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 Terminal in a remote container and accessing it via HTTPS

There are situations where you need to access a remote server and only have the option to use a browser for that. Your laptop may be locked down by your employer so that you are not allowed to, for example, ssh into a server outside of the company's domain.

To test this scenario proceed as follows:

  1. Create a free account on Microsoft Azure, GCP, or AWS. Then, create a VM, preferably with Ubuntu 18.04 or higher as the operating system, to follow along more easily.
  2. Once your VM is ready, SSH into it. The command to do so should look similar to this:
$ ssh [email protected]
To get access, you may need to open port 22 for ingress first for the VM.

The user I have defined during the provisioning of the VM is gnschenker and the public IP address of my VM is 40.115.4.249.
