I'm not sure if ec2metadata is deprecated. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-data-retrieval.html

@awattez so you think it's more reliable to curl the 169.254.169.254? (Anyway it will be more reliable than using remote ifconfig.co service)

My bad, it appears to be the ec2metadata python script from cloud-utils 📦. it calls the correct url in the python script.

Everything is here : https://github.com/canonical/cloud-utils/blob/main/bin/ec2metadata

The 169.254.169.254 is called in python script :)

But in the Strigo script we have to be sure that we have installed cloud-utils package.

So may be better to do direct call instead of depending on a tool that may not be installed in custom AMIs.

cloud-utils is easier to use, just added the install (instead of curl) to be sure to have it.
