坚持让这个集成工作。
以下是我从头开始做的所有事情，所以如果这里没有列出它，则说明我还没有尝试过(我提前为冗长的命令系列道歉):
# create the resource group
az group create -l westus -n k8s-test
# create the azure container registery
az acr create -g k8s-test -n k8stestacr --sku Basic -l westus
# create the azure key vault and add a test value to it
az keyvault create --name k8stestakv --resource-group k8s-test -l westus
az keyvault secret set --vault-name k8stestakv --name SECRETTEST --value abc123
# create the azure kubernetes service
az aks create -n k8stestaks -g k8s-test --kubernetes-version=1.19.7 --node-count 1 -l westus --enable-managed-identity --attach-acr k8stestacr -s Standard_B2s
# switch to the aks context
az aks get-credentials -b k8stestaks -g k8s-test
# install helm charts for secrets store csi
helm repo add csi-secrets-store-provider-azure https://raw.githubusercontent.com/Azure/secrets-store-csi-driver-provider-azure/master/charts
helm install csi-secrets-store-provider-azure/csi-secrets-store-provider-azure --generate-name
# create role managed identity operator
az role assignment create --role "Managed Identity Operator" --assignee <k8stestaks_clientId> --scope /subscriptions/<subscriptionId>/resourcegroups/MC_k8s-test_k8stestaks_westus
# create role virtual machine contributor
az role assignment create --role "Virtual Machine Contributor" --assignee <k8stestaks_clientId> --scope /subscriptions/<subscriptionId>/resourcegroups/MC_k8s-test_k8stestaks_westus
# install more helm charts
helm repo add aad-pod-identity https://raw.githubusercontent.com/Azure/aad-pod-identity/master/charts
helm install pod-identity aad-pod-identity/aad-pod-identity
# create identity
az identity create -g MC_k8s-test_k8stestaks_westus -n TestIdentity
# give the new identity a reader role for AKV
az role assignment create --role "Reader" --assignee <TestIdentity_principalId> --scope /subscriptions/<subscription_id/resourceGroups/k8s-test/providers/Microsoft.KeyVault/vaults/k8stestakv
# allow the identity to get secrets from AKV
az keyvault set-policy -n k8stestakv --secret-permissions get --spn <TestIdentity_clientId>
这几乎就是az cli命令。到目前为止，一切都执行得很好，没有错误。我可以进入门户，查看MC_组的这些角色，TestIdentity组的只读角色用于机密等。
之后，文档要求您构建secretProviderClass.yaml:
apiVersion: secrets-store.csi.x-k8s.io/v1alpha1
kind: SecretProviderClass
metadata:
name: azure-kvname
spec:
provider: azure
parameters:
usePodIdentity: "true"
useVMManagedIdentity: "false"
userAssignedIdentityID: ""
keyvaultName: "k8stestakv"
cloudName: ""
objects: |
array:
- |
objectName: SECRETTEST
objectType: secret
objectVersion: ""
resourceGroup: "k8s-test"
subscriptionId: "<subscriptionId>"
tenantId: "<tenantId>"
还有podIdentityBinding.yaml:
apiVersion: aadpodidentity.k8s.io/v1
kind: AzureIdentity
metadata:
name: azureIdentity
spec:
type: 0
resourceID: /subscriptions/<subscriptionId>/resourcegroups/MC_k8s-test_k8stestaks_westus/providers/Microsoft.ManagedIdentity/userAssignedIdentities/TestIdentity
clientID: <TestIdentity_clientId>
---
apiVersion: aadpodidentity.k8s.io/v1
kind: AzureIdentityBinding
metadata:
name: azure-pod-identity-binding
spec:
azureIdentity: azureIdentity
selector: azure-pod-identity-binding-selector
然后应用它们:
# this one executes fine
kubectl apply -f k8s/secret/secretProviderClass.yaml
# this one does not
kubectl apply -f k8s/identity/podIdentityBinding.yaml
问题# 1
我得到最后一个:
unable to recognize "k8s/identity/podIdentityBinding.yaml": no matches for kind "AzureIdentity" in version "aadpodidentity.k8s.io/v1"
unable to recognize "k8s/identity/podIdentityBinding.yaml": no matches for kind "AzureIdentityBinding" in version "aadpodidentity.k8s.io/v1"
不确定为什么，因为helm install pod-identity aad-pod-identity/aad-pod-identity命令是成功的。然而，看着我的pod…
问题# 2我已经按照这些步骤三次了，每次问题都是一样的——aad-pod-identity-nmi-xxxxx不会启动:

我想我不确定这两个问题是否相关，我还没能让失败的Pod启动。
有什么建议吗?
如果您没有指定"Advanced"，那么它看起来与AKS为您选择的默认网络插件有关。网络选项:kubenet.
这个集成可以通过下面列出的kubenet完成:
https://azure.github.io/aad-pod-identity/docs/configure/aad_pod_identity_on_kubenet/
如果您正在创建一个新的集群，启用高级网络或添加--network-plugin azure标志和参数。
