Syllabus

Chapter 1 - Introduction

An overview of the course

Find out what Docker can do for you, and we'll learn some of the basic jargon such as containers and images.

Introducing Docker

Images and Containers

Containers vs Virtual Machines

Installing Docker is much harder than actually using it. Here we guide you through the process.

Docker in Development and Production

Installing Docker Desktop

How to Check Docker is Working

You'll get a chance to deploy a real (but very small) Java application to a Tomcat based container.

Downloading Images

Running Containers

Port Mappings

Running on EC2 (optional demo)

You'll learn how to use DockerHub to find base images, and how to run containers from them

Docker Hub

Finding Base Images

Classic vs Modern Docker Commands

(Extra) For cygwin users: how to avoid TTY errors

Running Base Containers

Container Lifecycles

Errata - avoid using the :latest image

Practical: Running a Tomcat Container

Dockerfiles define images - you'll learn how to make your images in this section

Building images with "commit"

Dockerfiles

Copying files to images

Images Commands (CMD)

Copy vs Add

Labels vs MAINTAINER

We use Tomcat as an example application to deploy to a container

Setting up the IDE

How to Find Docker Base Images

How to Set the RUN Command in Docker

What Does the Docker EXPOSE Command Do?

Removing the Tomcat Default Applications

Installing a WAR file

Running a Spring Boot application in Docker is really easy!

Spring Boot Applications

You'll want to get your own DockerHub account to publish your images.

Pushing to DockerHub

You'll need to network containers together, especially if building a microservice architecture. It's easy and we learn about the Naming Service in Docker.

Containers and Services

Containers Names and DNS

Network Management

ERRATA: You will need some extra config in the next video...

Connecting to a Database Container

Network Topologies

Is Steve Jobs "notable or awesome"? (optional!)

Volumes enable you to persist some data from a container to disk

Introducing Volumes

Naming Volumes

Mount Points

This is an optional section. We use the fabric8 Docker Maven Plugin to integrate with a Java build process.

Fabric8 Docker Maven Plugin (DMP)

Build Problems with Maven Plugin?

Configuring DMP

Integrating with Maven Lifecycles

Integrating Pushes with Deploy

Jenkins

Starting up multiple containers for a system is tedious. Compose enables us to capture an entire system's architecture in a single text file.

Why Docker Compose?

Errata - use image mysql:5

Compose Files

Startup Order

Running docker-compose

Rolling out changes

To run serious production environments, you need an orchestration system. Kubernetes is the marker leader at the time of writing, but there is one built into Docker - Swarm.

Orchestration Systems

Introducing Swarm

Swarm Services

Warning - disable adblocker / ublock

Play with Docker

Monitoring Service Logs

Chapter 15 - Stacks

Managers vs Workers

Building a Stack
