Hello Everyone, I am trying to use Pulumi with Yaml file and when I try to do

pulumi preview

, I get the following error:

Previewing update (shared.shared):
     Type                                     Name                       Plan       Info
 +   pulumi:pulumi:Stack                      svcmeshdemo-shared.shared  create
     └─ azure-native:resources:ResourceGroup  resourceGroup                         1 error


Diagnostics:
  azure-native:resources:ResourceGroup (resourceGroup):
    error: azure-native:resources:ResourceGroup resource 'resourceGroup' has a problem: 'resourceGroupName' does not match expression '^[-\w\._\(\)]+$'

My

Pulumi.yaml

file is as follows:

name: svcmeshdemo
runtime: yaml
description: A minimal Azure Native Pulumi YAML program
config:
  env:
    type: string
    default: ${env}
  project:
    type: string
    default: ${project}
  projectShort:
    type: string
    default: ${projectShort}
  customer:
    type: string
    default: ${customer}
  customerShort:
    type: string
    default: ${customerShort}
  namePrefix:
    type: string
    default: ${customerShort}-${projectShort}
  namePrefixCleaned:
    type: string
    default: ${customerShort}${projectShort}

resources:
  # Create an Azure Resource Group
  resourceGroup:
    type: azure-native:resources:ResourceGroup
    properties:
      resourceGroupName: ${namePrefix}-${env}
      tags:
        Project: ${project}
        Environment: ${env}
        Source: Pulumi
        Customer: ${customer}
        Creator: ${customer}

Does anyone know what the problem is and how to fix it? Thanks 🙂

Hi @adventurous-mechanic-24805, it depends on the value of

resourceGroupName

, so on the values of

customerShort

,

projectShort

, and

env

. Somehow the resulting name is invalid. Does

env

maybe end in a

.

?

You maybe right. When you mention the

env

, does it take the pulumi stack environment or the

env

from

Pulumi.shared.shared.yaml

because the environment is

shared.shared

, but I want to reference it from the

Pulumi.shared.shared.yaml

whose value is

shared

I’m not sure where

env

is from. I’m not super familiar with Pulumi yaml and it’s actually not mentioned on https://www.pulumi.com/docs/reference/yaml/.

I figured out the problem. It was this part:

${namePrefix}-${env}

I resolved it by replacing

config

with

variables

because I am reusing the variables. But, thank you anyways
