IBM Cloud Code Engine: How to get IP addresses for my app, so that I can allowlist it?

Question

I have an IBM Cloud Code Engine project with a deployed container app. That app needs to access a protected resource. I need to configure an allowlist and add the IP address(es) for the app.

How do I find those IP addresses? Is there an official list?

Answer 1

I found the following API function for IBM Cloud Code Engine to list egress IP addresses.

In a shell and with the IBM Cloud CLI with Code Engine plugin, I performed the following steps:

• log in to IBM Cloud
• ibmcloud iam oauth-tokens --output json to obtain the access token
• ibmcloud ce project list to obtain the Code Engine project ID and region of my project
• curl -X GET "https://api.REGION.codeengine.cloud.ibm.com/v2/projects/PROJECT_ID/egress_ips" -H "Authorization: Bearer TOKEN" replace the parameters and call the API function

The list of returned IP addresses needs to be added in the allowlist.
