Memory requirements: To run a complete application with Docker images, you should consider dedicating at least 6 GB of memory to the Docker environment. As a consequence, it is recommended to have a laptop with at least 16 GB of RAM.

You can then check your Docker installation with the following commands (you may need to use sudo on Linux).

$ docker version
Docker version 20.10.15 [or above]
