Hi I'm new to pulumi I'm running the following code

server = aws.ec2.Instance(
    "pulumi_made",
    ami=ami.id,
    vpc_security_group_ids=[security_group.id],
    instance_type="t2.micro",
    tags=common_tags,
    key_name=ec2_key_name,
    # availability_zone="us-east-1a",
    ebs_block_devices=[aws.ec2.InstanceEbsBlockDeviceArgs(
        delete_on_termination=True,
        volume_size=10,
        device_name="/dev/sda1"
    )],
    volume_tags=common_tags
)

everytime I run

pulumi up

it recreates a new instance even if the code has not changed. what am I doing wrong? i couldnt find anything in docs.

where are u storing the state? and are u using the same state backend everytime?
