Question 1

What Kubernetes training courses are available at JBI Training?

Accepted Answer

JBI Training offers four Kubernetes courses covering different roles and experience levels. The Kubernetes course is a three-day introduction suitable for those new to container orchestration. Kubernetes for Developers is a three-day course focused on building, deploying, and managing applications in Kubernetes environments. Kubernetes for Administrators is a three-day course covering cluster management, networking, storage, security, and operations. Kubernetes Beyond the Basics is a two-day course for those who already have working Kubernetes knowledge and want to extend their skills. All courses are available as scheduled classroom sessions in London, as live online instructor-led training, or as customised onsite programmes for teams.

Question 2

What is Kubernetes and why is it widely used in modern software engineering?

Accepted Answer

Kubernetes (commonly abbreviated as K8s) is an open-source container orchestration platform originally developed by Google and now maintained by the Cloud Native Computing Foundation (CNCF). It automates the deployment, scaling, load balancing, self-healing, and management of containerised applications across clusters of machines. Kubernetes is widely used because it solves the core challenges of running containers reliably at scale — particularly across cloud environments — and has become the de facto standard for production container workloads. It is supported natively by all major cloud providers including AWS (EKS), Google Cloud (GKE), and Microsoft Azure (AKS).

Question 3

What is the difference between the Kubernetes for Developers and Kubernetes for Administrators courses?

Accepted Answer

The Kubernetes for Developers course focuses on the skills and knowledge that application developers need to build, package, deploy, and manage applications running in Kubernetes — including working with Pods, Deployments, Services, ConfigMaps, Secrets, and persistent storage from a developer perspective. The Kubernetes for Administrators course focuses on the operational and infrastructure skills needed to set up, manage, secure, and maintain Kubernetes clusters — including cluster architecture, networking, RBAC, monitoring, upgrades, and troubleshooting. Both courses are three days and are designed for professionals with different roles and responsibilities within a Kubernetes environment.

Question 4

What experience is needed to attend a Kubernetes training course?

Accepted Answer

For the introductory Kubernetes course and the role-specific Developer and Administrator courses, delegates should have a basic understanding of Linux command-line usage and a general awareness of containerisation concepts. Prior experience with Docker or another container runtime is helpful but not always required. For the Kubernetes Beyond the Basics course, delegates should have hands-on working experience with Kubernetes — equivalent to having completed one of the introductory courses or having used Kubernetes in a professional environment.

Question 5

What is the relationship between Docker and Kubernetes?

Accepted Answer

Docker is a containerisation platform used to build and package applications into portable container images. Kubernetes is a container orchestration platform used to run, scale, and manage those containers across a cluster of machines in production. In a typical workflow, a developer uses Docker to build and test a container image locally, and Kubernetes is then used to deploy and manage that container at scale across a production environment. While Kubernetes originally relied on Docker as its container runtime, it now supports multiple runtimes through the Container Runtime Interface (CRI), including containerd and CRI-O. JBI's Docker course is a natural precursor to Kubernetes training for those new to containerisation.

Question 6

What does the Kubernetes Beyond the Basics course cover?

Accepted Answer

The Kubernetes Beyond the Basics course is a two-day programme designed for professionals who already have working Kubernetes knowledge and want to deepen their expertise. It covers advanced topics that go beyond standard introductory content, including advanced scheduling and resource management, custom resource definitions (CRDs) and operators, advanced networking patterns, Kubernetes security hardening, service mesh concepts, extending Kubernetes with admission controllers, and strategies for operating Kubernetes effectively at scale in production environments.

Question 7

Is Kubernetes training available for corporate engineering teams?

Accepted Answer

Yes. All Kubernetes courses at JBI can be delivered as customised onsite or online programmes for corporate engineering and DevOps teams. Content and exercises can be tailored to the team's cloud provider, existing infrastructure, specific use cases, and Kubernetes maturity level. For example, a team running workloads on Azure Kubernetes Service (AKS) can receive training focused on that environment, or a team migrating from virtual machines to containers can receive a programme that addresses the migration journey as well as Kubernetes fundamentals. JBI has delivered Kubernetes and DevOps training for engineering teams at organisations including the BBC, NHS, Cisco, Sky, and Capita.

Question 8

Does Kubernetes training cover cloud-managed Kubernetes services such as AKS, EKS, and GKE?

Accepted Answer

Yes. JBI's Kubernetes courses address the major cloud-managed Kubernetes services — including Azure Kubernetes Service (AKS), Amazon Elastic Kubernetes Service (EKS), and Google Kubernetes Engine (GKE) — alongside core Kubernetes concepts that apply across all environments. Customised corporate programmes can be focused specifically on the cloud provider and managed Kubernetes service that the team uses in practice, ensuring the training is directly applicable to the delegates' working environment.

Question 9

What is Kubernetes RBAC and is it covered in the training?

Accepted Answer

RBAC stands for Role-Based Access Control and is Kubernetes' built-in mechanism for controlling who can perform which actions on which resources within a cluster. It allows administrators to define roles with specific permissions — such as the ability to read Pods in a particular namespace but not delete them — and bind those roles to users or service accounts. RBAC is a critical security topic for any organisation running Kubernetes in production. It is covered in the Kubernetes for Administrators course and in the Kubernetes Beyond the Basics course, where security hardening and access control are addressed in depth.

Question 10

Are Kubernetes courses kept up to date with the latest Kubernetes releases?

Accepted Answer

Yes. Kubernetes follows a regular release cycle and JBI's training content is continuously reviewed and updated to reflect the latest stable Kubernetes version, deprecated APIs, new features, and evolving best practices from the Cloud Native Computing Foundation (CNCF) ecosystem. This includes updates to tooling such as kubectl, Helm, and monitoring stacks, as well as developments in the broader cloud-native landscape. Delegates learn skills that are current and applicable to the Kubernetes versions and practices used in production environments today.
