Docker is a platform for developing, shipping and running applications inside of containers. A container is a lightweight, portable and self-sufficient environment that isolates applications to ensure that they run consistently throughout the development lifecycle. Docker containers are used by a wide variety of software developers because they can isolate their development environment from the host system, which prevents conflicts with other software or system configurations. What this means is we can work in an environment tailored specifically to Business Central Development that we know will be consistent.
