Who knew Alpine was a really cool Docker host?
Alpine Linux is a really interesting, lightweight distribution of Linux that has a minimal foot print that belies some of the power capable in the distro. Not only is Docker easy to install on the platform, there are a lot of nice animations and quality of life features that makes what is normally the distro for building containers, a great distro to host those containers as well.
The latest version of Alpine features Linux kernel 6.12 which has a ton of nice features around the scheduler and a host of other features. While most of the features may not get used directly by a Docker host, the hosted containers will also leverage the underlying host OS kernel (a big difference between containers and VMs) so could also potentially benefit the application performance as well.
