Dear all, I’m planning to setup Docker on the EPC1522. But I wonder how to disable the build in Node-Red and InfluxDB? Kind regards, Wilco

Hi meewis, there is no easy way to disable the pre-installed Node-RED or InfluxDB. Is it necessary in regards of performance? - I don’t think an empty Node-RED or InfluxDB will have impacts. This might not be new to you, but Docker-Portainer can be installed via the PLCnext Store as an App: https://www.plcnextstore.com/977 You just have to register your EPC using your UUID number printed on your device.

with update-rc.d you can deactivate the autostart from the tools.

Hello Jan and others, With the tip from Jan I managed to disable the build-in Node-Red and InfluxDB. I used the following commands: #su #update-rc.d node-red-init.sh disable #update-rc.d influxdb-init.sh disable #update-rc.d kapacitor-init.sh disable #update-rc.d chronograf-init.sh disable #update-rc.d telegraf-init.sh disable #reboot I installed the Balena-Engine by a download of balenaEngine-DockerForIOT from the plcNextStore and installed that. Moved the Balena var/lib directory to the SSD and installed Node-Red, Mosquitto, InfluxDB2 and Grafana. It all works and I’m happy. :smiley: Kind regars, Wilco
