Question
How to connect APP Platform to external database?

Asked by sergio t. ruiz
I have an APP that I have just deployed to the APP Platform. It looks like it runs fine, but I cannot connect to my remote database. In order to connect to the remote database, I need to add the APP’s IP to the security group.
I don’t see how to get the IP address for the APP (I would like to use a Flexible IP with it), so pinged the IP address and added that to the security group. I had no luck with that.
Does anyone have any hints?

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
Hi @sergiot-ruiz,
Unfortunately, App Platform applications do not have a persistent IP address. More about that here
https://docs.digitalocean.com/products/app-platform/how-to/manage-databases/
Regarding the connection to an external database, there is a similar question asked here:
https://www.digitalocean.com/community/questions/static-ips-whitelisting
The main answer there is:
App Platform apps do not have a static-IPs. We’ve heard requests for static IPs as an add-on feature and are considering it. In the mean time, we recommend using TLS encryption and strong authentication to secure connections to external resources.
