I suspect you need to use that like this:

```subnetId: pulumi.output(vpc.publicSubnetIds)[0],```

As it was, I think it comes through as `undefined` which means AWS tries to put it in the default VPC which would be a different vpc.

perfect... instances now created successfully :slightly_smiling_face:

I think it would be good to mention this in the example code.

Indeed! Do you mind sharing where you saw that example code?

i use the VPC, SG code from here <https://www.pulumi.com/docs/guides/crosswalk/aws/vpc/>

and EC2 code from here <https://www.pulumi.com/docs/tutorials/aws/ec2-webserver/>

just combined both together with some additional parameters to create e2e deployment example.
