The repository is a .net core solution and connects to GCP to get instance list with input as project name and zone. The authentication uses default authentication from cloud SDK
1)There should be cloud SDK installed in the development environment where the solution will be running 2) I used cloud SDK default aurthentication to authenticate GCP credential. So you might have to follow the same. Do below to set up the authentication a) Make sure Cloud SDK is installed in your system(windows) b) In the Cloud Console, go to the Create service account key page. Go to the Create Service Account Key page From the Service account list, select New service account. In the Service account name field, enter a name. From the Role list, select Project > Owner.
Note: The Role field authorizes your service account to access resources. You can view and change this field later by using the Cloud Console. If you are developing a production app, specify more granular permissions than Project Owner. For more information, see granting roles to service accounts. Click Create. A JSON file that contains your key downloads to your computer.
c) set environment variable using below With PowerShell:
$env:GOOGLE_APPLICATION_CREDENTIALS="[PATH]"
For example:
$env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\username\Downloads[FILE_NAME].json"
With command prompt:
set GOOGLE_APPLICATION_CREDENTIALS=[PATH] d) Make sure to run below command in your command prompt to make sure your cloud SDK is in default authentication mode gcloud auth application-default login
