Terraform¶
With Terraform we can create services on the cluster.
Now we can connect terraform to the Cluster. First we need to get the config for the cluster with kubectl.
kubectl config view --minify --flatten
This will give us the config to connect to the cluster. We need to add this to the terraform file.
Fill these values in the terraform.tfvars file.
host = clusters.cluster.server
client_certificate = users.user.client-certificate
client_key = users.user.client-key
cluster_ca_certificate = clusters.cluster.certificate-authority-data
# Example:
host = "https://127.0.0.1:32768"
client_certificate = "LS0tLS1CRUdJTiB..."
client_key = "LS0tLS1CRUdJTiB..."
cluster_ca_certificate = "LS0tLS1CRUdJTiB..."
Example: Homer¶
In the homer folder we have an example of how to use terraform to create a service on the cluster.
First we need to declare the terraform.tfvars file. We can copy the terraform.tfvars.example file and fill in the values.
cp terraform.tfvars.example terraform.tfvars
vim terraform.tfvars
Then we can run terraform.
terraform apply
Config¶
The configmap.tf file holds the configmap of the service. It reads the homer-config.yaml file in the folder.
The deployment.tf file holds the deployment of the service. It mounts the configmap as a volume.
The terraform.tfvars file holds the variables for the connection to the cluster.
The provider.tf file holds the connection to the cluster.
The service.tf file holds the service of the service.
