Azure Devops - Domain name is invalid

Question

I am trying to create a virtual machine using ARM template. I have added ARM template in my visual studio and have checked-in into the Azure Repos. On running release pipeline I am receiving below error:

InvalidDomainNameLabel: The domain name label $(dns) is invalid. It must conform to the following regular expression: ^[a-z][a-z0-9-]{1,61}[a-z0-9]$. []

Below is the parameter.json file:

{
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "adminUsername": {
      "value": "Myadmin"
    },
    "dnsNameForPublicIP": {
      "value": "mynewdevvmbox003"
    }
  }
}

dns name "mynewdevvmbox003" is matching the regular expression requirement but still, I am getting this error.

Just wanted to check in what the status on this issue was? Is it succeed for you to apply the ARM template now? — Mengdi Liang, Dec 12 '19 at 11:42

InvalidDomainNameLabel: The domain name label $(dns) is invalid.

According to this error message, the value of domain name that this task server got is $(dns), not mynewdevvmbox003.

I think you should specified the override parameter value in Override template parameters of Azure resource group deployment task, such as -dnsNameForPublicIP $(dns).

If you indeed specify like this, the value in parameter.json will not be parsed any more. Because the override content has higher priority than parameter.json. Here, dns is a pipeline varibale.

Please ensure select the parameter.json file in Template parameters:

And, do not specify adminUsername and dnsNameForPublicIP again in Override template parameters of the task.
