tini VS dualsensectl

yes busybox httpd or civetweb is even smaller, both around 300kb.

for tini you mean https://github.com/krallin/tini? how large is your final docker image, why not just alpine in that case which is musl+busybox

Tini, a useful process manager for containerized apps

Ah gotcha. I believe it can be baked into images as well, per the entrypoint example in the readme: https://github.com/krallin/tini

Not sure how this will fare IRL in k8s as I haven’t much experience there. It’s still silly that this is the default behavior where you need something like Tini, but I digress.

To be fair, even for running a single process the pitfalls are real. I've been seeing Tini[1] a lot for these situations.

I just read in the README that Tini is included by Docker since 1.13 if using --init flag.

The default init process used is the first docker-init executable found in the system path of the Docker daemon process. This docker-init binary, included in the default installation, is backed by tini.

AFAIK It's for the init process to reparent zombie processes. See TINI

The second easiest (and most common when your entry point is a bash script) is to use a fake init tool like tini

I've been using dualsensectl for a while, but I wanted to have the battery info for my controllers at a glance, instead of having to go to the terminal. So, with a bit of guidance from ChatGPT, I made a shell script that takes the battery level of a connected DualSense controller and outputs it on the tray via the xfce4-genmon plugin. It also powers off the controller when you click on the battery percentage number.

I found this but mentions nothing about the response time.

I downloaded this (https://github.com/nowrep/dualsensectl), extracted it to a folder and opened that folder in terminal.

Dualsensectl is a cli tool that controls ps5 controllers, you can use dualsensectl power-off to switch off the controller.
