Check container's public IP address

[zero-thermo]

I set up changedetection.io behind a VPN. How do I check its public IP to confirm that it's working properly?

Normally, I run the following:

sudo docker exec -it <$CONTAINER> /bin/bash
curl ifconfig.io

However, the changedetection container does not support the curl, ip, or any other commands that I would normally use to check public IPs in Linux.

What else can I try?

Did you install curl first?
docker exec -it changedetection apt install curl -y
docker exec -it changedetection curl ifconfig.io

Thank you for helping me figure this out

You're asking us to debug your VPN configuration I think, kind of outside the scope of this support forum
