ASP.Net Core 2.2 Kubernetes Ingress: Resolving 'Not Found' Static Content for Custom Path

ASP.Net Core 2.2 Kubernetes Ingress: Resolving ‘Not Found’ Static Content for Custom Path

In the world of data science, the ability to manage and deploy applications efficiently is crucial. Kubernetes, a powerful open-source platform for automating deployment, scaling, and management of containerized applications, is a popular choice among data scientists. However, when working with ASP.Net Core 2.2 on Kubernetes, you may encounter an issue where static content for a custom path is not found. This blog post will guide you through the steps to resolve this issue.

Understanding the Issue

When deploying an ASP.Net Core 2.2 application on Kubernetes, you might encounter a ‘Not Found’ error for static content when using a custom path. This issue often arises due to incorrect configuration of the Kubernetes Ingress controller or the ASP.Net Core application.

Prerequisites

Before we dive into the solution, ensure you have the following:

• A Kubernetes cluster up and running.
• Helm installed on your machine.
• Basic understanding of Kubernetes Ingress and ASP.Net Core.

Step 1: Install and Configure NGINX Ingress Controller

The first step is to install the NGINX Ingress Controller. This can be done using Helm:

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm install my-release ingress-nginx/ingress-nginx

Once installed, you need to configure the Ingress Controller to handle the custom path for your static content.

Step 2: Configure the Ingress Resource

The next step is to configure the Ingress resource. This is where you define the rules for traffic routing. Here’s a sample configuration:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: my-ingress
spec:
  rules:
  - host: myapp.mydomain.com
    http:
      paths:
      - pathType: Prefix
        path: "/mypath"
        backend:
          service:
            name: my-service
            port:
              number: 80

In this configuration, traffic to ‘myapp.mydomain.com/mypath’ is routed to the service ‘my-service’ on port 80.

Step 3: Configure ASP.Net Core to Serve Static Files

ASP.Net Core does not serve static files by default. You need to configure it to do so. This can be done in the Startup.cs file:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseStaticFiles(); // Enable static files

    app.UseRouting();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllers();
    });
}

Step 4: Configure Static File Options

If your static files are located in a custom path, you need to specify this in the UseStaticFiles method:

app.UseStaticFiles(new StaticFileOptions
{
    FileProvider = new PhysicalFileProvider(
        Path.Combine(Directory.GetCurrentDirectory(), "mypath")),
    RequestPath = "/mypath"
});

This configuration tells ASP.Net Core to serve static files from the ‘mypath’ directory.

Step 5: Test Your Configuration

Finally, test your configuration by accessing your static content via the custom path. If everything is set up correctly, you should no longer see the ‘Not Found’ error.

Conclusion

In this post, we’ve walked through the steps to resolve the ‘Not Found’ static content issue when deploying an ASP.Net Core 2.2 application on Kubernetes. By correctly configuring the Kubernetes Ingress controller and the ASP.Net Core application, you can ensure your static content is served correctly.

Remember, the key to successful deployment lies in understanding the tools you’re working with and configuring them correctly. Keep exploring, keep learning, and keep deploying!
