How to prevent RethinkDB from creating test database

When you launch a rethinkdb instance, it will automatically create a database called 'test'. When you run multiple instances and cluster them using rethinkdb proxy this leads to the issue:

Database name conflict: test is the name of more than one database

If you try to delete the databases i.e using

r.dbDrop('test').run(conn, function(result) {
   console.log(result) // Will result in error
});

This will produce the following error:

ReqlOpFailedError: Database 'test' is ambiguous; there are multiple databases with that name in r.dbDrop("test")

So how to prevent RethinkDB from creating the 'test' database automatically? Or how to remove a database if you run into name conflict?

Solution

  • If you use rethinkdb create to create a data directory, no test database will be created.

    For example, if rethinkdb_data doesn't exist, this will create it with no test database:

    rethinkdb create
rethinkdb

    This will do the same, but uses -d to specify the location of the data directory:

    rethinkdb create -d /var/lib/rethinkdb/data
rethinkdb -d /var/lib/rethinkdb/data
