Course Overview

This course combines the Docker and Kubernetes Administration courses. Participants will first understand the core features of Docker including: container creation and management, interacting with Docker hub, using Dockerfile to create and manage custom images, advanced Docker networking (how to safely expose container services to the world, and link containers), the use of Docker volumes to manage persistent data, and Docker Compose to build multi-container applications. Emphasis is placed on best practices and how to secure Docker installations and containers. The second part of the course introduces participants to the basic concepts and architecture of Kubernetes, its initial install and setup, Kubernetes Pods, deployments and services, persistent storage, networking, automating deployment, scaling and management of containerized applications, and finally it's logging and monitoring facilities.

Target audience: System administrators and Devops professionals who want to understand and use Docker and Kubernetes in enterprise and cloud environments.
