Question

Asked by Richard Kasperowski
Hi!
I have an App that uses a Droplet as a resource.
To firewall the droplet, I need to know the IP address that the app uses when it connects to the droplet.
How do I find out what the app’s IP address is so I can use it in a firewall rule?
Thanks!

Hi there,
Quick update here, you can now add dedicated egress IP addresses to your apps on App Platform. Dedicated egress IP addresses allow your app to connect to resources outside of DigitalOcean using a publicly available static IP address.
Dedicated egress IP addresses are a paid feature that allows your app to connect to resources outside of DigitalOcean using a static IP address and allow you to restrict external resources to receive only outgoing traffic from your app. Dedicated egress IP addresses persist through redeployments but are removed from the app if you disable the feature or the app is destroyed.
You can add a dedicated egress IPs to your app after you deploy the app. To do so, in the DigitalOcean Control Panel, go to the Apps page and click your app. Click the Settings tab, scroll to the Dedicated Egress IP Addresses section, and then click the Edit button beside the section.
In the Edit menu, click the Add Dedicated Egress IP button. This assigns two IP addresses to your app and triggers a redeployment.
To remove a dedicated egress IP address, in the same Edit menu, click Release Dedicated Egress IPs. This removes the IP addresses from the app and triggers a redeployment. Once IP addresses have been released, the same addresses cannot be re-added to the app.
Hope that this helps!
Best,
Bobby
Hey @richardkasperowski,
At the moment, you can only do that with the App platform and a managed database cluster. You can’t do this with a Droplet as the App Platform does not come with a static IP address.
It looks like someone has had the same idea before and has posted it on our Product Ideas board. The best thing to do would be to head over and add your vote to it, as well as adding any additional information in the comments for exactly what you’d like to see implemented!
Hope that helps!
- Bobby.
Hooray!
