not creating both at the same time

resources can only be managed by one program, trying to have separate stacks manage the same resource can be done but is a source of much error and confusion

any reference links for this

You can either use the

pulumi import

command, or use the

import

resource option.

importing will add the existing resource to the stack so that pulumi understands it's current state and can do an update rather than a create.

@echoing-dinner-19531 One more thing, I have imported the resource to my stack 2 and now I'm able to update it, when I try to get the existing resource from stack 1 and try to update the first stack with the value got from get() it results awsservicediscoveryInstance Service_Instance replace [diff: -attributes,instanceId,serviceId] and failed with "*panic: fatal: An assertion has failed*" If I remove, getting instance and updating the value which was updated by stack 2 I'm getting result but the updated value is removed. Got confused what happening now

In stack 1 instead of updating why it is trying to replace ? The stack already has this service instance, then it must update it right?
