问题描述
我一直试图使用Docker桌面在kubernetes和istio上在macOS上运行本地集群。我使用了bookinfo示例,一切运行正常。
我有自己的服务之一,无法运行它。我试着用邮递员打它,总是得到404。
我无法调试它,我可能只是缺少了一些东西或做了一些愚蠢的事情。 这些是我的Yaml文件
gateway.yaml

我已经通过使用Nodeport公开了该服务进行了测试,并且可以卷曲并获得相应的响应,但是由于无法正确配置入口,我犯了一些错误。
URL
我在下面使用我的URL。形成的网址为localhost/feed
export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="http2")].port}')
export SECURE_INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="https")].port}')
export INGRESS_HOST=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')
echo $INGRESS_HOST
echo $INGRESS_PORT
echo $SECURE_INGRESS_PORT
错误
[2020-08-22T01:01:05.088Z] "GET /feed HTTP/1.1" 404 - "-" "-" 0 19 29 22 "192.168.65.3" "PostmanRuntime/7.26.3" "e5705c53-6e70-9dbe-b831-764f9c7be63e" "localhost" "10.1.0.41:8080" outbound|8080||feed.default.svc.cluster.local 10.1.0.25:40654 10.1.0.25:8080 192.168.65.3:59050 - -
这里真的需要帮助。
解决方法
如果收到404错误,则表示已访问您的应用程序,但没有/feed
页面。
您可以更改应用程序以在该contextPath上提供所有内容,或者在VirtualService上进行重写:
http:
- match:
- uri:
exact: /feed
rewrite:
uri: /
route:
- destination:
host: feed
port:
number: 8080
