Kubernetes for Programmers

Duration

2 days

Description

This comprehensive course provides a deep dive into Kubernetes, the leading container orchestration platform. It covers everything from the basics of Kubernetes and containerization to advanced topics such as application lifecycle management, networking, storage, scheduling, and security. The course also includes hands-on exercises with popular Kubernetes tools and integrations with CI/CD pipelines and public cloud. Whether you're a software developer, DevOps engineer, or IT professional, this course will equip you with the skills to effectively manage and scale applications using Kubernetes. The course is designed for professionals with a background in computer programming, and it's a great way to stay up-to-date with the latest trends in cloud computing and container orchestration.

Objectives

Understand the fundamentals of Kubernetes and container orchestration, including local Kubernetes platforms.
Set up a development environment using Docker Desktop and Visual Studio Code.
Gain proficiency in YAML, a human-readable data serialization language.
Learn Kubernetes core concepts and tools, and work with pods.
Master application lifecycle management in Kubernetes, including deployments and rollouts.
Understand Kubernetes networking and storage, including services, ingress, and volume types.
Learn about Kubernetes scheduling, jobs, and configuration management.
Familiarize with monitoring, logging, and security in Kubernetes, and integrate Kubernetes with CI/CD pipelines and public cloud.

Prerequisites

Basic programming and Linux command-line experience. Prior experience with Docker is strongly suggested but not required.

Training Materials

All students receive comprehensive courseware covering all topics in the course. Courseware is distributed via GitHub in the form of documentation and extensive code samples. Students practice the topics covered through challenging hands-on lab exercises.

Software Requirements

Students will need a free, personal GitHub account to access the courseware. Student will need permission to install Docker Desktop (or MicroK8s), Kubectl, Visual Studio Code, and Visual Studio Code Extensions on their computers. As an alternative to Docker Desktop, the course can be taught with MicroK8s.
