无法作为ServiceAccount进行部署

Question

我试图访问另一个名称空间中的部署，并具有以下ServiceAccount、ClusterRole和ClusterRoleBinding

apiVersion: v1
kind: ServiceAccount
metadata:
  name: tekton-triggers-example-sa
  namespace: tekton-pipelines
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
    name: tekton-pipeline-sa
rules:
    - apiGroups: [""]
      resources: ["secrets", "services", "deployments", "pods"]
      verbs: ["get", "watch", "list", "create", "delete"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
    name: tekton-pipeline-permissions
    namespace: tekton-pipelines
subjects:
    - kind: ServiceAccount
      name: tekton-triggers-example-sa
      namespace: tekton-pipelines
roleRef:
    apiGroup: rbac.authorization.k8s.io
    kind: ClusterRole
    name: tekton-pipeline-sa

有了这个，我可以得到除了deployments以外的一切

kubectl auth can-i get secrets --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
yes
kubectl auth can-i get services --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
yes
kubectl auth can-i get deployments --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
no
kubectl auth can-i get pods --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
yes

如果我删除绑定，我什么也得不到，这是有道理的

kubectl delete -f rbac/binding.yaml 
clusterrolebinding.rbac.authorization.k8s.io "tekton-pipeline-permissions" deleted

kubectl auth can-i get secrets --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
no
kubectl auth can-i get services --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
no
kubectl auth can-i get deployments --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
no
kubectl auth can-i get pods --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
no

如果我再次应用它，我可以访问除了deployments以外的所有东西

kubectl apply -f rbac/binding.yaml 
clusterrolebinding.rbac.authorization.k8s.io/tekton-pipeline-permissions created
kubectl auth can-i get secrets --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
yes
kubectl auth can-i get services --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
yes
kubectl auth can-i get deployments --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
no
kubectl auth can-i get pods --as=system:serviceaccount:tekton-pipelines:tekton-triggers-example-sa -n anxiety-app 
yes

因此，在我看来，绑定对于除deployments之外的所有资源都是有效的。

谁知道我错了什么，为什么我不能进入部署？

Answer 1

您的ClusterRole应该是：

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: tekton-pipeline-sa
rules:
- apiGroups: [""]
  resources: ["secrets", "services", "pods"]
  verbs: ["get", "watch", "list", "create", "delete"]
- apiGroups: ["apps"]
  resources: ["deployments"]
  verbs: ["get", "watch", "list", "create", "delete"]

一个部署将有一些apiVersion: apps/v1。它属于apiGroups apps。这里有豆荚、秘密或服务的地方将其设置为v1，因此在appGroups ""中。
