Docker & Kubernetes

Course Overview

The Docker & Kubernetes course is designed to provide comprehensive knowledge and hands-on experience with containerization and orchestration technologies. Docker simplifies the process of packaging and deploying applications within containers, while Kubernetes manages the orchestration of these containers, ensuring scalability, resilience, and efficient resource utilization. This course covers the fundamentals, best practices, and practical applications of Docker and Kubernetes in modern software development and deployment.

Learn software skills with real experts, either in live classes with videos or without videos, whichever suits you best.

Description

The course begins with an introduction to Docker, explaining containerization concepts and the Docker ecosystem. Participants will learn how to create, manage, and deploy applications using Docker containers. Subsequently, the focus shifts to Kubernetes, covering container orchestration, scaling applications, managing deployments, and maintaining containerized environments. Hands-on labs and real-world scenarios will be explored to reinforce theoretical concepts and ensure practical proficiency.

Course Objectives

The primary objectives of the Docker & Kubernetes course are as follows:

Understanding Containerization: Provide a solid understanding of containerization concepts, Docker architecture, and container deployment.
Docker Basics: Familiarize participants with Docker commands, container creation, and Docker Compose for multi-container applications.
Container Orchestration: Introduce Kubernetes as a container orchestration platform and cover its key components and features.
Deployment and Scaling: Teach the deployment and scaling of applications using Kubernetes, ensuring optimal resource utilization.
Service Discovery and Load Balancing: Explore Kubernetes features for service discovery, load balancing, and managing application networking.
Configuration Management: Cover configuration management and the use of ConfigMaps and Secrets in Kubernetes.
Monitoring and Logging: Introduce monitoring and logging practices for containerized applications in Kubernetes environments.
Best Practices: Share best practices for designing, deploying, and managing applications in Docker and Kubernetes environments.
