To get the private IP address of an Amazon EC2 instance, you can use either of the following describe-instances AWS CLI commands:

Important: Replace <instance-id> with your Amazon EC2 instance's ID. Replace <your-private-dns-name> with the private DNS name of the network interface.

aws ec2 describe-instances --instance-id <instance-id> --query 'Reservations[0].Instances[0].NetworkInterfaces[?Attachment.DeviceIndex==`1`].PrivateIpAddress'

-or-

aws ec2 describe-instances --filters Name=private-dns-name,Values=<your-private-dns-name> --query 'Reservations[0].Instances[0].NetworkInterfaces[?Attachment.DeviceIndex==`1`].PrivateIpAddress'
