Overview of this book

No doubt Docker Containers are the future of highly-scalable software systems and have cost and runtime efficient supporting infrastructure. But learning it might look complex as it comes with many technicalities. This is where The Docker Workshop will help you. Through this workshop, you’ll quickly learn how to work with containers and Docker with the help of practical activities.? The workshop starts with Docker containers, enabling you to understand how it works. You’ll run third party Docker images and also create your own images using Dockerfiles and multi-stage Dockerfiles. Next, you’ll create environments for Docker images, and expedite your deployment and testing process with Continuous Integration. Moving ahead, you’ll tap into interesting topics and learn how to implement production-ready environments using Docker Swarm. You’ll also apply best practices to secure Docker images and to ensure that production environments are running at maximum capacity. Towards the end, you’ll gather skills to successfully move Docker from development to testing, and then into production. While doing so, you’ll learn how to troubleshoot issues, clear up resource bottlenecks and optimize the performance of services. By the end of this workshop, you’ll be able to utilize Docker containers in real-world use cases.

Introduction

In the previous chapters, we discussed how to use Docker containers and Dockerfiles to create containerized applications. As apps get more complicated, the management of the containers and their configurations becomes more involved.

For example, imagine you are developing an online shop with frontend, backend, payment, and ordering microservices. Each microservice is implemented with the most appropriate programming language before being built, packaged, and configured. Thus, complex applications are designed to run in separate containers in the Docker ecosystem. Different containers require multiple Dockerfiles to define Docker images.

They also need complex commands to configure, run, and troubleshoot applications. All this can be achieved using Docker Compose, a tool for defining and managing applications in multiple containers. Complex applications such as YAML files can be configured and run with a single command in Docker Compose. It is suitable for various...
