Ingress Configuration

This example builds on Basic Deployment by adding ingress configuration to expose your application to traffic outside of the cluster.

What You'll Learn​

In this lesson, you'll learn:

  • How to expose your application to the internet
  • Ingress configuration options
  • Hostname patterns and DNS
  • Visibility (public vs private)
  • Authentication (OIDC)

What Gets Created​

In addition to the resources from Basic Deployment, the platform creates:

  • HTTPRoute (Gateway API) or VirtualService (Istio)
  • Gateway configuration
  • DNS entries (automatic)
  • TLS certificates (automatic)

What Changed​

Added the spec.networking.ingress section:

apiVersion: meta.p6m.dev/v1alpha1
kind: PlatformApplication
metadata:
  name: demo-http-echo
  namespace: demo-http-echo
  labels:
    p6m.dev/app: demo-http-echo
spec:
  deployment:
    image: mendhak/http-https-echo:31
    ports:
      - port: 8080
        protocol: http
    readinessProbe:
      port: 8080
      path: /
# NEW
  networking:
    ingress:
      enabled: true
      path: /
      gateway: public-open
# NEW

Gateway Selection​

If you do not specify a gateway (spec.networking.ingress.gateway), the platform will use the one assigned by the Administrator as the Environment default.

Check out the Gateway Selection Details for more information on choosing the right gateway for your use case.

Deploy Steps​

ArgoCD automatically updates to your PlatformApplication after the Platform Dispatch Action to update your .platform repository is run.

For more information on setting up ArgoCD for Platform Applications, see the ArgoCD Deployment Tutorial.

Find Your Application's URL​

To find your application's URL, use ArgoCD to find the HTTPRoute (spec.hostnames[]) or VirtualService (spec.hosts[]) created for your application, then check the spec appropriate field.

Test Access​

Once DNS has propagated, test access from outside the cluster using curl.

curl https://demo-http-echo.eks.us-east-2.aws.dev.ybor-studio.p6m.run
# {
#   "path": "/",
#   "headers": {
#     "host": "demo-http-echo.eks.us-east-2.aws.dev.ybor-studio.p6m.run",
# ...
#   "os": {
#     "hostname": "demo-http-echo-b994d5d67-gpdxz"
#   },
#   "connection": {}
# }

You can see the pod name in the response, showing that the request did go where we wanted.

Custom Hostnames​

PlatformApplications can be configured with custom hostnames by adding hosts to spec.networking.ingress.hostnames[]. Since this requires Certificates to be configured as well, check out our specific guide here (Coming Soon).

Configuration Options​

  • Visibility (PublicIP / PrivateIP)
  • OIDC authentication
  • Custom hostnames
  • Path-based routing
  • Gateway selection
