      <Accordion title="Using CLI">
        The Reserved Instance Lease Expiration In The Next 7 Days issue in AWS can be remediated by modifying the reservation period of the instance. Here are the steps to remediate this issue using AWS CLI:

        1. Open the AWS CLI on your local machine.

        2. Run the following command to get a list of all the reserved instances that have an expiration date within the next 7 days:

        ```
        aws ec2 describe-reserved-instances --filters "Name=state,Values=active" "Name=product-description,Values=*Linux/UNIX*" "Name=scope,Values=Availability Zone" --query 'ReservedInstances[*].[ReservedInstancesId,InstanceType,AvailabilityZone,InstanceCount,Start,End,Duration,State,Tags[?Key==`Name`].Value|[0]]' --output table --region <region>
        ```

        Note: Replace `<region>` with the region where your instances are located.

        3. Identify the instance that requires remediation.

        4. Run the following command to modify the reservation period:

        ```
        aws ec2 modify-reserved-instances --reserved-instances-id <reservation_id> --target-configuration "InstanceCount=<count>,End=`date -d '+1 year' +%Y-%m-%d`" --region <region>
        ```

        Note: Replace `<reservation_id>` with the ID of the reserved instance that requires remediation and `<count>` with the number of instances that you want to reserve. Also, ensure that the `End` date is set to at least 1 year from the current date.

        5. Verify that the reservation has been modified by running the first command again and checking that the expiration date is now more than 7 days away.

        By following these steps, you can remediate the Reserved Instance Lease Expiration In The Next 7 Days issue in AWS using AWS CLI.

      <Accordion title="Using Python">
        To remediate the issue of Reserved Instance Lease Expiration in the next 7 days in AWS using Python, follow these steps:

        1. Import the necessary AWS SDK boto3:

        ```
        import boto3
        ```

        2. Create an EC2 client object:

        ```
        ec2 = boto3.client('ec2')
        ```

        3. Use the describe\_reserved\_instances() method to get the list of all reserved instances:

        ```
        reserved_instances = ec2.describe_reserved_instances()
        ```

        4. Loop through the list of reserved instances and check if any of them are expiring within the next 7 days:

        ```
        for reserved_instance in reserved_instances['ReservedInstances']:
            expiration_time = reserved_instance['End']
            remaining_days = (expiration_time.date() - datetime.date.today()).days
            if remaining_days <= 7:
                # Do something to remediate the issue
        ```

        5. To remediate the issue, you can either renew the reserved instance or purchase a new one. To renew the reserved instance, use the modify\_reserved\_instances() method:

        ```
        response = ec2.modify_reserved_instances(
            ReservedInstancesIds=[
                'string',
            ],
            TargetConfigurations=[
                {
                    'AvailabilityZone': 'string',
                    'InstanceCount': 123,
                    'InstanceType': 'string',
                    'Platform': 'string',
                    'Scope': 'string'
                },
            ]
        )
        ```

        6. Alternatively, you can purchase a new reserved instance using the purchase\_reserved\_instances\_offering() method:

        ```
        response = ec2.purchase_reserved_instances_offering(
            InstanceCount=123,
            ReservedInstancesOfferingId='string',
            DryRun=True|False,
            LimitPrice={
                'Amount': 'string',
                'CurrencyCode': 'string'
            }
        )
        ```

        7. Finally, you can schedule a Lambda function to run this script periodically and remediate the issue automatically.
