There are no ports exposed outside the Docker Networks. In this configuration, the Docker Containers involved remain as secure as the applications running within the containers. This is achieved by telling Docker to give a network interface to the Application UI Container that also exists in the network for Application A. However, when Application B needs to talk to Application A, then the two networks must be linked together. For example, consider the following system:īy separating each into its own Docker Network, the systems remain isolated from each other.
Docker Compose makes it very easy to create Docker Networks and link them together – to mimic production environments where each service is isolated in its own network and only interacts via defined interfaces. However, like with any technology, one must know how to be secure when using it.īy default, Docker interacts with other Docker Containers via the Docker Network. It’s a great way to ship a reliable software environment between systems or even to customers. It is useful for creating identical environments and sharing them between development, testing, production, and others.
Docker is an awesome technology, and it’s prevalent in nearly every software developer’s workflow.
