I m trying to use one instance s privateIp in the user data

Question

I m trying to use one instance s privateIp in the user data of another instance I tried doing something like ```function getIp server aws ec2 Instance return pulumi all server privateIp apply privateIp = gt return pulumi interpolate`$ privateIp ` ``` to get the IP but it still gives me the calling toString on an output error instead of the value Thoughts on how to do this

You can use `pulumi interpolate` directly in that case ```const userData = pulumi interpolate` IP Address $ instance publicIp Subnet ID $ vpc publicSubnetIds 0 ` ```

For two strings you can use all and then apply
