Why am I getting a 'Mounts denied' error?

ERROR: for workers  Cannot start service workers: Mounts denied: 
The paths /definitions and /files
are not shared from OS X and are not known to Docker.
You can configure shared paths from Docker -> Preferences... -> File Sharing.
See https://docs.docker.com/docker-for-mac/osxfs/#namespaces for more info.

ERROR: Encountered errors while bringing up the project.

macOS has limitations on which paths Docker is allowed to mount. To get around this, export the environment variable VOL_PREFIX to a path that Docker can mount, then try re-running docker-compose. Here's an example:

export VOL_PREFIX=~/packet_cafe_data
docker-compose up -d --build && docker-compose rm -f

Browsing to http://0.0.0.0/ shows "This page isn't working", how come?

It's likely that the lb (load balancer) container has become unhealthy. It can checked like this (scroll over to the status section and check the packet_cafe_lb_1 container's health):

$ docker ps

If it, or any of the containers, show as unhealthy then restart the service:

docker-compose restart
