no Auth Provider found for name "azure"
Hello, all. I would like to share my question rather than issue. I have created AKS cluster successfully using terraform with following code:
resource "azurerm_subnet" "aks_subnet" {
name = var.subnet_name
resource_group_name = var.resource_group_name
virtual_network_name = var.vnet
address_prefixes = var.address_prefixes
}
resource "azurerm_kubernetes_cluster" "aks" {
name = var.k8s_cluster_name
dns_prefix = var.k8s_cluster_name
location = var.resource_group_location
resource_group_name = var.resource_group_name
kubernetes_version = var.kubernetes_version
default_node_pool {
name = var.k8s_default_np_name
orchestrator_version = var.kubernetes_version
node_count = var.node_count_default_np
vm_size = var.k8s_vm_size_system_np
vnet_subnet_id = azurerm_subnet.aks_subnet.id
}
identity {
type = var.identity_type
}
role_based_access_control {
enabled = var.role_based_access_control
azure_active_directory {
managed = var.ad_managed
admin_group_object_ids = var.admin_group_object_ids
}
}
network_profile {
load_balancer_sku = var.load_balancer_sku
outbound_type = var.outbound_type
network_plugin = var.network_plugin
network_policy = var.network_policy
}
}
resource "azurerm_kubernetes_cluster_node_pool" "user" {
name = var.k8s_user_np_name
kubernetes_cluster_id = azurerm_kubernetes_cluster.aks.id
vm_size = var.vm_size
node_count = var.node_count
}
# ---------------------------------------------------------------------------------------------------------------------
# CREATE KUBECONFIG FILE
# ---------------------------------------------------------------------------------------------------------------------
resource "local_file" "kubeconfig" {
content = azurerm_kubernetes_cluster.aks.kube_config_raw
filename = "../../../../kubeconfig"
depends_on = [
azurerm_kubernetes_cluster.aks
]
}
And I wanted to do use terratest so I found an aks terratest https://github.com/gruntwork-io/terratest/blob/master/test/azure/terraform_azure_aks_example_test.go example, which tests deployment:
package test

defer terraform.Destroy(t, vnetOpts)
terraform.InitAndApply(t, vnetOpts)
varAddressPrefixes := []string{"10.1.0.0/23"}
varNodeCount := 3
varVmSize := "standard_d2s_v4"
// Deploy Kubernetes
kubernetesOpts := &terraform.Options{
TerraformDir: "../../examples/azure/kubernetes",

}
defer terraform.Destroy(t, kubernetesOpts)

}
func createK8sVnetOpts(t *testing.T) *terraform.Options {
varResourceGroup := helpers.GenerateRgName()
varResourceGroupLocation := "northeurope"
varVnetName := helpers.GenerateVnetName()
varVnetAddressSpace := []string{"10.1.0.0/23"}
return &terraform.Options{

},
}
}
func TestTerraformAzureAKSExample(t *testing.T) {
t.Parallel()
// Path to the Kubernetes resource config we will test
kubeResourcePath, err := filepath.Abs("../../examples/azure/kubernetes/terraform-azure-aks-example/nginx-deployment.yml")
require.NoError(t, err)
// To ensure we can reuse the resource config on the same cluster to test different scenarios, we setup a unique
// namespace for the resources for this test.
// Note that namespaces must be lowercase.
namespaceName := strings.ToLower(random.UniqueId())
// Setup the kubectl config and context. Here we choose to use the defaults, which is:
// - HOME/.kube/config for the kubectl config file
// - Current context of the kubectl config file
options := k8s.NewKubectlOptions("", "../../examples/azure/kubeconfig", namespaceName)
k8s.CreateNamespace(t, options, namespaceName)
// ... and make sure to delete the namespace at the end of the test
defer k8s.DeleteNamespace(t, options, namespaceName)
// At the end of the test, run `kubectl delete -f RESOURCE_CONFIG` to clean up any resources that were created.
defer k8s.KubectlDelete(t, options, kubeResourcePath)
// This will run `kubectl apply -f RESOURCE_CONFIG` and fail the test if there are any errors
k8s.KubectlApply(t, options, kubeResourcePath)
// This will wait up to 10 seconds for the service to become available, to ensure that we can access it.
k8s.WaitUntilServiceAvailable(t, options, "nginx-service", 10, 20*time.Second)
// Now we verify that the service will successfully boot and start serving requests
service := k8s.GetService(t, options, "nginx-service")
endpoint := k8s.GetServiceEndpoint(t, options, service, 80)
// Setup a TLS configuration to submit with the helper, a blank struct is acceptable
tlsConfig := tls.Config{}
// Test the endpoint for up to 5 minutes. This will only fail if we timeout waiting for the service to return a 200
// response.
http_helper.HttpGetWithRetryWithCustomValidation(
t,
fmt.Sprintf("http://%s", endpoint),
&tlsConfig,
30,
10*time.Second,
func(statusCode int, body string) bool {
return statusCode == 200
},
)
}
However I get an error:
--- FAIL: TestK8sExample (777.42s)
=== RUN TestKubernetesBasicExample

Any help is appreciated
After my module generates kubeconfig file and I try to run "kubectl get nodes" it asks me to authenticate using browser:
$ kubectl get nodes
To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code XXXXXXXX to authenticate.
After I login I can see everything clearly. Maybe there is some option not to ask this prompt?
