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，我似乎无法向我的群组devops授予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的定义：

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

运行terraform apply时，我看到角色和角色绑定已创建：

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（显示默认名称空间，但在所有名称空间中也重复）：

$ kubectl describe clusterrole rt-h7xt4
Name:         rt-h7xt4

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

我的用户是devops AD组的成员，并且在terraform apply日志中，我看到角色和绑定模板已创建，但是当我登录Rancher并单击{{ 1}}我看不到任何名称空间的事件：

Launch kubectl

我曾尝试在> 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"以及Kubernetes和Rancher API组中放入空字符串，但是似乎没有任何作用。

问题是我制作了群集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。

授予事件查看Terraform的权限
