Overview of this book

Containers enable you to package an application with all the components it needs, such as libraries and other dependencies, and ship it as one package. Docker containers have revolutionized the software supply chain in both small and large enterprises. Starting with an introduction to Docker fundamentals and setting up an environment to work with it, you’ll delve into concepts such as Docker containers, Docker images, and Docker Compose. As you progress, the book will help you explore deployment, orchestration, networking, and security. Finally, you’ll get to grips with Docker functionalities on public clouds such as Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP), and learn about Docker Enterprise Edition features. Additionally, you’ll also discover the benefits of increased security with the use of containers. By the end of this Docker book, you’ll be able to build, ship, and run a containerized, highly distributed application on Docker Swarm or Kubernetes, running on-premises or in the cloud.

Questions

Please try to answer the following questions to assess your learning progress:

  1. How would you create a named data volume with a name—for example, my-products—using the default driver?
  2. How would you run a container using the alpine image and mount the my-products volume in read-only mode into the /data container folder?
  3. How would you locate the folder that is associated with the my-products volume and navigate to it? Also, how will you create a file, sample.txt, with some content?
  4. How would you run another alpine container in to which you mount the my-products volume to the /app-data folder, in read/write mode? Inside this container, navigate to the /app-data folder and create a hello.txt file with some content.
