Question

Can the `parent` of a resource be via a stack reference I want to ignore changes of child resources X on the parent stack and have other stacks contribute one or more children

My actual example is Event Grid subscriptions in Azure though it would apply to SNS subscriptions in AWS

No You cannot move resources between stacks like that You can grab a resource s ID from another stack and create a read only version of the resource and make that the parent but that s liable to cause problems later e g when deleting resources

But the parent attribute doesn t mean anything important at the provider level It s only used for drawing resource graphs e g in pulumi preview and opt inheritance Just go with null parent or this if it s in a ComponentResource

Ah gotcha Can a read only parent have a read write child

Also if it s read only in the child stack I m assuming the only way of getting it into state is by doing a refresh

No it s a full resource but it doesn t provision update it Onesec I ll find the docs

little-cartoon-10569 · Answer

Heh it s not documented as a separate concept Just the get functions in each resource <https www pulumi com docs reference pkg azure eventgrid eventsubscription look up>

So you d need the id to be passed by StackReference then use it in the 2nd stack The name doesn t have to match and could be used to emphasize that it is a read only resource managed in a different stack
