The following instructions can be used to configure the wayvnc service so that it is compatible with the Cumulocity VNC viewer. These instructions will disable the authorization, however to keep the setup secure, it will only establish a listener on localhost (127.0.0.1) which will not allow other devices/services/applications in the network to connect to it.
Create systemd service template definition
cat <<EOT > /lib/systemd/system/[email protected]
[Unit]
Description=tedge-agent (device/%i//) is a thin-edge.io component to support operations.
After=syslog.target network.target mosquitto.service
On your computer, register the device in Cumulocity using the bulk registration api to create a username/password for the device.
c8y deviceregistration register-basic \
--id tedge-flows-demo2 \
--outputTemplate "std.manifestTomlEx({c8y:{username: output.username, password: output.password}}, '')"

Flash the latest Raspberry Pi alpine linux image to the SD CARD. See Alpine's Documentation for details
Remount the sd hard on your computer (as you'll be adding some additional files to it before the SD card is inserted into your Raspberry Pi)
Download the headless.apkovl.tar.gz file from the alpine-linux-headless-bootstrap repo and add it to the to the root folder of the mounted sd card (e.g. the FAT partition).
Note: You don't need to extract the headless.apkovl.tar.gz file, just place it there (there is a magic service which will execute it on boot)
Warning: If you run tedge reconnect c8y or tedge connect c8y, you will need to re-edit the c8y-bridge.conf file again (as it is auto generated). thin-edge.io will be added support to configure this value, but it hasn't been implemented yet, see issues/3153.
Stop all thin-edge.io related services
tedge disconnect c8y
systemctl stop tedge-agent
Append the ssh config to your machine's ssh config file
The following snippet creates
cat <<EOT >> ~/.ssh/config
Host rpi5-d83addab8e9f
