We're also ignoring Kubernetes and are just using GitHub Actions, Docker Compose and SSH for our CI Deployments [1]. After a one-time setup on the Deployment Server, we can deploy new Apps with just a few GitHub Action Secrets, which then gets redeployed on every commit, including running any DB Migrations. We're currently using this to deploy and run over 50 .NET Apps across 3 Hetzner VMs.
