This is the second anti-Docker (by extension, anti-container) post I've seen this morning (this first was on Medium, no surprise). The OP's lack of familiarity with Docker, and desire to re-invent the wheel into a different shape, is not anyone else's problem but that of the OP. There is a reason that the Docker-on-macOS or -Ubuntu monoculture exists: it works (darwin-arm64 aside) without a significant amount of effort, and is generally well-supported by the larger OSS community. Personally, I'd love to find a batteries-included FreeBSD distribution that is as simple to install as Ubuntu. Not everyone is a true believer, so the barriers to entry should be minimal.
