Azure pipeline - terratest - ERROR: Please run 'az login' to setup account

6.5k views Asked by Philippe Carpentier At 07 September 2024 at 20:29

i'm facing a (it seams) recurent pbm in Azure Pipeline to run terratest.

While resources are well created the destroyed, when I call an azure.ResourceGroupExists function (or whatever else azure.xxx function) i have the following error :

--- FAIL: TestTerraform_RM_resource_group (102.30s)
    resourcegroup.go:15: 
            Error Trace:    resourcegroup.go:15
                                        RM_resource_group_test.go:108
            Error:          Received unexpected error:
                            Invoking Azure CLI failed with the following error: ERROR: Please run 'az login' to setup account.
            Test:           TestTerraform_RM_resource_group
FAIL

Regarding some forum, It seems to be some configuration issue, and I follow all these recomanded configuration :

set environments variables for terraform : -- ARM_CLIENT_ID -- ARM_CLIENT_SECRET -- ARM_SUBSCRIPTION_ID -- ARM_TENANT_ID
set the az login in AzureCli task outside the go task for terratest, as it seems that terratest needs 2 differents authentifications : (using service principal client id for this az login)
For Assert tests, needs the ARM_CLIENT authentification
for Exists tests, needs the Service connection authentification

here the link I follow :

bellow my pipeline code, where the TF_VAR_ARM_CLIENT_SECRET is a secret variable of the pipeline

        },


        EnvVars: globalEnvVars,

        NoColor: true,

    })



    // website::tag::4::Clean up resources with "terraform destroy". Using "defer" runs the command at the end of the test, whether the test succeeds or fails.
    // At the end of the test, run `terraform destroy` to clean up any resources that were created
    defer terraform.Destroy(t, terraformOptions)

    // website::tag::2::Run "terraform init" and "terraform apply".

    exists := azure.ResourceGroupExists(t, expectedName, subscriptionID)
    assert.True(t, exists, "Resource group does not exist")
}

I'm sure I miss something in passing my parameters, as always I have the following error, after creating and destroying resources in Azure :

--- FAIL: TestTerraform_RM_resource_group (90.75s)
resourcegroup.go:15: 
        Error Trace:    resourcegroup.go:15

please, help.

and thank-you for answering..

As I figure out earlier, it was a configuration mistake and, after having made some deep excavations on Go Terratest Azure module, I've found these lines that gives all the explanations :

So I change my pipeline to this :

# Go test command
- task: Go@0
  displayName: 'Run Go terratest for resource_Modules'
  inputs:
    command: test
    arguments: '$(TF_LOG) $(pathToTerraformRootModule)\...'
  env:
    ARM_SUBSCRIPTION_ID: $(TF_VAR_ARM_SUBSCRIPTION_ID)
    AZURE_CLIENT_ID: $(TF_VAR_ARM_CLIENT_ID)
    AZURE_TENANT_ID: $(TF_VAR_ARM_TENANT_ID)
    AZURE_CLIENT_SECRET: $(TF_VAR_ARM_CLIENT_SECRET)
    resource_group_name: $(storageAccountResourceGroup)
    storage_account_name: $(storageAccount)
    container_name: $(stateBlobContainer)
    key: '$(MODULE)-$(TF_VAR_APPLICATION)-${{ parameters.Environment }}.tfstate'

And my Go code to this (regarding the envVariables use) :

// getting enVars from environment variables
ARM_CLIENT_ID := os.Getenv("AZURE_CLIENT_ID")
ARM_CLIENT_SECRET := os.Getenv("AZURE_CLIENT_SECRET")
ARM_TENANT_ID := os.Getenv("AZURE_TENANT_ID")
ARM_SUBSCRIPTION_ID := os.Getenv("ARM_SUBSCRIPTION_ID")

// creating globalEnVars for terraform call through Terratest
if ARM_CLIENT_ID != "" {
    //globalEnvVars["ARM_USE_MSI"] = "true"
    globalEnvVars["ARM_CLIENT_ID"] = ARM_CLIENT_ID
    globalEnvVars["ARM_CLIENT_SECRET"] = ARM_CLIENT_SECRET
    globalEnvVars["ARM_SUBSCRIPTION_ID"] = ARM_SUBSCRIPTION_ID
    globalEnvVars["ARM_TENANT_ID"] = ARM_TENANT_ID
}


// getting backend vars from environment variables
resource_group_name := os.Getenv("resource_group_name")
storage_account_name := os.Getenv("storage_account_name")
container_name := os.Getenv("container_name")
key := os.Getenv("key")

// creating globalBackendConf for terraform call through Terratest
if resource_group_name != "" {
    //globalBackendConf["use_msi"] = true
    globalBackendConf["resource_group_name"] = resource_group_name
    globalBackendConf["storage_account_name"] = storage_account_name
    globalBackendConf["container_name"] = container_name
    globalBackendConf["key"] = key
}

// User Terratest to deploy the infrastructure
terraformOptions := terraform.WithDefaultRetryableErrors(t, &terraform.Options{
    // website::tag::1::Set the path to the Terraform code that will be tested.
    // The path to where our Terraform code is located
    TerraformDir: fixtureFolder,
    // Variables to pass to our Terraform code using -var options
    Vars: map[string]interface{}{
        "STAGE": inputStage,
        "ENVIRONMENT": inputEnvironment,
        "APPLICATION" : inputApplication,
        //"configuration" : inputConfiguration,
    },


    // globalvariables for user account 
    EnvVars: globalEnvVars,

    // backend values to set when initialziing Terraform
    BackendConfig: globalBackendConf,
    
    // Disable colors in Terraform commands so its easier to parse stdout/stderr
    NoColor: true,

})

And all goes right ! Hopes this could help others.

Thanks again.

[EDIT] To be more explicit :

Go and Terraform uses two differents methods for Azure authentification.

** Terraform authentification is explained bellow :

https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/guides/service_principal_client_secret#configuring-the-service-principal-in-terraform

** Go authentification is explained bellow :

https://learn.microsoft.com/en-us/azure/developer/go/azure-sdk-authorization#use-environment-based-authentication

** Terratest is using both authentification methods regarding the work it has to be done :

azure existences tests uses Go azure authentification :
- https://github.com/gruntwork-io/terratest/blob/master/modules/azure/authorizer.go#L11
terraform commands uses terraform authentification :
- https://github.com/gruntwork-io/terratest/blob/0d654bd2ab781a52e495f61230cf892dfba9731b/modules/terraform/cmd.go#L12
- https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/guides/service_principal_client_secret#configuring-the-service-principal-in-terraform

so both authentification methods have to be implemented
