无法从webhook容器创建TaskRun/PipeLineRun

Question

我正在尝试创建一个PipeLineRun/PipeLineRun，从一个大洲内部监听一个webhook并运行tkn --但我需要RBAC权限。我尝试将角色绑定角色:tekton-pipelines controller设置为默认服务帐户：

apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: webhook
  namespace: tekton-pipelines
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: Role
  name: tekton-pipelines-controller
subjects:
  - kind: ServiceAccount
    name: default
    namespace: default

但我还是不能这样做：

kubectl auth can-i create taskrun -n default --as=system:serviceaccount:default:default

no

我还尝试为资源创建一个角色：

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  name: webhook-create-taskrun
  namespace: tekton-pipelines
rules:
  - apiGroups: ["tekton.dev/v1beta1"]
    resources: ["taskrun"]
    verbs: ["get", "create", "list"]
# [ delete deletecollection get list patch create update watch ]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: webhook-create-taskrun
  namespace: tekton-pipelines
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: Role
  name: webhook-create-taskrun
subjects:
  - kind: ServiceAccount
    name: default
    namespace: default

不幸的是，仍然无法访问

我还在tekton- RoleBindings中的所有管道中查找了任何"taskrun“，但什么也没有找到

        ns := "tekton-pipelines"
    rbacClientSet := clientSet.RbacV1()
    rolebindings, _ := rbacClientSet.RoleBindings(ns).List(context.Background(), metav1.ListOptions{})

    for _, element := range rolebindings.Items {
        fmt.Println(element)
    }

您的ServiceAccount应该被授予类似于EventListener的权限(Tekton触发器)。

您可以在那里找到一个示例角色：https://github.com/tektoncd/triggers/blob/main/config/200-clusterrole.yaml#L64-L87：

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: tekton-triggers-eventlistener-roles
  labels:
    app.kubernetes.io/instance: default
    app.kubernetes.io/part-of: tekton-triggers
rules:
  - apiGroups: ["triggers.tekton.dev"]
    resources: ["eventlisteners", "triggerbindings", "triggertemplates", "triggers"]
    verbs: ["get", "list", "watch"]
  - apiGroups: [""]
    resources: ["configmaps"]
    verbs: ["get", "list", "watch"]
  - apiGroups: ["tekton.dev"]
    resources: ["pipelineruns", "pipelineresources", "taskruns"]
    verbs: ["create"]
  - apiGroups: [""]
    resources: ["serviceaccounts"]
    verbs: ["impersonate"]
  - apiGroups: ["policy"]
    resources: ["podsecuritypolicies"]
    resourceNames: ["tekton-triggers"]
    verbs: ["use"]

您使用的(tekton-pipelines PipelineRuns )不是用来创建控制器的。

您尝试自己编写的代码允许创建TaskRuns，但您仍然缺少PipelineRuns。

如果您正在实现自己的触发器，则可能不需要完整的tekton- triggers eventlistener-roles权限。创建流水线运行可能就足够了。
