Kubernetes Ingress Configuration

1. Create a Kubernetes Secret

First, you need to create a Kubernetes secret to store your TLS certificate and private key. You can do this using the following command:

1kubectl create secret tls my-tls-secret --cert=/path/to/your/cert.crt --key=/path/to/your/key.key

Replace /path/to/your/cert.crt and /path/to/your/key.key with the actual paths to your certificate and private key files.

2. Configure Ingress Resource

Next, you need to create or modify your Ingress resource to use the TLS secret. Here's an example YAML configuration:

1apiVersion: networking.k8s.io/v1
2kind: Ingress
3metadata:
4  name: my-ingress
5  annotations:
6    nginx.ingress.kubernetes.io/rewrite-target: /
7spec:
8  tls:
9    - hosts:
10        - your-domain.com
11      secretName: my-tls-secret
12  rules:
13    - host: your-domain.com
14      http:
15        paths:
16          - path: /
17            pathType: Prefix
18            backend:
19              service:
20                name: your-service
21                port:
22                  number: 80

Replace your-domain.com with your actual domain, your-service with the name of your backend service, and adjust the port number as needed.

3. Apply the Ingress Configuration

Apply the Ingress configuration using kubectl:

1kubectl apply -f your-ingress-file.yaml

4. Verify the Ingress Setup

Check that the Ingress resource has been created successfully and is using the TLS settings:

1kubectl get ingress my-ingress -o yaml
