Overview

The objective of the training is to acquire Kubernetes Administration basics :

  • Learn about container orchestration
  • Master the installation, configuration of a Kubernetes platform
  • Understand the main types of objects managed by Kubernetes
  • Know how to deploy applications on Kubernetes
  • Be able to debug and observe applications and the Kubernetes cluster itself

The training consists of about 50% theory and 50% hands-on labs.

Note: Although the training is a good preparation for the CKA certification, it can also be combined with the “K8S-004-EN CKA Exam Preparation” training.
This day is dedicated to practical exercises to help pass the certification.
It is recommended to take the preparation training a week later to properly fix the learnings.

This is what you will learn

The training participant will acquire Kubernetes Administration basics, in particular :

  • Installation, Configuration, Upgrading of a Kubernetes Cluster
  • Deploying and upgrading applications on Kubernetes
  • How to expose applications
  • Use of external data volumes
  • Observation, debugging of applications & of the cluster
  • Security & Best practices

Requirements and target audience

This training is ideal for engineers with little or no experience with Kubernetes administration.
Participants must provide their own PC with internet access, with the ability :

  • to use a browser to connect to sites hosted on AWS
  • to connect to AWS EC2 VMs using SSH (an alternative will connection method can be provided)

To take full advantage of this training, participants :

  • should be at ease working at the command line
  • have basic notions of Linux processes
  • have basic notions of container engines such as Docker
  • Be able to use an SSH client such as openssh on Linux, macOS, WSL or Putty on Windows

The training will be entirely in English. Therefore, participants must have a sufficient level in English to understand the presentations and other materials.

Assessment

At the beginning of the training, a self-assessment is carried out to evaluate the level and expectations of each participant. In this way we can best organize the different working groups.
Afterwards, the trainer conducts an ongoing evaluation using the practical exercises.
At the end of the training, each participant's progress and achievements are self-evaluated. The trainer provides each participant with an evaluation, as well as areas for improvement.

Agenda

Proposed as a 4 day training, this may be extended to 5 days to have more time to complete the hands-on labs and thus better assimilate the concepts & practical skills.
