Eramba is an excellent open source Governance Risk and Compliance tool. Recently (10-SEP-2019), a new major release of the community version came out. Previously I used https://github.com/digitorus/eramba which was based on https://hub.docker.com/r/k0st/alpine-eramba/ to start eramba instances quickly with docker and docker-compose.
As I could not find an updated version of these for the new release I have made one. The repo for this, 2019 community version (specifically c2.4.1) can be found here: https://github.com/markz0r/eramba-community-docker
Follow the steps in README.md and you should be testing the new eramba in no time.
Mar, 2020: Updated for community edition 2.8.1
Thanks to the team at Eramba for making the tool available for all!
