Because I don't need it. I learned how to manage Linux servers in the early 2000s and that works for me. Docker on a VPS is ridiculous and wherever you find Docker you inevitably end up with Kubernetes. If I had a massive fleet of servers to manage I just might need containers but I'd probably try Chef or Puppet first. Docker is like React - designed for the needs of a global-scale internet company but now sprinkled mindlessly over sites which would be well served by a static site generator.
