Kubernetes

Kubernetes is clearly the technology of choice for deploying Cloud Native applications either to the Cloud or for on-premise deployments.
Give your Administration, Operations and Developer teams the training they need to master this powerful Open Source technology.

Adopting Kubernetes will empower your teams to deploy applications to take advantage of

  • savings in capital and operational expenditure
  • efficiencies of container & orchestration
  • reduced time to market for your services
  • minimal downtime, ease of upgrade of applications

We have a selection of Kubernetes trainings covering Adminstrator or Developer tasks, certification exam preparation and more advanced “Kubernetes in Production” trainings.

Below we detail our standard training offerings – these are regular trainings which have been run many times but which can be adapted to specific customer requirements

Container Orchestration Technologies

  • Kubernetes Administration, 4 days BELOW
  • Kubernetes Developer, 3 days BELOW
  • CNCF Kubernetes CKA exam preparation, 2 days BELOW
  • CNCF Kubernetes CKAD exam preparation, 2 days BELOW
  • Kubernetes in Production (coming soon) BELOW

Kubernetes Administrator Training

This training is typically delivered over 4 days, but can be adapted to your needs. This training covers the skills needed for basic Kubernetes administration and provides also a general preparation for the CKA exam – Note that an exam focused training is also available

Synopsis

This training is proposed here as a 4-day training providing a comprehension introduction to Kubernetes. This can be delivered as 4 full-days or 8 half-days as desired. The training can also be shortened or extended depending upon particular customer interests and needs.

The training covers Kubenetes the Container Orchestrator – an Open Source project created by Google and donated to the CNCF (Cloud Native Computing Foundation) – which has been extremely popular since it’s introduction in 2014 and continues to revolutionize the IT industry.

Objectives

  • Learn the principles of container orchestration – why this is needed and how Kubernetes addresses those needs.
  • Master the basics of Kubernetes
  • Learn how to design for and deploy applications to Kubernetes

Description

The course is highly interactive through presentation, demos, quizzes, hands-on labs and troubleshooting challenges. The concepts of container orchestration and their implementation in Kubernetes are covered. Students will learn why Kubernetes uses Pods with containers and how to design and deploy applications. Many practical concepts such as storage, exposing applications by Services or by Ingress Controllers will be covered. Time will be spent equally on presentation/demos and hands-on lab exercises.

Students will learn about the principles and resources of Kubernetes which make it particularly adapted to running many applications distributed across the cluster at scale with reliability – bringing such complex activities within the reach of all IT organizations.

Students will be provided with extensive hands-on labs and many resources available to them after the course. The course is a perfect preparation to be able to operate or develop for Kubernetes and take the appropriate CNCF certification exams if desired.

The extra troubleshooting exercises have proved particularly useful to prepare students for taking the exams, or for working with Kubernetes
