## Prepare the base image
First, prepare variables to your environment
```shell
export TF_VAR_hcloud_token=KEY
``` ```
```bash Terraform will run the VM in recovery mode, replace the base image and take a snapshote. Do not run terraform destroy after. It will delete the snapshot.
kubectl -n kube-system create secret generic hcloud --from-literal=network= --from-literal=token=
```shell
make prepare-image
```
## Install control plane
Generate the default talos config
```shell
make create-config
```
open config file **terraform.tfvars** and add params
```hcl
# counts and type of kubernetes master nodes
controlplane = {
count = 1,
type = "cpx11"
}
# regions to use
regions = ["nbg1", "fsn1", "hel1"]
# counts and type of worker nodes by redion
instances = {
"nbg1" = {
web_count = 1,
web_instance_type = "cx11",
worker_count = 1,
worker_instance_type = "cx11",
},
"fsn1" = {
web_count = 1,
web_instance_type = "cx11",
worker_count = 1,
worker_instance_type = "cx11",
}
"hel1" = {
web_count = 1,
web_instance_type = "cx11",
worker_count = 1,
worker_instance_type = "cx11",
}
}
```
And deploy the kubernetes master nodes
```shell
make create-controlplane
```
Then deploy all other instances
```shell
make create-infrastructure
``` ```
