Cannot list namespaces at the cluster scope

GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Node: User "system:serviceaccount:kube-system:heapster" cannot list nodes at the cluster scope.

Pod: User "system:serviceaccount:kube-system:heapster" cannot list pods at the cluster scope. Make sure that role is present if not, sync your bootstrap policyand make sure there's a clusterrolebinding binding the kube-system:heapster serviceaccount to that clusterrole.

Just bumped into it as well and solved it by doing [1]. Maybe the step is just missing in the guide? Skip to content. This repository has been archived by the owner.

Currently, it is required to give user permission to list namespaces as it is not possible to manually provide a namespace.

I'm a bit confused here. Cannot get access neither if I type in the namespace manually. Would love it to work just like how the K8s API access via kubectl works: My team is only allowed API interactions against it's namespace, nothing more. Right now, unless I'm missing something, the permissions the dashboard requires leaves us at a strange place in-between unfortunately.

For read access you do not need to grant namespace list privileges. Namespace selector has input field that allows you to write the name of namespace you want to access. Without list privilege namespace selector list will be empty but input field will always be available. This issue only mentions that you can not use create functionality without this permission. Other parts of Dashboard are working correctly. I been using it in minikube and love it.

In v2 you can specify namespace on your own without list permission. Sign up for free to join this conversation on GitHub.

Even after granting cluster roles to user, I get Error from server Forbidden : User "system:anonymous" cannot list nodes at the cluster scope. Your problem is not with your ClusterRoleBindings but rather with user authentication. In your specific case the reason for that is that the username flag uses HTTP Basic authentication and needs the password flag to actually do anything.

But even if you did supply the password, you'd still need to actually tell the API server to accept that specific user.

Have a look at this part of the Kubernetes documentation which deals with different methods of authentication. For the username and password authentication to work, you'd want to look at the Static Password File section, but I would actually recommend you go with X Client Certs since they are more secure and are operationally much simpler no secrets on the Server, no state to replicate between API servers.

But in my case i am using OIDC. Please correct me if I am wrong. In that case you need to drop the username option from kubectl and correctly configure your OIDC credentials in kubectl.

I guess the user needs to use the certificate and key to talk to the apiserver. I will have to use the user's email ID to access the api server.

RBAC authorization uses the rbac. You can describe objectsor amend them, using tools such as kubectl, just like any other Kubernetes object. A Role always sets permissions within a particular namespace An abstraction used by Kubernetes to support multiple virtual clusters on the same physical cluster. ClusterRole, by contrast, is a non-namespaced resource. If you want to define a role within a namespace, use a Role; if you want to define a role cluster-wide, use a ClusterRole. A Pod represents a set of running containers on your cluster.

A ClusterRole can be used to grant the same permissions as a Role. Because ClusterRoles are cluster-scoped, you can also use them to grant access to:. Here is an example of a ClusterRole that can be used to grant read access to secrets Stores sensitive information, such as passwords, OAuth tokens, and ssh keys.

The name of a Role or a ClusterRole object must be a valid path segment name. A role binding grants the permissions defined in a role to a user or set of users. It holds a list of subjects users, groups, or service accountsand a reference to the role being granted. A RoleBinding grants permissions within a specific namespace whereas a ClusterRoleBinding grants that access cluster-wide. A RoleBinding may reference any Role in the same namespace.

If you want to bind a ClusterRole to all the namespaces in your cluster, you use a ClusterRoleBinding. This kind of reference lets you define a set of common roles across your cluster, then reuse them within multiple namespaces.

To grant permissions across a whole cluster, you can use a ClusterRoleBinding. After you create a binding, you cannot change the Role or ClusterRole that it refers to.

If you do want to change the roleRef for a binding, you need to remove the binding object and create a replacement. The kubectl auth reconcile command-line utility creates or updates a manifest file containing RBAC objects, and handles deleting and recreating binding objects if required to change the role they refer to. See command usage and examples for more information. In the Kubernetes API, most resources are represented and accessed using a string representation of their object name, such as pods for a Pod.

In this case, pods is the namespaced resource for Pod resources, and log is a subresource of pods. To allow a subject to read pods and also access the log subresource for each of those Pods, you write:. You can also refer to resources by name for certain requests through the resourceNames list. When specified, requests can be restricted to individual instances of a resource. Here is an example that restricts its subject to only get or update a ConfigMap An API object used to store non-confidential data in key-value pairs.

Can be consumed as environment variables, command-line arguments, or config files in a volume. You can aggregate several ClusterRoles into one combined ClusterRole. A controller, running as part of the cluster control plane, watches for ClusterRole objects with an aggregationRule set.

The aggregationRule defines a label selector Allows users to filter a list of resources based on labels. If you create a new ClusterRole that matches the label selector of an existing aggregated ClusterRole, that change triggers adding the new rules into the aggregated ClusterRole.

The default user-facing roles use ClusterRole aggregation. This lets you, as a cluster administrator, include rules for custom resources, such as those served by CustomResourceDefinitions Custom code that defines a resource to add to your Kubernetes API server without building a complete custom server. The following examples are excerpts from Role or ClusterRole objects, showing only the rules section. Allow reading the resource "nodes" in the core group because a Node is cluster-scoped, this must be in a ClusterRole bound with a ClusterRoleBinding to be effective :.

I couldn't find any information about different types of scope.

If I cannot create namespace at the cluster scope, where can I create the namespace? How can I check which "scopes" do I have access to? This answer suggest in a Google Cloud environment :. Issues such as this may be more likely if you are using an older version of gcloud on your home workstation or elsewhere. Is this GKE? If so RBAC is enabled by default - you may need to grant yourself cluster-admin role to create namespaces. Resources within kubernetes are either namespaced exist within a containing namespace or cluster scoped are not contained within a namespace.

Examples of namespaced resources are pods, configmaps, and serviceaccounts. Examples of cluster scoped resources are nodes, persistentvolumes, and namespaces themselves. When an operation is forbidden, the message indicates which scope the operation was forbidden at, and if the resource is namespaced, which namespace the operation was attempted within.
