[英]ASP.Net Core 2.2 Kubernetes Ingress: not found static content for custom path
I have the following ingress.yml:我有以下 ingress.yml:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress
namespace: default
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/ssl-redirect: "false"
nginx.ingress.kubernetes.io/rewrite-target: /$2
labels:
app: ingress
spec:
rules:
- host:
http:
paths:
- path: /apistarter(/|$)(.*)
backend:
serviceName: svc-aspnetapistarter
servicePort: 5000
- path: //apistarter(/|$)(.*)
backend:
serviceName: svc-aspnetapistarter
servicePort: 5000
After deploying my ASP.Net Core 2.2 API application and navigate to http://localhost/apistarter/
, browser debugger console shows errors loading the static content and Javascripts.部署我的 ASP.Net Core 2.2 API 应用程序并导航到http://localhost/apistarter/
,浏览器调试器控制台显示加载静态内容和 Javascript 的错误。 In addition, navigating to http://localhost/apistarter/swagger/index.html
results in此外,导航到http://localhost/apistarter/swagger/index.html
结果
Fetch error Not Found /swagger/v2/swagger.json
I am using the SAME ingress for multiple micro-services using different path prefix.我对使用不同路径前缀的多个微服务使用相同的入口。 It is running on my local kubernetes cluster using microk8s.它使用 microk8s 在我的本地 kubernetes 集群上运行。 Not on any cloud provider yet.还没有在任何云提供商上。 I have checked out How to configure an ASP.NET Core multi microservice application and Azure AKS ingress routes so that it doesn't break resources in the wwwroot folder and https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/proxy-load-balancer?view=aspnetcore-2.1 but none of these helps.我已经查看了如何配置 ASP.NET Core 多微服务应用程序和 Azure AKS 入口路由,以便它不会破坏 wwwroot 文件夹和https://docs.microsoft.com/en-us/aspnet/core 中的资源/host-and-deploy/proxy-load-balancer?view=aspnetcore-2.1但这些都没有帮助。
