Running thin-edge.io on Alpine Linux on a Raspberry Pi

1. Flash the latest Raspberry Pi alpine linux image to the SD CARD. See Alpine's Documentation for details

2. 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)

3. 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)

Set custom MQTT keep-alive value

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.

1. Stop all thin-edge.io related services

   tedge disconnect c8y
   systemctl stop tedge-agent

1. Append the ssh config to your machine's ssh config file

   The following snippet creates

   cat <<EOT >> ~/.ssh/config
   Host rpi5-d83addab8e9f
           User root
           PreferredAuthentications publickey

IdentityFile ~/.ssh/id_ed25519
