> Now every time a package in Alpine gets an update you have to update all 10 containers. Because you will have no way of knowing if that package impacts the security of the service running in that container.

That's pretty much the baseline when dealing with any software system, whether it's a bare metal install of a distro, a distro running on a VM, or software running in a container.

All it takes is inheriting the latest version of an image and running docker build prior to redeploying.

I mean, this stuff is handled automatically by any CI/CD pipeline.

If you don't carr about running reproducible containers you can also sh into a container and upgrade it yourself.

Do you also complain about package managers such as deb or rpm because most debian and redhat users run a bunch of software full of security holes?

Software updates is not a container issue. It is a software deployment issue. I mean, when you complain about keeping packages updated you are in fact complaining about the OS running on the base image.
