What is the most minimalist Linux server distro?

I am asking for any distro that only has the bare-bones to be able to get a shell in the server and then just install the packages as we need for the application we want to run. Think of it like the RancherOS or CoreOS that only have the strictly necessary to run containers, but for bare metal or VPS servers wanting to run non dockerized workloads.

Current distros for server have too many packages you may need or not, and a lot of them you don’t need, thus they pose a security risk, because they are one more attack vector that can be exploited and put the system at risk.
