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.

Running your code editor in a remote container and accessing it via HTTPS

In this section, we will show how you can use Visual Studio Code to enable remote development inside a container. This is interesting when you are limited in what you can run on your workstation. Let's follow these steps:

  1. Download and extract the latest version of code-server. You can find out the URL by navigating to https://github.com/cdr/code-server/releases/latest. At the time of writing, it is 1.1156-vsc1.33.1:
$ VERSION=<version>
$ wget https://github.com/cdr/code-server/releases/download/${VERSION}/code-server${VERSION}-linux-x64.tar.gz
$ tar -xvzf code-server${VERSION}-linux-x64.tar.gz

Make sure to replace <version> with your specific version.

  1. Navigate to the folder with the extracted binary, make it executable, and start it:
$ cd code-server${VERSION}-linux-x64
$ chmod...
