I've been playing around with a few different self-hosted PaaS offerings (Exoframe, Caprover, Dokku et al), but nothing quite hit the mark. I ended up bootstrapping a small VM using cloud-init and found it worked seamlessly across all the major cloud providers with little to no vendor specific code - cloud-init is pretty neat! I ended up creating a Terraform module for deploying Docker containers + Docker Compose files and I'm pretty happy with how it turned out.
