What do you mean? I containerize my tools, and write a docker file to install everything. The dockerfile is just something like:

FROM ubuntu:22.04

RUN apt-get update &&
apt-get install -y helm pluto kubeval etc

How is that gross?

Generally, schools are a public space (unless you’re in private school). You have no right to privacy in public, nor do you have copyright on the photo. You can request they remove it here: https://help.instagram.com/contact/504521742987441?helpref=page_content but there is a good chance they won’t.

Edit: you live in Italy which has a specific law that photos of children cannot be published w/o permission. Just mention that and they’ll likely remove it.
