I’ve been using Mutagen with Docker for about 3-4 months to work around an (at the time) performance problem with bound volumes. I understand the new experimental FS option in Docker might solve this, but I haven’t tested or migrated my setup yet. Basically, I’m working on a bare metal kernel in C/C++ on ARM, which only has tooling on Windows or Linux. As I work on a Mac system, I setup a Docker container that makes this trivial for me, including GDB debugging of QEMU on the host machine. Mutagen was easy to get going, well documented, and has worked perfectly for this. I’m able to make my edits in my Mac IDE, then literally by the time I’ve switched to compilation, the edits are synced to the container, and vice-versa for the build product. Prior to Mutagen, I was getting 8-10x longer build times since Docker file synchronization was slowing things down. Mutagen syncs slower than Docker, but faster than I can work, so all is well.
