Dynamic IPs and Trusted Sources

Question

Context :During development it’s helpful to access my MongoDB database and run it on local host. I secure the database by adding my IP to the “trusted sources” on the DO dashboard. Problem :The problem is that my IP is dynamic. This forces me to remove the old IP and replace it with my new one. There has got to be a better way to do this… Possible Solution :One of my ideas is to write a script that appends and removes firewall rules using ‘doctl.’ But if someone has a better idea, I would love to hear it! thanks

Hello there! Great question, and it’s a common challenge for developers working with dynamic IP addresses, especially when securing access to your databases. Let’s explore a couple of solutions to make your life easier! Using a VPN A very effective way to bypass the dynamic IP issue is to use a VPN. This approach allows you to maintain a consistent IP address for your development environment, regardless of changes by your ISP. DigitalOcean’s Marketplace offers a solution called Pi-hole + OpenVPN, which you can set up with a single click. This not only helps with secure and private browsing but can also simplify your access management to MongoDB by having a static IP. Check out the Pi-hole + OpenVPN on DigitalOcean’s Marketplace here: Pi-hole VPN . Automating with doctl For your idea of automating the update of your trusted sources rules, doctl is indeed a powerful tool in your arsenal. Here’s a basic example of how you could use doctl to update your firewall rules, specifically for managing access to your MongoDB database: Install doctl : First, ensure you have doctl installed. You can find the installation instructions on the DigitalOcean documentation . Authenticate doctl : Make sure you’ve authenticated doctl with your DigitalOcean account. You’ll typically do this with an API token: doctl auth init Script for Updating your Rules : You can write a simple script that fetches your current IP and updates the trusted sources rule. Here’s a very basic example: #!/bin/bash # Fetch your current public IP MY_IP=$(curl -s https://ifconfig.io/) # Specify your managed database ID DATABASE_ID="your-database-id" # Update the database firewall rules (trusted sources) # Note: Adjust --uuid with your actual DATABASE_ID and --rule with the appropriate IP doctl databases firewalls update $DATABASE_ID --rule type:ip, value:$MY_IP --force echo "Database trusted sources rules updated to allow access from $MY_IP" For more information you can check out the docs here: https://docs.digitalocean.com/reference/doctl/reference/databases/firewalls/list/ I would personally go for using a VPN with a static IP simplifies access management without needing to adjust firewall rules constantly. However, automating updates with doctl provides a flexible, immediate solution as well. Depending on your workflow and security requirements, you might find one option more suitable than the other. Happy coding, and stay secure! Best, Bobby

Heya @58215a70856347b792e785248632d2 , My idea would be using a VPN which has a static IP address. It’s not perfect as well but that is how I do it.
