Looks good to me. |
ec2-metadata does not support all meta-data listed in the document. [0]
Let's support such meta-data with a generic option, --path.
It can be specified multiple times and used with other options:
$ ./ec2-metadata --path events/maintenance/scheduled \
--path meta-data/identity-credentials/ec2/security-credentials/ec2-instance \
--region
latest/meta-data/events/maintenance/scheduled: []
latest/meta-data/identity-credentials/ec2/security-credentials/ec2-instance: {
"Code" : "Success",
"LastUpdated" : "2025-04-07T04:58:06Z",
"Type" : "AWS-HMAC",
...
"Expiration" : "2025-04-07T11:01:19Z"
}
region: ap-northeast-1
Also, it can be used to fetch non-latest meta-data and dynamic data:
$ ./ec2-metadata --path /
/: 1.0
2007-01-19
...
$ ./ec2-metadata --path /2009-04-04/dynamic
/2009-04-04/dynamic: instance-identity/
