Error when running docker compose after set up script

[L. Meg Viar]

Hello! I'm working through the Quick Start directions from the Wiki on macOS with Big Sur version 11.2.3. I'm hoping to contribute to the codebase. Thanks for any suggestions on moving past these dev environment issues.

To start, I used homebrew to install docker-machine, dingy, and docker-compose. With a bit of finagling, I got the start up script to complete successfully. I used the default config files with no changes.

Now, when I run docker-compose up -d to try to start up Canvas, I'm running into errors (included at bottom of message).

The state of my docker machine:

NAME  ACTIVE   DRIVER  STATE  URL  SWARM   DOCKER  ERRORS
dinghy   *  virtualbox   Running tcp://192.168.99.100:2376 [none] Unknown   Unable to query docker version: Cannot connect to the docker engine endpoint

Full error(s) after running docker-compose build:

canvas-lms % docker-compose build

[Graham Ballantyne]

This isn't a Canvas error; it's an issue with your Docker setup. Specifically, the docker CLI can't connect to your docker-machine environment (hence the error "Unable to query docker version: Cannot connect to the docker engine endpoint).

If you're using dinghy, what does `dinghy status` say?

Apparently dinghy should be considered deprecated: https://twitter.com/ktgeek/status/1388669610547941382

Thanks for the quick response, Graham. The quick start script calls for dinghy, but looks like it could use some updates.

From dinghy status:

   VM: running
  NFS: stopped
 FSEV: stopped
  DNS: stopped
PROXY: stopped

After dinghy restart:

Starting the dinghy VM...
Starting NFS daemon, this will require sudo
Waiting for NFS daemon...
Mounting NFS /Users/crusher
Starting the FsEvents daemon
Starting DNS and HTTP proxy
docker: Cannot connect to the Docker daemon at tcp://192.168.99.100:2376. Is the docker daemon running?.
See 'docker run --help'.
   VM: running
  NFS: running
 FSEV: stopped
  DNS: stopped
PROXY: stopped
FsEvents failed to run
