ServiceEntryAddressesRequired

消息名称	ServiceEntryAddressesRequired
消息代码	IST0134
描述	Virtual IP addresses are required for ports serving TCP (or unset) protocol when ISTIO_META_DNS_AUTO_ALLOCATE is not set on a proxy
等级	Warning

当 ServiceEntry 的 protocol 字段未设置、设置为 TCP 或未定义 addresses 时，会出现此消息。

示例

您将收到以下消息：

Warning [IST0134] (ServiceEntry service-entry.default serviceentry.yaml:13) ServiceEntry addresses are required for this protocol.

当集群的 ServiceEntry 未设置 protocol 且缺少 addresses 时：

apiVersion: networking.istio.io/v1
kind: ServiceEntry
metadata:
  name: service-entry
  namespace: default
spec:
  hosts:
    - 'istio.io'
  exportTo:
    - "."
  ports:
    - number: 443
      name: https
  location: MESH_EXTERNAL
  resolution: DNS

这种分析器的另一个例子是 ServiceEntry 设置了 protocol: TCP 但缺少 addresses 时：

apiVersion: networking.istio.io/v1
kind: ServiceEntry
metadata:
  name: service-entry
  namespace: default
spec:
  hosts:
    - 'istio.io'
  exportTo:
    - "."
  ports:
    - number: 443
      name: https
      protocol: TCP
  location: MESH_EXTERNAL
  resolution: DNS

如何修复

请确保在 protocol 未设置或设置为 TCP 时，在 ServiceEntry 中设置 addresses。如果未设置 addresses，则将匹配 ServiceEntry 所定义的端口上的所有流量，与主机无关。
