@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
just uses
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`:
Copy code
import * as pulumi from "@pulumi/pulumi";
(new pulumi.Config("test").getObject("addressSpaces") as string[]).forEach(
  addr => {
    console.log(`Address: ${addr}`);
it outputs as you would expect
Copy code
test$ pulumi up
Previewing update (dev):

     Type                 Name      Plan       Info
 +   pulumi:pulumi:Stack  test-dev  create     2 messages
  pulumi:pulumi:Stack (test-dev):
    Address: xx.xx.xx.xx/ab
    Address: yy.yy.yy.yy/cd
    + 1 to create
But of course I only tested it with the Typescript SDK. It might be different for the other ones?!
Thanks Arne, for the solution. I followed a similar path. but used config.require("vnetAddressSpace").split(',');
