A Docker container packages applications in containers by virtualizing the operating system and dividing it into compartments to run applications. Powerful CPU-based devices can leverage virtualization to enable containers. Containers are easy to manage due to their atomic nature, enable more efficient use of system resources, faster delivery cycle and provide a nice layer of isolation. Microsoft...

In this case they would brick by losing most of their functionality and if restarted they would not boot anymore.

The problem, in this case, was that a misconfigured package was uploaded (raspi-copies-and-fi...
