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。
