All Tini does is spawn a +single child (Tini is meant to be run in a container), and wait for it +to exit all the while reaping zombies and performing signal forwarding. + +Using Tini has several benefits: + +- It protects you from software that accidentally creates zombie + processes, which can (over time!) starve your entire system for PIDs + (and make it unusable). +- It ensures that the default signal handlers work for the software you + run in your Docker image. For example, with Tini, SIGTERM properly + terminates your process even if you didn't explicitly install a signal + handler for it. +- It does so completely transparently! Docker images that work without + Tini will work with Tini without any changes. |
