How to use SIGKILL to rapidly terminate containers in Kubernetes
Originating from Linux, which uses a Unix operating system, SIGKILL is a common command that developers use to terminate absolutely any process. Most commonly, if anything needs to be shut down immediately as it's causing damage to the system itself, then SIGKILL is the go-to signal to use.
Alongside Linux, SIGKILL has also found itself into any developer platform that manages container systems, with the most popular example of this being Kubernetes. As one of the most drastic signals that you can execute, SIGKILL will instantly terminate a process, without giving the system the opportunity to block or ignore the signal. With this, absolutely any processes that are connected to the process you’ve killed will also terminate.
