Installing Docker and downloading the ASPECT image#

Docker is a lightweight virtualization software that allows to ship applications with all their dependencies in a simple way. It is outside of the scope of this manual to explain all possible applications of Docker, and we refer to the introduction (https://www.docker.com/what-docker) and installation and quickstart guides (https://www.docker.com/products/docker) on the Docker website for more detailed descriptions of how to set up and use the docker engine. More importantly Docker provides a marketplace for exchanging prepared docker images (called Docker Hub). After setting up the docker engine, downloading a precompiled ASPECT image from Docker Hub is as simple as typing in a terminal:

docker pull geodynamics/aspect

Note that the transfer size of the compressed image containing ASPECT and all its dependencies is about 900 MB. When extracted the image requires about 3.2 GB of disk space.
