consistent. One thing that sticks out is commands. Should they be bold everywhere or in between ``` ?

chaos monkey to create a failure?

lab04

update image to reflect 2 redis-slaves instead of 3

lab00 - feedback

Some feedback that lab00 is a little confusing trying to track down the details for the profile. I'm wondering if it would be more streamlined if we swapped lab0 and lab1

Add diagram of what environment looks like from a VM perspective

Add an architectural diagram of what the environment looks like:

Consistencies with instance names in docs

We should probably make sure the docs naming convention is consistent across the labs... ie. dragon-controller vs jd_controller01...

Change colors of items that need to be modified

It would be helpful if we could change all items that need to be modified (text in < >) to a different color so it stands out more.
