Adding TLS

Generate self-signed certificate

openssl req -x509 -newkey rsa:4096 -sha256 -nodes -keyout tls.key -out tls.crt -subj "/CN=example.com" -days 365

kubectl create secret tls example-com-tls --cert=tls.crt --key=tls.key --dry-run=client -oyaml > ingress/example-com-tls.yaml

Checking tls setup in the ingress controller manifest, ingress.yaml

spec:
  tls:
   - secretName: example-com-tls
     hosts:
       - example.com

Apply changes

kubectl apply -f ingress

Setup example.com for making it possible to be run locally

echo "$(minikube ip) example.com" | sudo tee -a /etc/hosts

Checking changes

curl --insecure https://example.com 

Clean up

Delete artifacts and workloads

kubectl delete -f ingress

Remove entry in the /etc/hosts, if it was added as last line

sudo sed '$d' --in-place /etc/hosts
