If Patroni was started in a docker with pid=1 it will execute itself with the same arguments. The original process will take care about init process duties, i.e. handle sigchld and reap dead orphan processes. Also it will forward SIGINT, SIGHUP, SIGTERM and some other signals to the real Patroni process.
