NoMatchingWorkloadsFound

AuthorizationPolicy 资源的选择器匹配不到任何 Pod 时,会出现此消息。

示例

当集群包含以下 AuthorizationPolicy 时:

apiVersion: security.istio.io/v1
kind: AuthorizationPolicy
metadata:
  name: httpbin-nopods
  namespace: httpbin
spec:
  selector:
    matchLabels:
      app: bogus-label # 标签有误,没有匹配的工作负载
      version: v1
  rules:
    - from:
        - source:
            principals: ["cluster.local/ns/default/sa/curl"]
        - source:
            namespaces: ["httpbin"]
      to:
        - operation:
            methods: ["GET"]
            paths: ["/info*"]
        - operation:
            methods: ["POST"]
            paths: ["/data"]
      when:
        - key: request.auth.claims[iss]
          values: ["https://accounts.google.com"]

您会收到此消息:

Warning [IST0127] (AuthorizationPolicy httpbin-nopods.httpbin) No matching workloads for this resource with the following labels: app=bogus-label,version=v1

在这个样例中,AuthorizationPolicy 资源 httpbin-nopods 需要绑定到包含 app=bogus-label 标签的 Pod 上,但是其不存在。

如何修复

  • 修改选择器 selector 以选择存在的 Pod
  • 修改特定 Pod 的标签以匹配此资源的选择器
