Welches sind die besten Docker Container?

Docker is becoming increasingly popular. Applications are executed in a Docker container in order to "dock" them in any environment. This primarily involves the distribution of applications and services as part of deployment. This makes it easy to test a colleague's new application on your own machine, for example. With Docker, all dependencies of an application can be mapped in a Docker image. A Docker image is provided to give the application with all its dependencies to a colleague. The Docker container can be easily executed on the local computer. Instead of the hypervisor, a Docker container requires the so-called Docker Engine. This ensures access to the kernel of the host operating system. This means that even large applications can be started or stopped quickly, as the entire operating system does not have to be booted at startup. However, this requires the Docker Engine to be installed on the computer.

Container technology was originally developed to be able to run multiple virtual operating systems in isolated environments on the same kernel - in the sense of multiple processes running as full system containers. The Docker container platform, on the other hand, focuses on so-called application containers, in which each application runs as a single process in its own virtual environment. Complex applications are implemented with Docker as multi-container apps. If the Docker engine is the heart of the container platform, then Docker Hub is the soul of the open source project. The community meets in Docker Hub and users can find everything they need for the Docker installation in the cloud-based registry. Other offerings include Docker Cloud and Docker Store.
