Debugging has been an artistic component in the field of software engineering. All kinds of software building blocks individually, as well as collectively, need to go through a stream of deeper and decisive investigations by software development and testing professionals in order to ensure the security and safety of the resulting software applications. As Docker containers are said to be key runtime environments for next generation mission-critical software workloads, it is pertinent and paramount for containers, crafters, and composers to embark on the systematic and sagacious verification and validation of containers.

This chapter has been dedicatedly written to enable technical guys with all the right and relevant information to meticulously debug applications running inside containers and containers themselves. In this chapter, we will take a look at the theoretical aspects of process isolation for processes running as containers. A Docker container runs...
