Docker Intro

Linux container technology and Docker fundamentals.

Course Description

Linux containers are changing the way companies think about service development and deployment. Containers play a vital role in the modern data-center, and Docker is leading the way. This course covers all 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.

Training Objectives

At the end of the training participants:

  • Understand what application containers are and which Linux kernel features, such as namespaces, make them possible.
  • Know the role of container runtimes and the place of Docker in the container ecosystem.
  • Start, stop, list and inspect containers and execute commands inside them with the docker CLI.
  • Manage the filesystem of containers, including the overlay filesystem and Docker volumes for persistent data.
  • Create container images from running containers and build custom images with a Dockerfile.
  • Understand how containers are connected to the network and use host networking, shared network namespaces and published ports.
  • Understand the architecture of Docker, work with image registries and extract container logs for troubleshooting.

Target Audience

System administrators, developers and DevOps who want to understand and use Docker in cloud and data center environments.

Prerequisites

Proficiency with the Linux CLI. A broad understanding of Linux system administration.
