"Since I use Ubuntu in production, the Linux environment is closer to production than a Mac shell."

Docker

Oooh yes, I love Docker. Right now, I do most of my dev work outside Docker (because I don't want to rebuild the image every time I change a file..unless there's a way?). I do use Docker at intervals to make sure everything still works.

The shell being closer to production was more for familiarity sake. For me, I used to think I was going to be Mac for a long time because "Mac has a bash shell." Windows has a bash shell. In practice, I mostly use the ssh command! :)

Oh and the console window in Windows is now resizable! That drove me crazy.

I believe the current strategy is to have a container that contains your full build environment, push your source files in by mounting a folder, and then use file watchers to automatically rebuild/rerun.

How do you run Ubuntu binaries on Mac by using Docker? As far as I know it's not a virtualization layer.

Docker on Mac runs in a VM, either by one of the traditional virtualisation solutions (Virtualbox, VMWare, Parallels) or via xhyve. The VM acts as a Docker server, so the client on the mac side just passes options to the Docker VM. See: https://docs.docker.com/engine/installation/mac/

Docker now also has a native Mac client that doesn't require docker-machine

Thanks both! I believe the native Mac announcement is what put me off track.

Which gets pretty bad the moment you need to use shared volumes.

What does "native" mean in this context? The Mac client still runs containers in a Linux VM.
