Docker is a containerization platform. Docker is used to running lightweight containers on your computer.
Synology NAS has official support for Docker. Docker can be an alternative to virtual machines. If you don’t have enough memory to run virtual machines on your Synology NAS, you can run Docker containers instead. Docker containers require a very little amount of memory and system resources to run.
