@Be The Code , Thank you for your question. You can make use of the NGINX Ingress default backend. The default backend is a service which handles all URL paths and hosts the nginx controller doesn't understand (i.e., all the requests that are not mapped with an Ingress).
Basically a default backend exposes two URLs:
/healthz that returns 200 / that returns 404
This blog post details how you can customize your NGINX Ingress default backend.
However, if you want a specific dummy backend application to be available on a specific path using NGINX Ingress, you can simply create a Deployment with the dummy application's container image, expose it using a Service and mention the Service in
spec.rules.http.paths.backend.service.name of your Ingress resource.
- Create a
Dockerfilewith the following content:
RUN echo "This is a dummy website" > /usr/share/nginx/html/index.html
- Build the container image using
docker build -t <your-repository>/<image-name>:<tag> /path/to/folder/with/Dockerfile
- Push the container image to your repository using
docker push <your-repository>/<image-name>:<tag>
- Create a Deployment using the image with
kubectl create deploy $DeploymentName --image <your-repository>/<image-name>:<tag> -n <namespace>
- Expose the Deployment using
kubectl expose deploy $DeploymentName --name $ServiceName --port 80
- Add the following under
spec.rulesof your Ingress resource.
When you have your final Service later, you can simply change
- http: paths: - path: <your-ingress-path> pathType: Prefix backend: service: name: $ServiceName port: number: 80
$ServiceNamewith the desired Service name and the
port.numberwith the appropriate value, using
kubectl edit ingress.
