Host-based routing in Kubernetes - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the host for routing in the Ingress rule.

Kubernetes

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
spec:
  rules:
  - host: [1]
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: example-service
            port:
              number: 80

💡 Hint

Common Mistakes

Using the service name instead of the host domain.

Putting the port number in the host field.

The host field specifies the domain name for host-based routing in the Ingress rule.

2fill in blank

medium

Complete the code to specify the path type for host-based routing.

Kubernetes

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
spec:
  rules:
  - host: example.com
    http:
      paths:
      - path: /app
        pathType: [1]
        backend:
          service:
            name: app-service
            port:
              number: 80

💡 Hint

Common Mistakes

Using unsupported path types like Suffix or Contains.

Confusing Exact with Prefix.

The pathType defines how the path is matched. Prefix means any path starting with /app will match.

Fix the error in the Ingress rule to correctly specify the backend service port.

Kubernetes

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: example-ingress
spec:
  rules:
  - host: example.com
    http:
      paths:
      - path: /api
        pathType: Prefix
        backend:
          service:
            name: api-service
            port:
              [1]

💡 Hint

Common Mistakes

Using just the port number without the 'number:' key.

Using 'port: 80' directly instead of nested object.

The port field must be an object with a number key specifying the port number.

4fill in blank

hard

Fill both blanks to create a host-based routing rule for two different hosts.

Kubernetes

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: multi-host-ingress
spec:
  rules:
  - host: [1]
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: service-one
            port:
              number: 80
  - host: [2]
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: service-two
            port:
              number: 80

💡 Hint

Common Mistakes

Using the same host for both rules.

Using service names instead of domain names.

Each host field must have a unique domain name for routing to different services.

5fill in blank

hard

Fill all three blanks to define an Ingress with host-based routing, path, and backend service port.

Kubernetes

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: full-ingress
spec:
  rules:
  - host: [1]
    http:
      paths:
      - path: [2]
        pathType: Prefix
        backend:
          service:
            name: full-service
            port:
              number: [3]

💡 Hint

Common Mistakes

Using a path without leading slash.

Using a string instead of a number for port.

Confusing host with service name.

The host is the domain name, path is the URL path prefix, and number is the backend service port.
