Generate Auth TOKEN for your Kubernetes cluster

• create the following kubestorm.yaml

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: kubestorm-role
rules:
  - apiGroups: ["", "extensions", "apps", "batch", "events", "resourcequotas"]
    resources: ["*"]
    verbs: ["list", "watch", "get"]
---
apiVersion: v1
kind: ServiceAccount
metadata:

  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: kubestorm-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: kubestorm-role
subjects:
  - kind: ServiceAccount
    name: kubestorm-user
    namespace: kube-system

kubectl apply -f kubestorm.yaml

Get server URL

export CURRENT_CONTEXT=$(kubectl config current-context) && export CURRENT_CLUSTER=$(kubectl config view -o go-template="{{\$curr_context := \"$CURRENT_CONTEXT\" }}{{range .contexts}}{{if eq .name \$curr_context}}{{.context.cluster}}{{end}}{{end}}") && echo $(kubectl config view -o go-template="{{\$cluster_context := \"$CURRENT_CLUSTER\"}}{{range .clusters}}{{if eq .name \$cluster_context}}{{.cluster.server}}{{end}}{{end}}")

Get serverCADataString

echo $(kubectl get secret -n kube-system -o go-template='{{index .data "ca.crt" }}' $(kubectl get sa kubestorm-user -n kube-system -o go-template="{{range .secrets}}{{.name}}{{end}}"))

Get token

echo $(kubectl get secret -n kube-system -o go-template='{{index .data "token" }}' $(kubectl get sa kubestorm-user -n kube-system -o go-template="{{range .secrets}}{{.name}}{{end}}")) | base64 --decode

CRUD cluster auth

Execute the following script to add cluster

export CLUSTER_NAME="foo"

# replace with actual URL of kubestorm
./scripts/add_cluster.sh "${CLUSTER_NAME}" http://localhost:8080

# get auth
curl --location --request GET "http://localhost:8080/api/v1/auth/${CLUSTER_NAME}"

# delete
curl --location --request DELETE "http://localhost:8080/api/v1/auth/${CLUSTER_NAME}"

GET Kubernetes resources from a cluster

curl --location --request GET "http://localhost:8080/api/v1/resources?cluster=${CLUSTER_NAME}&type=nodes"
