Sync-endpoint-docker-swarm build failure

Hi John,

I just wanted to highlight this other post of mine about the same issue: Problems with login in to ODK-X Server web-ui. Incorrect username or password - #52 by JohnSnow

I couldn’t get sync-endpoint to work either, but ODK Aggregate seems to be a good alternative until the issues with sync-endpoint get resolved. I really wished it didn’t use Docker.
