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.

Preface

Docker Compose CLI

Docker Compose works with Docker Engine to create and manage multi-container applications. To interact with Docker Engine, Compose uses a CLI tool named docker-compose. On Mac and Windows systems, docker-compose is already a part of Docker Desktop. However, on Linux systems, you need to install the docker-compose CLI tool after installing Docker Engine. It is packaged into a single executable, and you can install it with the following commands on Linux systems.

Installing Docker Compose CLI in Linux

  1. Download the binary to /usr/local/bin with the following command in your Terminal:
    sudo curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
  2. Make the downloaded binary executable with the following command:
    sudo chmod +x /usr/local/bin/docker-compose
  3. Test the CLI and installation with the following command in the Terminal on all operating systems:
    docker...
