NodeJS and MongoDB app in Dokku with Digital Ocean

dokku-node-mongo.md

Steps:

1. Create Digital Ocean Droplet with Dokku v0.3.16 on 14.04 image

2. Login into the droplet and Update local settings.

   sh -c "echo 'LANG=en_US.UTF-8\nLC_ALL=en_US.UTF-8' > /etc/default/locale"
   reboot

3. Open http://<ip_address_of_droplet> to configure dokku settings.

4. Add dokku remote to your source code(from your development machine). In below code, app_name can be anything. It should be used when configure the database.

    ```shell
    git remote add dokku dokku@<ip_address_of_droplet>:<app_name>
    git push dokku master
    ```
   

5. Install MongoDB dokku plugins in Digital Ocean droplet.

    ```shell
    git clone https://github.com/jeffutter/dokku-mongodb-plugin.git /var/lib/dokku/plugins/mongodb
    dokku plugins-install    
    ```
   

6. Create database

    ```shell
        dokku mongodb:start
        dokku mongodb:create <app_name>
    ```
   

7. Change your MongoDB url to process.env.MONGO_URL and commit your source code. (You must push app again to take mongodb url) It will print the URL of the app. You can visit the app in browser.

    ```shell
    git push dokku master
    ```
   

8. You can also view mongodb config

    ```shell
    dokku config <app_name>
    ```
   

on 0.3.x

cd /var/lib/dokku/plugins git clone https://github.com/dokku/dokku-mongo.git mongo dokku plugins-install

on 0.4.x

dokku plugin:install https://github.com/dokku/dokku-mongo.git mongo

Also, now, dokku mongo:link YOUR_DB YOUR_APP will create a process.env.MONGO_URL in the YOUR_APP container

Hi, is it possible to scale the service to more instances? If so, how can I do that?

Thank you
