# Launch a database in production and connect to it inside local nanobox app.

##### Create a boxfile with just a database and deploy

boxfile.yml
```yaml
run.config:
  # set your engine like normal
  engine: none

# define database desired in production
data.db:
  image: nanobox/postgresql:9.5

# not necessary for launching database only, but add for `deploy dry-run`
web.thing:
  start: sleep 1d
  local_only: true
```


##### Deploy your database with nanobox

```sh
nanobox remote add <myapp>
nanobox deploy
```

Depending on your setup, you can run `nanobox tunnel data.db` from your workstation and connect to it from within your local app.

Terminal 1
```sh
nanobox tunnel data.db
# listening on port 5432
```

Terminal 2
```sh
# Add database variables from dashboard
nanobox evar add local REMOTE_DB_NANOBOX_USER=nanobox,REMOTE_DB_NANOBOX_PASS=password
nanobox run
#...
# connect to your db
psql -h 192.168.99.1 -U nanobox -d gonano
# Password for user nanobox:
# psql (9.5.6)
# Type "help" for help.
#
# gonano=#
```

Alternatively, you can always download the linux version of the cli into your web container and `tunnel` from within that `nanobox run` and work in another terminal.

**Note:** *This was tested on linux with docker-machine (virtualbox), ymmv*
