Raspberry Pi based Agent

The setup of an Raspberry Pi single-board computer is the easiest way to participate in a RIasC cloud of labs.

Requirements​

Installation​

  1. Request a token and hostname from the cluster admin.
    • Note them down. We will need it later.
    • Example:
      • TOKEN=K109b5813dd9a6944badc430e0e457179e4c83333f882a13ea7356134be77d3508b::server:e851c7e39f5fe771b8b9377c79eaff68
      • HOSTNAME=riasc-node-vtt
  2. Use your SD card imager tool of choice to write the image to a spare SD card.
    • If asked use the following link as a URL for downloading the image: https://rwth-aachen.sciebo.de/s/7RpsGEl7NEEsvf1/download?path=%2F&files=2021-09-22-riasc-raspios.zip
  3. Re-insert the SD card reader and open the boot partition of the SD card.
  4. Adjust the riasc.yaml file inside this partition:
    • Adjust the the settings hostname and ansible.variables.token with the values from step 1.
    • Relevant locations are marked with # changeme! inside the file.
  5. Insert the SD card in the Raspberry Pi and power it on.
  6. Wait until provisioning completes.
    • The first boot will take a while (> 10 minutes)
    • You can follow the process by attaching a screen to the Raspberry Pi
    • ..or run the following command after login via SSH: sudo journalctl -fu riasc-update
    • The Raspberry Pi will reboot several times during the process.
    • Once finished the the console should print RIasC update completed successfully!
  7. Verify that the node has been provisioned successfully:
    1. Login to the Raspberry Pi with the standard credentials via console:
    • User: pi
    • Password: raspberry
    • Login via SSH is also possible
    1. Check the status of the riasc-update service by running the following command: sudo systemctl status riasc-update
  8. Change the default password:
    • Run the passwd command and follow the instructions
