I need to whitelist my application IPs from third party services for them to allow api calls from my backend app. I am unabled to retrieve these ip addresses, both on production (static ip) and on dev (no static ip)

It’s related to this issue For my production cluster, the 3 Elastic IP addresses on my aws console do not work.

Did you set static IPs for your cluster?

Hi @rophilogene, Yes we did it for the production cluster

Sorry if the question looks stupid, can you confirm the IP you’re looking for are the ones in “Allocated IPv4 address”?

Looking at your account, I can see your Allocated IPv4 Elastic IP addresses:

$ aws ec2 describe-addresses | jq -r '.Addresses[].PublicIp'
13.36.xxx.yyy
13.36.xxx.yyy
13.37.xxx.yyy

Connecting to two of your containers, and looking at the outgoing IP address, I clearly those listed above:

$ dig +short txt ch whoami.cloudflare @1.0.0.1
"13.37.xxx.yyy"

$ dig +short txt ch whoami.cloudflare @1.0.0.1
"13.36.xxx.yyy"

This works on your production cluster because you’ve configured “Static IP” as @rophilogene mentionned. However it’s not set on your dev cluster, so it’s not possible to whitelist IPs.

Thanks its very clear, the issue i am experiencing should be related to something else then. I’ll keep this thread updated.
