Expected output of "docker-compose ps" is different from actual.

[ntruncik]

In the "Lab Setup" section inside "Looking under the covers", the shown/expected output of "docker-compose ps" is different than actual/reality on the devbox.

We only have grafana, influxdb and pipeline running, there is no elasticsearch or prometheus.
