:wave:  Folks,

I’m new to pulumi.

My goal is to write out an ssh config file based on an array of instances that I’ve created.

Can someone please point me to the correct way of writing this array of Output interpolated strings to a file?

```export const sshConfigFragments = instances.map((instance) =&gt; {
  return pulumi.interpolate`Host ${instance.tagsAll["Name"]}
    HostName ${instance.privateIp}
    User ec2-user
    UserKnownHostsFile /dev/null
    StrictHostKeyChecking no
`;
});```


What is the type of `instances`? And are you wanting to write the file to your local machine?

instances is an array of `new aws.ec2.Instance`

Yes, I want to write the file to my local machine

Something like this should work:
```pulumi.all(sshConfigFragments).apply(f =&gt; fs.writeFileSync("~/.ssh/config", f.join("\n\n")));```


You'll have an array of `Output` values that you need to wait on and `pulumi.all` does that. Similar to `Promise.all` . Note that `pulumi` in my snippet is just an import alias for `@pulumi/pulumi`.

...and `fs` is an import alias for Node's native `fs` module.
