The Tempest Kubernetes App enables management of Kubernetes applications and resources, with capabilities for both new deployments and importing existing resources for centralized management. For detailed information about each resource, see the Resources section below.

​
Authentication

Currently supports public Kubernetes clusters via kubeconfig. Support for private clusters coming soon.

​
Kubeconfig Authentication

  • Cluster API must be publicly accessible (typical for GKE and EKS clusters)
  • Dedicated service account with long-lived token
1

Create Service Account

apiVersion: v1
kind: ServiceAccount
metadata:
  name: <service_account_name>
  namespace: <your_namespace>
Apply with: kubectl apply -f sa.yaml
2

Create Service Account Token

apiVersion: v1
kind: Secret
type: kubernetes.io/service-account-token
metadata:
  name: <token_name>
  namespace: <your_namespace>
  annotations:
    kubernetes.io/service-account.name: <service_account_name>
Apply with: kubectl apply -f sa_token.yaml
3

Bind to Cluster Role

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: <service_account_name>
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: <service_account_name>
    namespace: <your_namespace>
Apply with: kubectl apply -f crb.yaml
4

Get Token

Retrieve token: kubectl get secret <token_name> -o jsonpath='{.data.token}' | base64 --decode
5

Create Kubeconfig

apiVersion: v1
clusters:
  - cluster: { your_cluster_information }
    name: <your_cluster_name>
contexts:
  - context:
      cluster: <your_cluster_name>
      user: <service_account_name>
    name: <your_cluster_name>
current-context: <your_cluster_name>
kind: Config
preferences: {}
users:
  - name: <service_account_name>
    user:
      token: <token_data>
