Docker

First install DockerDesktop and docker-compose:

• https://www.docker.com/products/docker-desktop/
• https://docs.docker.com/compose/install/

Then you can export a path to mount as a volume and spin up the containers:

export DATA_DIR = /some/path/to/mount
docker-compose --file software/container/docker-compose.yml up

Mosquitto

mosquitto_sub -h localhost -t '#' -p 1883
mosquitto_pub -h localhost -p 1883 -t '/' -m $(date --utc +%s)

There is also a very usefuly tool to debug MQTT: MQTT Explorer, that is also available at mqtt-explorer.com.
