Description-en: wrapper script which proxies signals to a child
dumb-init is a simple process supervisor and init system designed to run
as PID 1 inside minimal container environments (such as Docker).
.
Lightweight containers have popularized the idea of running a single
process or service without normal init systems like systemd or sysvinit.
However, omitting an init system often leads to incorrect handling of
processes and signals, and can result in problems such as containers
which can't be gracefully stopped, or leaking containers which should
have been destroyed.
.
dumb-init acts as PID 1 and immediately spawns your command as a child
process, taking care to properly handle and forward signals as they are
received.
