How do I host Rails app DigitalOcean?

Last updated on December 17, 2022 @ 2:25 pm

There are many ways to host a Rails app on DigitalOcean. The following article will outline how to set up a Rails app on DigitalOcean using the Droplet image format.

After setting up your Droplet, you will need to configure your app to use the DigitalOcean networking interface.

1. To get started, create a new Droplet by clicking the “Create Droplet” button on the DigitalOcean website.

2. Enter the following information into the “Droplet Information” field and click the “Create Droplet” button.

Name: rails

Size: 1GB

Operating System: Ubuntu 16.04

3. DigitalOcean will create a Droplet for you and assign it the name rails.

4. To verify the information you entered, click the “View Droplet Details” link in the droplet’s Overview page.

5. The next step is to create a Droplet instance. To do this, click the “Create Droplet” button on the DigitalOcean website and enter the following information into the “Droplet Information” field.

6. To create an instance, you will need a Droplet image.

7. To get started, click the “Select an Image” link in the Droplet Details page and search for the Rails image.

8. Once you have found the image, click the “Download” button to download it to your computer.

9. Once you have the image, you will need to extract the contents of the image to a directory on your computer. To do this, open a terminal window and navigate to the directory where you downloaded the image.

10. To extract the image, you will need the droplet-create command line utility. To install the droplet-create utility, enter the following command into the terminal window:

sudo apt-get install droplet-create

11. Once you have the droplet-create utility installed, enter the following command to extract the image to a directory on your computer:

sudo droplet-create rails –name rails –size 1gb –image rails.img

12. The next step is to create a .yml file to configure your Droplet instance. To do this, open a terminal window and navigate to the directory where you extracted the image.

13. To create the .yml file, enter the following command:

sudo droplet-create rails –name rails –size 1gb –configuration=” droplet.yml ”

PRO TIP: This is a potentially dangerous question. Rails apps can be difficult to host, and unless you know what you’re doing, it’s easy to make a mistake that could lead to data loss or security vulnerabilities. If you’re not sure how to host a Rails app, we recommend finding someone who does and asking them for help.

14. The –configuration flag is important. The .yml file will be used to configure your Droplet instance.

The following is a sample .yml file.

image: rails

size: 1gb

name: rails

region: us-east1

networking:

interface: wlan0

networking.public_dns: 8.8.8.

networking.private_dns: 8.4.

15. The next step is to configure your Droplet instance to use the DigitalOcean networking interface. To do this, open a terminal window and enter the following command:

auth:

username: rails

password: 123456

16. The next step is to configure your app to use the DigitalOcean networking interface.
