Docker Compose slow on Docker for Mac and public wifi


On a recent visit to a Caffé Nero coffee shop, docker-compose commands were running extremely slowly. After an hour or so of restarting Docker, my Mac, and switching back an forth between Docker for Mac and Docker Machine, I just gave up and headed home, pinning the issue on the then-still-beta Docker for Mac.

Today I encountered the same problem, in a different Caffé Nero and on a stable version of Docker for Mac. It couldn’t be just a coincidence. A quick search brought me to this GitHub issue, and in particular this answer:

Hi guys localunixsocket to etc/hosts solved the issue for me

And sure enough, updating /etc/hosts to include localunixsocket fixed the issue immediately.

Your thoughts? I'd love to hear them. Please get in contact.
