We used native MacOS processes and it worked out fine. In practice I don't recall any bugs due to different behavior between our dev environment (MacOS) and our production environment (Linux) and we saved a ton of time during development. Docker just wasn't worth it. This worked for us because our app didn't depend on any platform specific behavior.

Of course, if you are using Go or some other language with a fast, static cross-compilation step, you don't need to mount a source code volume into your container, you can just rebuild the whole container image or rebuild on the host and `docker cp` the new binary onto the target container.
