Kubernetes

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

Prerequisites

Generate Kubeconfig for Tempest

Create Service Account

apiVersion: v1
kind: ServiceAccount
metadata:
  name: <service_account_name>
  namespace: <your_namespace>

Apply with: kubectl apply -f sa.yaml

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

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

Get Token

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

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>
