Install-SitecoreConfiguration : Cannot validate argument on parameter 'DnsName'

Question

I'm installing a pre-release version 10.1.3.
For this I have installed 10.1.2 using the Graphical setup.
Then placed these files in the root folder of the extracted 10.1.2 files.

- Sitecore 10.1.3 rev. 008034 (DELTA WDP XM1 packages).zip
- Sitecore 10.1.3 rev. 008034 (DELTA WDP XP0 packages).zip
- Sitecore 10.1.3 rev. 008034 (DELTA WDP XP1 packages).zip

In the XP0-SingleDeveloper.json file and set the Update parameter to true.

Now when I execute this command in Powershell Install-SitecoreConfiguration -Path .\XP0-SingleDeveloper.json I see this error:

Install-SitecoreConfiguration : Cannot validate argument on parameter 'DnsName'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

Also, if this was success, will it create a new instance with v10.1.3 or will it update the existing instance, because I have not changed any other setting in the XP0-SingleDeveloper.json.

Answer 1

The xp0-SingleDeveloper.json file has a section where it pulls in other config files (namely Sitecore-XP0.json):

"Includes": {
    "SitecoreXP0": {
        "Source": ".\\Sitecore-XP0.json"
    }
},

Within the Sitecore-XP0.json file, there is a parameter called DnsName, which defaults to using the SiteName parameter (which defaults to 'Sitecore'):

"DnsName" :{
    "Type": "string",
    "Reference": "SiteName",
    "Description": "The dns name of the site."
},

So it looks like this parameter may not have been set properly. Please review your Sitecore-XP0.json file and confirm SiteName parameter has been set. The value should be the root domain only (i.e. not include http:// prefix). The value used should be resolvable on your local instance.

Alternatively, you can pass in those parameters at the command line. For example:

Install-SitecoreConfiguration -Path .\XP0-SingleDeveloper.json -SiteName your-domain.com

I think you will also need to update the package parameter in relevant config files to point to the new delta packages. So in Sitecore-XP0.json:

"Package": {
    "Type": "string",
    "Description": "The path to the Web Deploy package to deploy.",
    "DefaultValue": ""
},
