Hello I m just getting started with Pulumi in a Webiny proje

Question

Hello I m just getting started with Pulumi in a Webiny project I need to simulate a Terraform `data` block I saw that this can be done by `aws ec2 getVpc ` However this returns a `Promise lt aws ec2 GetVpcResult gt ` instead of a `Vpc` which has `pulumi Output lt string gt ` properties and the two objects are very different Am I barking up the right tree here I see the static `Vpc get ` method but it has parameters I don t know the meaning of such as `id pulumi Input lt pulumi ID gt ` what would I pass in there If I go down the `getVpc ` route with the Promise could I end up having any kind of race condition issue between the time the details of that VPC are fetched and the actual stack deploys

If you re just getting data from the VPC object then you can use `getVpc ` You won t get a Vpc object

If you want to manage the Vpc in Pulumi equivalent to a `resource` in Terraform then you must import the VPC

And half way between those options is `Vpc get ` which is similar to `getVpc` but uses the normal Pulumi classes It s read only though so similar to a `data`

I would suggest not trying to simulate anything Terraform y You will need a new mental model as Terraform and Pulumi require fairly different ways of thinking

Thanks for the info I need to simply use existing VPCs that Pulumi will not manage

I m not really trying to simulate anything in Terraform I said simulate just to convey the goal get a reference to a resource and use it without Pulumi controlling or creating that resource

It s very clear to me that Pulumi s lifecycle is a different way of thinking about things than normal code but it is in fact close to how Terraform does things though that may not be apparent to some from looking at hcl code which almost looks procedural

Ok Well then you can use `Vpc get ` or `getVpc ` either is good and they have very different APIs and returned objects
