GatewayPortNotDefinedOnService
消息名称 | GatewayPortNotDefinedOnService |
消息代码 | IST0162 |
描述 | Gateway port not exposed by service |
等级 | Warning |
当 Gateway(通常是 istio-ingressgateway
) 提供的端口与网关实例关联的 Kubernetes 服务(Service) 定义的端口不匹配时,GatewayPortNotDefinedOnService
消息将会出现。
例如,您的配置定义如下:
# 端口定义错误的 Gateway
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
name: istio-ingressgateway
spec:
selector:
istio: ingressgateway
servers:
- port:
number: 80
name: http
protocol: HTTP
hosts:
- "*"
- port:
number: 8004
name: http2
protocol: HTTP
hosts:
- "*"
---
# 默认的网关 Service
apiVersion: v1
kind: Service
metadata:
name: istio-ingressgateway
spec:
selector:
istio: ingressgateway
ports:
- name: status-port
port: 15021
protocol: TCP
targetPort: 15021
- name: http2
port: 80
protocol: TCP
targetPort: 8080
- name: https
port: 443
protocol: TCP
targetPort: 8443
在此示例中,GatewayPortNotDefinedOnService
消息出现, 因为此配置使用了端口 8004
,但默认的 IngressGateway
(名称为 istio-ingressgateway
)只定义了目标端口 15021、8080 和 8443。
要解决此问题,请更改网关配置以使用工作负载上的有效端口,然后重试。
以下是已更正的示例:
# 端口定义正确的 Gateway
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
name: istio-ingressgateway
spec:
selector:
istio: ingressgateway
servers:
- port:
number: 8080
name: http2
protocol: HTTP
hosts:
- "*"
- port:
number: 8443
name: https
protocol: HTTP
hosts:
- "*"
