Heroku - Mongo Sync

This is a plugin for the Heroku command line, adding commands to sync your local and production mongo databases.

It was tested and should just work with Mongo HQ. If you host your mongo db somewhere else, just make sure you have access from your local machine.

About this fork

I've fixed a bug when running 1.9.2, "can't modify frozen string". While figuering out how to fix it, I created a new gemset in rvm and built a Gemfile describing the gems needed. I replaced baconmocha with rspec and mocha, for no other reason that I struggled getting bacon to run (and I don't real care much about the test runner, I care about tests). All tests run >spec spec. Oh yeah, I've added the mongodb default port in the tests.

Thanks to pedro for creating the plugin!


# From this ruby 1.9.2 fork
$ heroku plugins:install
# or from the pedro's original
$ heroku plugins:install


The plugin assumes your local mongo db is running on your localhost with the standard settings (port 27017, no auth). It will use a database named after the current Heroku app name.

You can change any of these defining the URL it should connect to, like:

export MONGO_URL = mongodb://user:pass@localhost:1234/db

For production, it will fetch the MONGO_URL from the Heroku app config vars.


Get a copy of your production database with:

$ heroku mongo:pull
Replacing the myapp db at localhost with
Syncing users (4)... done
Syncing permissions (4)... done
Syncing plans (17)... done

Update your production database with:

$ heroku mongo:push
Are you sure? (y/n) y
Syncing users (4)... done
Syncing permissions (4)... done
Syncing plans (17)... done

As usual, in case you're not inside the app checkout you can specify the app you want to pull/push to:

$ heroku mongo:pull --app myapp-staging

If you're inside a checkout with multiple apps deployed, you can also specify the one to pull/push to by the git remote:

$ heroku mongo:pull --remote staging
