+#####################################
+License Analysis of Docker Containers
+#####################################
+
+Vagrantfile that includes tern + scancode for performing dynamic license analysis
+of docker containers. It takes either a Dockerfile or image name to analyse.
+
+
+*********
+Reasoning
+*********
+
+While there are tools supporting ONAP development that perform license analysis
+and produce SBoM, they do it via static static analysis. When base image
+introduces licensing issue we will have no way to know from those tools.
+Additionally, the tools performing those static analysis require special access
+rights which only few people have. This Vagrant box is meant to be run as close
+to Docker build as possible to give feedback directly to developers.
+
+It has been placed in a VM due to following reasons:
+
+- reproducibility
+- tern requires:
+
+    * access to /dev/fuse
+    * access to docker.sock
+
+Due to the above requirements, running in Docker would require:
+
+  * running container in --privileged mode
+  * passing host's /dev/fuse to the container
+  * passing host's docker.sock to the container
+
+Running it in VM creates new instances of both which should alleviate security
+issues that could be present when running on host/docker
+
+
+***************
+Getting started
+***************
+
+Prerequisites
+=============
+
+`Vagrant <https://www.vagrantup.com/downloads>`_
+
+
+Running
+=======
+
+Dockerfile analysis
+-------------------
+
+Substitute the DOCKER_FILE_ANALYSE value with location of the Dockerfile
+you want to analyse::
+
+  DOCKER_FILE_ANALYSE="/path/to/Dockerfile" vagrant up
+
+Please mind that the Docker on the VM needs to be able to download the base
+image for analysis to take place.
+
+Docker image analysis
+---------------------
+
+
+Substitute the DOCKER_IMAGE_ANALYSE value with your image of choice::
+
+  DOCKER_IMAGE_ANALYSE="debian:buster" vagrant up
+
+Please mind that the Docker on the VM needs to be able to download the image
+for analysis to take place.
+
+Gathering results
+=================
+
+::
+
+  vagrant ssh-config > ssh-config
+  scp -F ssh-config default:~/ternvenv/report-scancode.json report-scancode.json
+
