Hello.

When running docker-compose up I get the following error message :

## Your distribution, identified as "bionic", is not currently supported, please contact NodeSource at https://github.com/nodesource/distributions/issues if you think this is incorrect or would like your distribution to be considered for support

It works with the older version of ubuntu. Change FROM ubuntu:latest in Dockerfile to FROM ubuntu:xenial.
