Connect to a Linux instance by using a password.
Run curl http://100.100.100.200/latest/meta-data/ to access the root directory of the metadata.
Add the specific metadata name to the preceding command to access the specified metadata. For example: Run curl http://100.100.100.200/latest/meta-data/instance-id to get the ID of an ECS instance. Run curl http://100.100.100.200/latest/meta-data/image-id to get the image ID of an ECS instance.

For Windows Instances
