在 terraform 中授予事件查看权限

Question

我们有由 Rancher 管理的本地 Kubernetes 集群，我们使用 Terraform 在代码中进行配置。但是，我似乎无法授予我的组 devops 查看集群中事件的权限。

这些是角色和角色绑定：

resource "rancher2_role_template" "events-view" {
  name = "Cluster Events View"
  description = "Terraform role template to see cluster events"
  rules {
    api_groups     = ["*"]
    resources      = ["events"]
    verbs          = ["get", "watch"]
  }
}

resource "rancher2_cluster_role_template_binding" "events-view" {
  name = "events-view"
  cluster_id = rancher2_cluster.rancher_cluster.id
  role_template_id = rancher2_role_template.events-view.id
  group_principal_id = lookup(var.projects["devops"] , "ldap_cn")
  depends_on = [
    rancher2_role_template.events-view
  ]
}

这是 devops 定义：

projects = {
    devops = {
        ldap_cn = "activedirectory_group://CN=devops,OU=Distribution Groups,OU=My,DC=Company",
        name = "devops",
        # ...more attributes
    },
    # ...more projects
}

当我运行 terraform apply 我看到创建了角色和角色绑定：

rancher2_role_template.events-view: Creating...
rancher2_role_template.events-view: Creation complete after 0s [id=rt-h7xt4]
rancher2_cluster_role_template_binding.events-view: Creating...
rancher2_cluster_role_template_binding.events-view: Creation complete after 2s [id=c-6bdtb:events-view]

kubectl 显示集群角色和角色绑定（针对默认命名空间显示，但也在所有命名空间中复制）：

$ kubectl describe clusterrole rt-h7xt4
Name:         rt-h7xt4
Labels:       cattle.io/creator=norman

  ----   ----                                                                                         ---------
  Group  activedirectory_group://CN=devops,OU=Distribution Groups,OU=My,DC=Company

我的用户是 devops AD 组的成员，在 terraform apply 日志中我可以看到创建了角色和绑定模板，但是当我登录 Rancher 并单击Launch kubectl 我看不到任何命名空间的事件:

> kubectl get events 
Error from server (Forbidden): events is forbidden: User "u-w8rp43jtbn" cannot list resource "events" in API group "" in the namespace "default"
> kubectl get events -n devops
Error from server (Forbidden): events is forbidden: User "u-w8rp44jtbn" cannot list resource "events" in API group "" in the namespace "devops"

我试过在 api_groups 以及 Kubernetes 和 Rancher API 组中放置和空字符串，但似乎没有任何效果。

问题是我制作了集群角色模板而不是项目角色模板。在 rancher2_role_template 资源中，我添加了 context = "project" 并将 rancher2_cluster_role_template_binding 更改为 rancher2_project_role_template_binding.
