Before the introduction of the concept of the user-defined network, container linking was predominantly used for inter-container discovery and communication. That is, cooperating containers can be linked together to offer complex and business-aware services. The linked containers have a kind of source-recipient relationship, wherein the source container gets linked to the recipient container, and the recipient securely receives a variety of information from the source container. However, the source container will know nothing about the recipients to which it is linked. Another noteworthy feature of linking containers in a secured setup is that the linked containers can communicate using secure tunnels without exposing the ports used for the setup to the external world. Though you will find lots of deployments that use container-linking techniques, they are cumbersome and time-consuming to configure...

Overview of this book
Docker is an open source containerization engine that offers a simple and faster way for developing and running software. Docker containers wrap software in a complete filesystem that contains everything it needs to run, enabling any application to be run anywhere – this flexibily and portabily means that you can run apps in the cloud, on virtual machines, or on dedicated servers.
This book will give you a tour of the new features of Docker and help you get started with Docker by building and deploying a simple application. It will walk you through the commands required to manage Docker images and containers. You’ll be shown how to download new images, run containers, list the containers running on the Docker host, and kill them.
You’ll learn how to leverage Docker’s volumes feature to share data between the Docker host and its containers – this data management feature is also useful for persistent data. This book also covers how to orchestrate containers using Docker compose, debug containers, and secure containers using the AppArmor and SELinux security modules.
