Difficulty level: Very athletic
After creating a Kubernetes - cluster in the Great things with containers: Kubenetes cluster and NFS storage tutorial, I want to install a Kubernetes dashboard. This command contains everything I need for my project: x – + Terminal $ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.2.0/aio/deploy/recommended.yaml Since the associated service is not accessible from the outside, the “.spec.type” node must still be changed. -

After creating a Kubernetes cluster in the Great things with containers: Kubenetes cluster and NFS storage tutorial, I would now like to be able to address these machines via Ansible. A new key is required for this: x – + Terminal $ ssh-keygen -b 4096 The new public key added to the “/home/pi/.ssh/authorized_keys” file of all servers (Server 1, Server 2 and Server 3). -

Difficulty level: It may take a little longer
If you want to shut down a Raspberry above a certain temperature, then you are in the right place. I have a script that checks the CPU temperature via crontab: #!/bin/sh # This script reads the Broadcom SoC temperature value and shuts down if it # exceeds a particular value. # 80ºC is the maximum allowed for a Raspberry Pi. # Get the reading from the sensor and strip the non-number parts SENSOR="`/opt/vc/bin/vcgencmd measure_temp | cut -d "=" -f2 | cut -d "'" -f1`" # -gt only deals with whole numbers, so round it. -
Difficulty level: It may take a little longerSmartTVs can be ticking time bombs. Often, the TV operating systems contain serious gaps or are not kept up to date. A good solution can be a standalone MediaPC operating system. LibreElec runs on the weakest Raspberry and can be controlled with the TV’s remote. LibreElec is more customizable than a SmartTv operating system and offers a variety of apps/modules. All you need is a RaspberryZeroW and a blank SD card.

Difficulty level: Really challenging
How to create a build monitor for Bamboo, Jenkins or Gitlab? I’ll figure it out by tonight! I have already written a similar Tutorial for Gitlab Issue Boards. The basis for this tutorial is the Raspberry imager and the “Raspberry Pi OS Lite” operating system. After the OS installation, the SD card can be inserted into the Raspberry. In my case this is a Raspberry Pi Zero. Step 1: Install Matchbox/Window Manager To run a Raspberry in kiosk mode, a window manager and a browser are needed.
