You can use Dokku if you just need a CLI experience (it also has a paid web ui at https://pro.dokku.com). Works well enough for single servers, and you can use plugins to make it multi-server with Kubernetes or Nomad.
If you want to abstract all the multi-server setup and/or need something a bit more professional, I also work at a company called Porter (https://www.porter.run/), which handles the lifecycle of your app on top of the three major cloud providers. It provides a really nice experience on top of your own cloud, and abstracts the complexities of provisioning VPCs, networking, security, etc.
