This zip can be used to deploy a wordpress instance with a mysql-galera cluster on kubernetes using terraform.
First of all install terraform on your computer, minikube and helm.
After that you can
$ terrraform init
$ terraform plan
$ terraform apply
The zip contains the terraform.tf, and the values for wordpress and mysql-galera chart.
You can define your self password customizing and creating a kubernetes secret, or simply passing it in clear text on vars (no safe dude)
