Go SDK for Azure How to create a virtual machine without a service principal?

Question content

This sample code in the Go SDK creates a virtual machine by deploying an ARM template. It requires you to include the clientId and clientSecret from the service principal.

This sample code from Go SDK creates a virtual machine using the Go SDK for Azure. It requires a subscription ID but not a service principal (client ID, client secret). It also does not automatically create service principals.

I thought that creating a virtual machine requires a service principal, but the GO SDK sample is able to create a virtual machine without specifying a service principal. What am I missing about service principals and virtual machines?

Correct answer

It uses newdefaultazurecredential, this class retrieves authentication information from the environment (e.g. azure cli, environment variables) - View documentation

func connectionAzure() (azcore.TokenCredential, error) {
    cred, err := azidentity.NewDefaultAzureCredential(nil)
    if err != nil {
        return nil, err
    }
    return cred, nil
}
