Terraform Example

This repository showcases how to setup Terraform to manage your Civo Kubernetes cluster and install Helm Charts.

File overview

• provider.tf -- the Terraform providers used within this respository
• output.tf -- this file lists which information to provide after running terraform apply
• cluster.tf -- the Civo Kubernetes cluster resource
• variables.tf -- the variables that will be passed into the provider.tf and cluster.tf -- you can also add additional variables to be passed into the helm_release files
• ./charts -- the custom Helm Charts will be put into this directory
• helm_release_nginx.tf -- refers to a custom Helm Chart
• helm_release_prometheus.tg -- installs the Prometheus stack operator

Getting started

Prerequisites

• [A Civo Account]()
• Terraform installed locally

Run the following command to initialise the provider:

terraform init

List the resources that will be installed and managed by terraform:

terraform plan

Create those resources

terraform apply

Additionally, you can list the state that Terraformn is amanging through:

terraform state list

To remove any state from terraform, use:

terraform state rm <<name of the state that you want to remove>>

To modify the resources in the .tf files, use the terraform console:

terraform console

and then look for the object e.g.

data.civo_kubernetes_cluster.cluster
