KubeOne on GCP

cd gcp

Now configure a service account as described on this page: https://docs.kubermatic.com/kubeone/v1.6/guides/credentials/#environment-variables-3

export GOOGLE_CREDENTIALS=$(cat ./.env/k1-cluster-provisioner-sa-key.json)

Now we are set and can run the Terraform installation:

cd terraform
terraform init

vim terraform.tfvars ### TODO ADJUST your vars
terraform apply -var=control_plane_target_pool_members_count=1

Here you can find the reason why we use the terraform apply in a different way: https://docs.kubermatic.com/kubeone/v1.4/guides/using_terraform_configs/#terraform-apply-1

Now lets run it:

terraform output --json

The output shows you the source input for the cluster bootstrapping by kubeone

cd ..
kubeone apply -m kubeone.yaml -t ./terraform --verbose

Ensure HA by register all Control Planes

cd terraform
terraform apply
cd ..
kubeone apply -m kubeone.yaml -t ./terraform --verbose

New we cann upgrade to a new K8s version check kubeone_update_1.yaml:

cd ..
kubeone apply -m kubeone_update_1.yaml -t ./terraform --verbose

If you want to apply final update and chart installation, check kubeone_update_final.yaml:

#enable autoscaler
kubeone apply -m kubeone_update_final.yaml -t ./terraform --verbose

# add preemptible node pool
export KUBECONFIG=gcp-example-2023-kubeconfig
kubectl apply -f machines/
