hey friends - if I have a secret that I want to write to a file, for example as input to cloud-init - how do I do that? I get an error that says I should use

apply

... but that doesn't seem to actually let me wind up with a string 🙂

You can provide the return object from the

.apply

directly to a resource input - e.g.

userData

on an

aws.ec2.Instance

.

my problem is I'm composing it with other data, I suspect - so my userdata is an interpolated string, and I can't get a value of out

apply

that seems to ever show up in that string

You can use

.all(...).apply(...)

to combine multiple values into an interpolated string. Here's a contrived, but functional example:

const config = new pulumi.Config()
const mySecret = config.requireSecret("mySecret");

// create the string `vpc-abc123: asdf1234`
const userData = pulumi.all([vpc.id, mySecret]).apply(([vpcId, secret]) => `${vpcId}: ${secret}`);

I see - they're promises

@flaky-father-99093 there’s also a helpful little library for generating cloud init manifests in typescript that joe wrote: https://github.com/joeduffy/pcloudinit
