About Kubernetes for beginner Training Course (LFS258) 

This Kubernetes for beginner and intermediate training will teach you how to use Kubernetes effectively, including how to deploy a containerized application and manipulate resources using the API.

This course is for anyone who wants to learn how to handle a containerized application infrastructure. This covers both current IT managers and those interested in pursuing a cloud career.

Skills obtained will significantly improve students’ ability to become qualified by preparing them for the Kubernetes Certified Administrator (CKA) Exam. 

Kubernetes for beginner – Administrator Training LAB INFO

Access to a Linux server or Linux desktop/laptop is required for hands-on lab experiments. You’ll also need access to a public cloud service or VirtualBox installed on your desktop. This course’s lab experiments have been reviewed in a GCP setting.

You should be able to complete the lab activities using the free tier or credits offered by a cloud service such as GCP or AWS. However, if you use more credits than the cloud service originally allotted, you can be charged.

WHAT YOU WILL LEARN

In this Kubernetes for beginner training, you will learn how to handle the application infrastructure using the container management software used by companies like Google. From network setup to enhancements to having clusters accessible via utilities, you’ll learn how to instal and configure a production-grade Kubernetes cluster.

The course also covers core concepts like pods, deployments, replicasets, and utilities, and will provide you with enough knowledge to get started with Kubernetes on your own.

What is Kubernetes?

Google created Kubernetes, a container orchestration framework, to manage docker containers. Using Kubernetes, you may manage hundreds or even thousands of containerized apps. It can also manage applications operating in diverse contexts, such as real computers, virtual machines, and even hybrid deployment settings.

Container orchestrator Kubernetes is one of the most often used solutions for this purpose. Load balancing, service discovery, and Role-Based Access Control are just a few of the edge features provided by Kubernetes (RBAC). Since its inception, Kubernetes has been referred to as “K8s” inside the industry.

Kubernetes is an extremely capable container orchestrator. Strong Stateful apps may be built simply by using these essential capabilities.

• To communicate amongst the components, pods and services are employed.
• Ingress is the method through which traffic is routed into the Kubernetes cluster.
• ConfigMap and Secrets are used for external configuration.
• A stateful set allows for data persistence through volumes.
• Pod blueprints aid in deployment replication.
• The Kubernetes Ecosystem boosts Productivity.
• Cloud Native and may be deployed across many clouds
• A decentralized application becomes considerably more stable.

Why did Kubernetes come into play?

Monolithic systems face a number of issues when it comes to hosting current software. It has been overtaken by the emergence of microservices architecture. Container technologies were ideal hosts for microservices because of their usage of microservices as the fundamental architecture.. For large-scale systems, scripting proved prohibitively difficult, especially when containers expanded to tens of thousands. It was virtually hard to build a consistent method for managing these microservices since everyone was writing their own scripts.

Container orchestration systems like Kubernetes were needed as a result of this.’

What are containers?

Containers are a kind of virtualization for operating systems. A single container is capable of running a microservice or process for a distinct application. The Container will include all executables, binary codes, libraries, and configuration data required. Containers are distinct from virtual machines (VMs). Each VM will have its own operating system, but containers do not. Consequently, containers are lightweight, and corporations use tens of thousands of containers. Docker is among the most popular container systems.

Advantages of containers

Reduced operating expenses

Packaging is lightweight. They use fewer system resources than conventional or hardware-based virtual machine environments. That’s because containers lack their own operating system.

Enhanced agility

Virtualization of container architecture enables the deployment of container-based applications on many operating systems and embedded systems.

Dependency problems no longer exist

Containers alleviate DevOps engineers from worrying about the dependency of their deployed apps. This provides a seamless transition from testing to production environments.

Greater productivity

Containers provide faster application deployment, patching, and scaling.

Better application development

Containers facilitate agile and DevOps initiatives to expedite the development, testing, and production cycles.

What benefits does a Kubernetes container orchestration tool provide?

1. High availability with no downtime.

If there are dozens of containers and anything goes wrong, scripts may be a terrifying experience. Troubleshooting problems becomes a monumental effort. Kubernetes prevents this from happening by making containers available. We do this by rapidly recreating a failing microservice.

2. Flexibility

Manually managing containers implies the software will never achieve its full potential. Kubernetes allows applications to function at full capacity, assuring peak performance. Users who access the application will benefit from faster performance.

3. Issues recovery

In a manually managed container system, triaging problems is analogous to looking for a book in a library without a classifying scheme. When a crisis hits a microservices system based on custom scripts, data is lost and services fail. After identifying the faulty container or configuration, the services must be restored to previous stable state settings, and data must be recovered from a backup. Kubernetes has a system for backing up data and restoring applications, ensuring that no data will be lost.
