A bunch of my resources are replaced every time I run

pulumi up

even though no changes have been made in their definitions. Is there a way to prevent this unnecessary churn? My pulumi program is using the python libraries if that makes any difference.

hey there, this shouldn't happen if there's no changes. could you show the diff and the code?

@billowy-army-68599 Sorry, didn’t see your reply till now. For example:

+-  ├─ aws:ecr:LifecyclePolicy  cc-bidder-proxy-policy        replace     [diff: ~policy]
 +-  ├─ aws:ecr:LifecyclePolicy  cc-nginx-policy               replace     [diff: ~policy]
 +-  ├─ aws:ecr:LifecyclePolicy  cc-bidder-policy              replace     [diff: ~policy]
 +-  ├─ aws:ecr:LifecyclePolicy  cc-nginx-log-archiver-policy  replace     [diff: ~policy]
 +-  ├─ aws:ecr:LifecyclePolicy  cc-backend-policy             replace     [diff: ~policy]
 +-  ├─ aws:ecr:LifecyclePolicy  cc-redis-policy               replace     [diff: ~policy]

Details:

Code:

                "countNumber": 15
            },
            "action": {
                "type": "expire"
            }
        }
    ]
}
""")

could you file an issue for this in pulumi-aws, this shouldn't be happening. sorry for the inconvenience

Sure, no problem
