• Loading Steam as an image in TAR format:

docker load -i steam.tar

• Check if the image is real:

docker image ls

• Create a simple docker-compose.yml:

version: '2'
SERVICES:
    Steam:
        image: steam:0.9
        volumes:
            - /var/steam/:/etc/runtime/share
        network_mode: "host"

• Installing Mosquitto to track the creation of entries.

sudo apt-get install mosquitto mosquitto-clients

• Starting the container for the first time.

docker-compose up

• Modification of the settings XML file (under/var/steam/Settings/).

 --> <SamplingThread-type>ADAS</SamplingThread-type>
 --> <ProcessingThread-type>MQTT</ProcessingThread-type>
	<!--ETHERCAT IP :127.0.0.1 / PORT 54011-->
	<!--MODBUS IP :192.168.0.12 / PORT 502-->
	<PhoenixIPAddress>192.168.214.152</PhoenixIPAddress>
	<PhoenixPort>54011</PhoenixPort>

	<MQTT_Topic>communicationAdapter/hf</MQTT_Topic>
	<MQTT_UserName>testName</MQTT_UserName>
	<MQTT_Password>testPassword</MQTT_Password>

• Start reading out entries posted in Mosquitto - please start in separate console:

paho_c_sub -t communicationAdapter/hf --connection tcp://localhost:1883

• Restarting the container

docker-compose up

After this, the console named above as “separate console” should output the JSON messages from Steam.
