+An Interlink plugin is the last component of the InterLink chain (https://intertwin-eu.github.io/interLink/docs/intro/). 
 In particular, the docker plugin is responsible for executing the requests coming from the InterLink server, i.e. the requests to create, delete, logs and status of a POD, as docker containers.
 There are two main versions of the plugin that correspond with two different branches of the repository: the main and the 2-light-version-no-gpu.
 The main version of the plugin supports the creation of docker containers with GPU support, while the 2-light-version-no-gpu does not support GPU. In the first case, to build the binary executable, the following command should be used:
