This Plugin is Depreciated

There is an official mongodb plugin for dokku hosted in the dokku org: https://github.com/dokku/dokku-mongo . I would recommend new users look there first. I will still maintain issues and pull requests here, but encourage users to consider migrating to the official plugin as it will get better support.

Simple usage

You need to have app running with the same name!

Create a new DB:

$ dokku mongodb:create foo            # Server side
$ ssh dokku@server mongodb:create foo # Client side

    {
        "_id" : ObjectId("524c90dc45addf0edad783a2"),
        "user" : "foo",
        "readOnly" : false,
        "pwd" : "825ec0deacccb3c6bb621d84153e5877"
    }

Now if you push your app again, you will have the following ENV variables:

MONGODB_DATABASE
MONGODB_HOST
MONGODB_PORT
MONGODB_USERNAME
MONGODB_PASSWORD
MONGO_URL
MONGO_URI

These can be found using:

dokku config appname

Persistence

The Mongo DB data is stored outside the container on the host at $DOKKU_ROOT/.mongodb/data. Inside the container, this location is bound to /tmp/mongo and will be there. Since the data is stored outside the container, it will persistent through container restarts, and also be available to future revisions of your container.

Backing up a database

mongodb:dump creates a backup of a whole database. The result can be optionally compressed in a gzipped tarball (tar.gz) by adding the -tar parameter after the database name. The dump is placed in the current directory and named <databasename>-<date and time>.
Example: dokku mongodb:dump api-production -tar

Restoring a database

mongodb:restore can be used to restore dump created with mongodb:dump (or mongodump which it uses internally). It can be used with a gzipped dump.
Example: dokku mongodb:restore api-production /path/to/dump/api-production-2015-03-09-16h54-43s.tar.gz

It can also be used with a database dumped to a folder (mongodb:dump without the -tarargument)
Example: dokku mongodb:restore api-production /path/to/dump/api-production-2015-03-09-16h54-43s/api-production/

This will drop the database and re-create it completely from the dump.
