Deploying Grafana to Openshift With Terraform

Infrastructure as code increases productivity and transparency. By storing the architecture configuration in version control, changes can be compared to the previous state, and the history gets visible and traceable. Terraform is an open source command line tool which codifies APIs into declarative configuration files. In this tutorial, Terraform is used to deploy Grafana to OpenShift, including the creation of a service, an external route, the deployment configuration, and persistent volumes.
