There is a middle ground. At sourcehut we don't use Docker, but we do use CI/CD and automate deployments. We have something like 12 dedicated hosts colocated in a local datacenter and we use virt-manager to host virtual machines - basically self-hosted VPS lite. It's a lot simpler and more robust, and easier to keep everything up to date. Fewer moving parts == more reliable software.
