Reference

Installation:

Generate certs manually:

$ mkdir certs
$ openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./certs/tls-key.key -out -/certs/tls-cert.crt

Create k8s secret for certs:

$ kubectl create secret tls tls-certificate --key ./certs/tls-key.key --cert ./certs/tls-cert.crt
$ kubectl label secret tls-certificate app=wpdemo

Create Resources (Services, Ingress, Deployments ...):

$ kubectl apply -f secrets.yaml
$ kubectl apply -f db-tier-deployment.yaml
$ kubectl apply -f app-tier-deployment.yaml
$ kubectl apply -f nginx-ingress.yaml

Create local host for minikube.io domain (or edit it)

  • Adds minikube.io to /etc/hosts file with Minikube cluster ip
  • Example: 192.168.99.100 minikube.io

To get cluster IP:

$ minikube ip //Get Kubernetes Cluster IP

Test it!

$ minikube dashboard //Check cluster resources

Access https://minikube.io
