Ubuntu 22.04 LTS tini install not working
Opened this issue · 2 comments

I'm using Ubuntu 22.04 LTS as base image and running a couple child processes spawned by my entrypoint script in exec mode. I've installed tini via apt and the version is 0.19.0. However, even when I start tini as PID 1, it is not sending SIGTERM to my child processes as I expected. What am I missing here?

There’s a lot of processes in your hierarchy here. Tini sends SIGTERM to
its immediate child (or the whole process group if you use the -g flag).
You probably need your shell script to use “exec” to remove the shell
itself from this hierarchy and you should perhaps consider using a tool to
change the user that also uses exec (back when I was more involved in this
the tool to do that was gosu, not sudo, but perhaps that changed)
