# =============================================================================
# UpCloud Workload Cluster
# =============================================================================
# A lean UCS cluster for running application workloads. No managed data
# services — those live on the platform cluster. ArgoCD (on the platform
# cluster) deploys apps to this cluster via the app-of-apps pattern.
#
# Platform components deployed by deploy-workload.sh:
# nginx-ingress, cert-manager, external-dns, external-secrets, alloy
#
# Usage:
# tofu init && tofu plan && tofu apply
# ./sync-tofu-outputs.sh --env upcloud-workload
# ./deploy-workload.sh --env upcloud-workload

Fetch (or reuse) a kubeconfig for the given cluster.
Platform is read from the cluster prefix (<platform>-...).
Env type must be supplied explicitly — it is no longer inferred
from the cluster name, so names like 'upc-forte-group' work.

Provision a Kubernetes cluster using OpenTofu. Provision a Kubernetes cluster using OpenTofu.
Mirrors bootstrap.sh convention: cluster = <platform>-<env> Cluster name is opaque — platform is read from its prefix
(<platform>-...), env is taken from --envtype.
Clusters: aks-dev | aks-prod | eks-dev | eks-prod Platforms (inferred from cluster prefix):
gke-dev | gke-prod | upc-dev | upc-prod aks | eks | gke | upc
upc-forte-group
<platform>-workload (for workload clusters) Env types (required via --envtype):
dev Platform cluster, development
prod Platform cluster, production
workload Lean cluster for application workloads (no managed data
services — those run on the platform cluster)
Options: Options:
--plan Plan only, don't apply --envtype <type> dev | prod | workload (required)
--destroy Destroy the cluster (use teardown-cluster.sh instead) --plan Plan only, don't apply
--auto Skip confirmation prompts --destroy Destroy the cluster (use teardown-cluster.sh instead)
-h, --help Show this help --auto Skip confirmation prompts
-h, --help Show this help
Examples: Examples:
$0 aks-dev $0 aks-dev --envtype dev
$0 eks-prod --plan $0 eks-prod --envtype prod --plan
$0 upc-dev --auto $0 upc-forte-group --envtype prod --auto
