Docker image

For connecting to mongodb is possible to connect directly to the mongodb IP (to be specified in config-docker.yaml), if this is not possible then it's recommended to use docker-compose.

Docker compose

The docker compose is going to mount the volume resources/mongo as /data/db in the container. And mapping the mongodb container with port 27018 (to avoid conflicts with the default mongodb port).

The configuration file supercon2/config-docker.yaml is also mapped in the supercon2 container /opt/service/supercon2/config.yaml
