Having issues configuring SSL termination in my Kubernetes cluster. Attempting to figure out best place for this to happen.
I have been able to get it working following the instructions listed here and then updating the ingress controller service to include the SSL certificate details using service.beta.kubernetes.io/aws-load-balancer-ssl-cert annotation:
kind: Service
apiVersion: v1
metadata:
name: ingress-nginx
namespace: ingress-nginx
labels:
app: ingress-nginx
annotations:
service.beta.kubernetes.io/aws-load-balancer-proxy-protocol: '*'
service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:...
spec:
type: LoadBalancer
selector:
app: ingress-nginx
ports:
- name: https
port: 443
targetPort: 80
I then have ingress rules and services setup similar to:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: app1
annotations:
kubernetes.io/ingress.class: nginx
spec:
rules:
- host: app1.foo.bar
http:
paths:
- backend:
serviceName: app1
servicePort: 80
---
apiVersion: v1
kind: Service
metadata:
name: app1
spec:
type: LoadBalancer
ports:
- name: http
port: 80
targetPort: 80
selector:
app: app1
---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: app1
spec:
template:
metadata:
labels:
app: app1
spec:
containers:
- image: nginx
name: nginx
ports:
- containerPort: 80
When going to app1.foo.bar
I can see that:
- http requests are redirected to https
- the SSL certificate is correctly applied
Originally I was trying to apply the certificate to my individual app services. I could see the certificate being applied to the ELB in AWS but wasn't being passed through. So my question is:
Is this the correct configuration or is there a better solution?
Thank you :)
