Typically, available tools, methods, and approaches for meaningful troubleshooting of our containers and images has required installing additional packages in every container. This results in the following:

  • Requirements for connecting or attaching directly to the container, which is not always a piddling matter

  • Limitations on inspection of a single container at a time
