Example 1: To stop an Amazon EC2 instance

The following stop-instances example stops the specified Amazon EBS-backed instance.

aws ec2 stop-instances \
    --instance-ids i-1234567890abcdef0

Output:

{
    "StoppingInstances": [
        {
            "InstanceId": "i-1234567890abcdef0",
            "CurrentState": {
                "Code": 64,
                "Name": "stopping"
            },
            "PreviousState": {
                "Code": 16,

            }
        }
    ]
}

Example 2: To hibernate an Amazon EC2 instance

The following stop-instances example hibernates Amazon EBS-backed instance if the instance is enabled for hibernation and meets the hibernation prerequisites. After the instance is put into hibernation the instance is stopped.

aws ec2 stop-instances \
    --instance-ids i-1234567890abcdef0 \
    --hibernate

Output:

{
    "StoppingInstances": [
        {
            "CurrentState": {
                "Code": 64,
                "Name": "stopping"
            },
            "InstanceId": "i-1234567890abcdef0",
            "PreviousState": {
                "Code": 16,
                "Name": "running"
            }
        }
    ]
