The configuration changes for the Discovery Service are now on the master branch of edx/configuration. There is no longer a need for a separate tag.

This partially reverts commit 9b3b738a.

Further profiling showed that LMS/Studio startup times about tripled
when we dropped Docker Sync in favor of Docker's built in cached volume
mount system (going from 7-8s to anywhere betwen 22-28s). So we're
rolling back the part of that commit that removed Docker Sync and the
recommendations in the README.

However, we still want to keep the minimum version at 17.05 Edge, for
image building purposes. We also want to clarify that we did try using
Docker's built in cached volume support, so that people don't waste
time trying it again until Docker really implements "delegated" mode.

That shouldn't be there!

The create_demo_data management command is now run for the E-Commerce Service. This creates a verified seat for the demo course, allowing developers to get started testing payments with minimal effort.

This will help get developers up and running with payments.

We don't have a simple way of managing groups at the moment. This is the next best alternative as managing groups/permissions is a bit beyond the scope of the current task.

- Remove sync provisioning to force upgrade.
- Add 17.05 as minimum version

See https://docs.docker.com/docker-for-mac/osxfs-caching/ for details.

This solves the same problem as #123 for Docker Sync. Docker doesn't support using a volume for a directory, and excluding certain subdirectories. Users will need to sync the entire directory, and re-install Node dependencies, until we find a more appropriate solution.

Devstack has been updated to use a smaller image for the Credentials Service. This image is built without Ansible.

I suspect these volumes retain outdated data between container creation instead of pulling the latest data from the image as intended. This results in services loading without assets.

Our usage of host volumes puts us in a weird position due to the fact that we want share code from the host while excluding certain directories, and pulling that information from the image itself. Docker doesn't seem to support such a configuration. We can resolve this issue by either rebuilding images completely with every change, using a separate container to build static assets, or explicitly sharing specific code directories rather than the entire directory.

7d21ef048f528bf98958904f6bb9f5c5fc253bf3  Updated CPU and memory recommendations

25a1102a74ffb4ac3d054ed5cac76a94fdeb9c7b  Added troubleshooting section to README

- Replaced calls to docker-sync-daemon with docker-sync, which is now daemon by default
- Moved from rsync strategy to native_osx, which is the new default
- Using :nocopy to avoid issues when syncing to named volumes

Fixes #110
