根据标题，我按照文档进行了集成。

我可以部署nginx.yaml并在大约 70 秒后打印出秘密：

kubectl exec -it nginx -- cat /mnt/secrets-store/secret1

现在我正在尝试将其应用于 PostgreSQL 部署进行测试，我从 Pod 获得以下信息description：

  Warning  FailedMount             3s    kubelet                  MountVolume.SetUp failed for volume "secrets-store01-inline" : rpc error: code = Unknown desc = failed to mount secrets store objects for pod staging/postgres-deployment-staging-69965ff767-8hmww, err: rpc error: code = Unknown desc = failed to mount objects, error: failed to get keyvault client: failed to get key vault token: nmi response failed with status code: 404, err: <nil>

从nmi logs：

E0221 22:54:32.037357       1 server.go:234] failed to get identities, error: getting assigned identities for pod staging/postgres-deployment-staging-69965ff767-8hmww in CREATED state failed after 16 attempts, retry duration [5]s, error: <nil>. Check MIC pod logs for identity assignment errors

不知道为什么，因为我基本上将设置nignx.yaml从postgres.yaml. 他们来了：

我的监督......aadpodidbinding应该是template:：

生成的 YAML 应该是：

在规范中添加模板将解决问题，在 deployment.yaml 文件的模板标签部分中使用标签“aadpodidbinding：“您的天蓝色 pod 身份选择器”

示例部署文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
        aadpodidbinding: azure-pod-identity-binding-selector
    spec:
      containers:
        - name: nginx
          image: nginx
          env:
          - name: SECRET
            valueFrom:
              secretKeyRef:
                name: test-secret
                key: key
          volumeMounts:
            - name: secrets-store-inline
              mountPath: "/mnt/secrets-store"
              readOnly: true
      volumes:
        - name: secrets-store-inline
          csi:
            driver: secrets-store.csi.k8s.io
            readOnly: true
            volumeAttributes:
              secretProviderClass: dev-1spc
