The Complete Practical Docker Guide - Introduction to the Dockerfiles and Docker Compose

This chapter is a practical guide on creating custom Docker images and launching multiple services using Docker Compose. It starts with a pre-built project with two microservices, a front-end, and a back-end. The chapter covers dockerizing these microservices by creating Docker files and custom images. It then demonstrates launching these services simultaneously with Docker Compose. Finally, it adds a database and a graphical user interface to the existing services, launching all four services together. The chapter concludes with an invitation to a full-stack web development bootcamp.

What is the primary focus of this practical chapter?

• Creating custom Docker images and launching services

• Exploring Docker Swarm

• Learning about Docker networking

• Understanding Docker security

What is the initial setup provided for this chapter?

• A database and a user interface

• A cloud-based application

• A single monolithic application

• Two microservices with front-end and back-end

How many Docker files will be created for the microservices?

• None, pre-built images are used

• Three, including a shared configuration

• Two, one for each service

• One for both services

What additional services are added in the final section?

• A caching service and a message broker

• A database and its graphical user interface

• A logging service and a monitoring tool

• A load balancer and a reverse proxy

What is the final outcome of this chapter?

• Running four services simultaneously with Docker Compose

• Deploying a full-stack application on Kubernetes

• Launching a single service using Docker

• Creating a virtual machine for each service
