With Dockerfiles, we can describe the way in which to build a Plugin, that will then be available on the platform.

This Dockerfiles must be placed inside a directory called task. There a currently no limits in what this Dockerfiles should contain, nevertheless they should be as independent and minimal as possible.

Also, the task directory must contain every file necessary to build the Docker image. Once built, the image will then be uploaded to Docker Hub by the CI system integrated in GitHub, so no further steps need to be taken by the developer apart from testing locally and in a development branch before merging into master.

There are multiple examples within Plugins that are built this way, checkout out Node-RED Plugin and TTN Stack Plugin.
