oh yeah, I have one problem when implement that way in create ec2 case. I created code like this

const production = config.requireBoolean("environment-production");
const development = config.requireBoolean("environment-development");
if (production) {
const serverProd = new aws.ec2.instance("serverProd", {
    ...
}) 

export const serverIP = serverProd.ip (is not working)
}

if (development) {
const serverDev = new aws.ec2.instance("serverDev", {
    ...
}) 
export const serverIP = serverDev.ip (is not working)
}

I can’t sent output of ip public/private from the server, because the export can’t working inside the condition. How I can export the ip to another file/resource? thank you

If you are creating an EC2 instance in every environment, try varying the args instead, e.g.:

const stackName = pulumi.getStack();
const ec2Args = getEc2Args(stackName); // returns e.g. a t2 micro if stackname == dev, m5g.medium in prod (or whatever)

const server = new aws.ec2.instance("server", ec2Args);
