How to install Cygnus correctly?
Tried Cygnus Docker installation (https://fiware-cygnus.readthedocs.io/en/latest/cygnus-common/installationandadministrationguide/installwith_docker/index.html):
docker pull fiware/cygnus-common docker run cygnus-common
Second one does not work. Tried docker run -p 5050:5050 -p 8081:8081 fiware/cygnus-common
curl http://localhost:5050/v1/version produces error. What might be the problem?
