Running Azure SDK for Go return an error: MSI not available

Question

I am trying to run Golang Azure SDK code to get a list of RGs in my subscriptions but I am getting the following error:

2022/01/22 20:25:58 MSI not available exit status 1

import (
    "context"
    "fmt"
    "github.com/Azure/azure-sdk-for-go/services/resources/mgmt/2020-10-01/resources"
    "github.com/Azure/go-autorest/autorest/azure/auth"
    "github.com/Azure/go-autorest/autorest/to"
    "log"
    "os"
)

func main() {
    authorize, err := auth.NewAuthorizerFromEnvironment()

    if err != nil {
        log.Fatal(err)
    }

    subscriptionID := os.Getenv("AZURE_SUB_ID")

    //Read resource groups
    resGrpClient := resources.NewGroupsClient(subscriptionID)
    resGrpClient.Authorizer = authorize

    //Read resources within the resource group
    resClient := resources.NewClient(subscriptionID)
    resClient.Authorizer = authorize

    for resGrpPage, err := resGrpClient.List(context.Background(), "", nil); resGrpPage.NotDone(); err = resGrpPage.Next() {

        if err != nil {
            log.Fatal(err)
        }

        for _, resGrp := range resGrpPage.Values() {
            fmt.Println("Resource Group Name: ", to.String(resGrp.Name))
            resList, _ := resClient.ListByResourceGroup(context.Background(), to.String(resGrp.Name), "", "", nil)

            for _, res := range resList.Values() {
                fmt.Println("\t- Resource Name: ", to.String(res.Name), " | Resource Type: ", to.String(res.Type))
            }
        }

    }

}

I am using Goland and trying to run the app in WSL Ubuntu

Answer 1

Please read this documentation Use environment-based authentication

You have a couple of options and they need specific environments variables to be present. In my case, I use Client credentials so I need to have these 3 envs present when I run my code.

1. AZURE_CLIENT_ID
2. AZURE_CLIENT_SECRET
3. AZURE_TENANT_ID

Answer 2

Solution is to use auth.NewAuthorizerFromCLI(), as auth.NewAuthorizerFromEnvironment does not use the Cli and MSI stands for managed system identity.
