@here Hi, I am new to pulumi can someone kindly let me know how to add a list to config? is it something like

pulumi config set addressSpaces ['xx.xx.xx.xx/ab','yy.yy.yy.yy/cd']

?

It is! Have you tried it? With the Node.JS SDK you can load the object with

new Config('<project-name>').requireObject('addressSpaces')

. The only caveat is, that it has to be valid JSON for this to work

We don’t currently support list types as configuration values. You can achieve the same thing though by storing a comma delimited value and splitting the value in your pulumi application. We have https://github.com/pulumi/pulumi/issues/2306 to track adding list and map support.

I just tested it and it does actually work since

getObject

/

requireObject

just uses

JSON#parse

under the hood (https://github.com/pulumi/pulumi/blob/375b75be84a4073adf939d0e3001229e4f3f4679/sdk/nodejs/config.ts#L133). If I run

pulumi config set addressSpaces '["xx.xx.xx.xx/ab","yy.yy.yy.yy/cd"]'

to set the config value and run

pulumi up

with the following `index.ts`:

import * as pulumi from "@pulumi/pulumi";
(new pulumi.Config("test").getObject("addressSpaces") as string[]).forEach(
  addr => {
    console.log(`Address: ${addr}`);
  }
);

it outputs as you would expect

test$ pulumi up

Thanks Arne, for the solution. I followed a similar path. but used config.require("vnetAddressSpace").split(',');
