Introduction

When applications are running in production, they become black boxes that need to be traced and monitored. One of the simplest, yet main, ways to do so is logging. Logging allows us - at the time we develop our software - to instruct the program to emit information while the system is running that will be useful for us and our sysadmins.

get contexts

alias k=kubectl
k config get-context
k config current-context
echo " k config current-context" > /opt/course/1/context_default_kubectl.sh
chmod +x /opt/course/1/context_default_kubectl.sh
bash /opt/course/1/context_default_kubectl.sh
cat .kube/config | grep current

KUBERNETES CLUSTER

local https://github.com/kubernetes-sigs/kind (or just use minikube if it works for you)
cloud https://cloud.google.com/kubernetes-engine (for PersistentVolume and Ingress, I needed to try the real deal)

PRACTICE

Requirements

There are 18 questions in total. You will need five RHEL 8 (or CentOS 😎 virtual machines to be able to successfully complete all questions.

Optional Automatic Exam Setup Available

Here is an automated exam environment deployment for Mac/Linux/Windows that deploys the practice exam environment for you, including IPA server/client installation and configuration. You can also use your own lab environment. Navigate to the respective repo you wish to use for this practice exam and follow the README instructions:
