Resource Access Requests
With Teleport Resource Access Requests, users can request access to specific resources without needing to know anything about the roles or RBAC controls used under the hood. The Access Request API makes it easy to dynamically approve or deny these requests.
Just-in-time Access Requests are a feature of Teleport Enterprise. Teleport Community Edition users can get a preview of how Access Requests work by requesting a role via the Teleport CLI. Full Access Request functionality, including Resource Access Requests and an intuitive and searchable UI are available in Teleport Enterprise.
Prerequisites
-
A running Teleport cluster. If you want to get started with Teleport, sign up for a free trial.
-
The
tctl
admin tool andtsh
client tool.Visit Installation for instructions on downloading
tctl
andtsh
.
- To check that you can connect to your Teleport cluster, sign in with
tsh login
, then verify that you can runtctl
commands using your current credentials. For example:If you can connect to the cluster and run the$ tsh login --proxy=teleport.example.com [email protected]
$ tctl status
# Cluster teleport.example.com
# Version 17.0.0-dev
# CA pin sha256:abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678tctl status
command, you can use your current credentials to run subsequenttctl
commands from your workstation. If you host your own Teleport cluster, you can also runtctl
commands on the computer that hosts the Teleport Auth Service for full permissions.
Step 1/6. Grant roles to users
The built-in requester
and reviewer
roles have permissions to, respectively,
open and review Access Requests. Grant the requester
and reviewer
roles to
existing users, or create new users to test this feature. Make sure the
requester has a valid login
so that they can view and access SSH nodes.
$ tctl users add alice --roles requester --logins alice
$ tctl users add bob --roles reviewer
For the rest of the guide we will assume that the requester
role has been
granted to a user named alice
and the reviewer
role has been granted to a
user named bob
.
Consider defining custom roles to limit the scope of a requester or reviewer's permissions. Read the Access Request Configuration guide for available options.
Step 2/6. Search for resources
First, log in as alice
.
$ tsh login --proxy teleport.example.com --user alice
Notice that tsh ls
returns an empty list, because alice
does not have access to any resources by default.
$ tsh ls
Node Name Address Labels
--------- ------- ------
Then try searching for all available ssh nodes.
$ tsh request search --kind node

To request access to these resources, run
> tsh request create --resource /teleport.example.com/node/b1168402-9340-421a-a344-af66a6675738 --resource /teleport.example.com/node/bbb56211-7b54-4f9e-bee9-b68ea156be5f \
--reason <request reason>
You can search for resources of kind node
, kube_cluster
, db
, app
, and
windows_desktop
. Teleport also supports searching and requesting access to
resources within Kubernetes clusters.
List of supported Kubernetes resources
Teleport supports searching and requesting access to the following Kubernetes resources:
Requesting access to a Kubernetes namespace allows you to access all resources in that namespace, including the supported Kubernetes resources listed below. However, it prevents you from access any resources belonging to another namespace.
pod
secret
configmap
namespace
service
serviceaccount
kube_node
persistentvolume
persistentvolumeclaim
deployment
replicaset
statefulset
daemonset
clusterrole
kube_role
clusterrolebinding
rolebinding
cronjob
job

ingress
Advanced filters and queries are supported. See our filtering reference for more information.
Try narrowing your search to a specific resource you want to access.
$ tsh request search --kind node --search iot

Step 6/6. Resume regular access
While logged in with a Resource Access Request, users will be blocked from access to any other resources.
This is necessary because their certificate now contains an elevated role,
so it is restricted to only allow access to the resources they were specifically approved for.
Use the tsh request drop
command to "drop" the request and resume regular access.
$ tsh request drop
Next Steps
Automatically request access for SSH
Once you have configured Resource Access Requests,
tsh ssh
is able to automatically create a Resource Access Request for you when access is denied,
allowing you to skip the tsh request search
and tsh request create
steps.
$ tsh ssh alice@iot
ERROR: access denied to alice connecting to iot on cluster teleport.example.com
You do not currently have access to alice@iot, attempting to request access.

Restrict the resources a user can request access to
In this guide, we showed you how to enable a user to search for resources to
request access to. To do so, we assigned the user a Teleport role with the
search_as_roles
field set to the preset access
role.
You can impose further restrictions on the resources a user is allowed to
search by assigning search_as_roles
to a more limited role. Below, we will
show you which permissions you must set to restrict a user's ability to search
for different resources.
To restrict access to a particular resource using a role similar to the ones
below, edit one of the user's roles so the search_as_roles
field includes the
role you have created.
For full details on how to use Teleport roles to configure RBAC, see the Teleport Access Controls Reference.
node
You can restrict access to searching node
resources by assigning values to the
node_labels
field in the spec.allow
or spec.deny
fields. The following
role allows access to SSH Service instances with the env:staging
label.
kind: role
version: v5
metadata:
name: staging-access
spec:
allow:
node_labels:
env: staging
logins:
- "{{internal.logins}}"
options:
# Only allows the requester to use this role for 1 hour from time of request.
max_session_ttl: 1h
kube_cluster
You can restrict access to searching kube_cluster
resources by assigning
values to the kubernetes_labels
field in the spec.allow
or spec.deny
fields.
The following role allows access to Kubernetes clusters with the env:staging
label:
kind: role
metadata:
name: kube-access
version: v7
spec:
allow:
kubernetes_labels:
'env': 'staging'
kubernetes_resources:
- kind: '*'
namespace: '*'
name: '*'
deny: {}
Kubernetes resources
You can restrict access to Kubernetes resources by assigning values to the
kubernetes_resources
field in the spec.allow
or spec.deny
fields.
The following role allows access to Kubernetes pods with the name nginx
in any
namespace, and all pods in the dev
namespace:
kind: role
metadata:
name: kube-access
version: v7
spec:
allow:
kubernetes_labels:
'*':'*'
kubernetes_resources:
- kind: pod
namespace: "*"
name: "nginx*"
- kind: pod
namespace: "dev"
name: "*"
kubernetes_groups:
- viewers
deny: {}
Preventing unintended access to Kubernetes resources
If you are setting up a Teleport role to enable just-in-time access to a
specific Kubernetes resources, you should set the role's kubernetes_groups
and
kubernetes_users
to a role that has no access to Kubernetes resource beside
the Kubernetes resources that Teleport is able to restrict access for.
This is because, if a user requests access to a Kubernetes pod, and the request
is approved, the Teleport Kubernetes Service will use the kubernetes_groups
and kubernetes_users
fields in the role to add impersonation headers to the user's
requests to a Kubernetes API server. Under these conditions, Teleport will be able
to restrict access to all Kubernetes resources kinds mentioned above except for
the desired pod
. Teleport is also able to restrict access to namespaced-scoped
custom resources but not cluster-scoped custom resources - CRDs resources that
are cluster-scoped will be accessible to the user if the principals in the
kubernetes_users
and kubernetes_groups
fields have access to them.
Requesting access to a Kubernetes Namespace allows you to access all resources in that namespace but you won't be able to access any other supported resources in the cluster.
Restrict Access Requests to specific Kubernetes resource kinds
The request.kubernetes_resources
field allows you to restrict what kinds of Kubernetes
resources a user can request access to. Configuring this field to any value will disallow
requesting access to the entire Kubernetes cluster.
If the request.kubernetes_resources
field is not configured, then a user can request access
to any Kubernetes resources, including the entire Kubernetes cluster.
The following role allows users to request access to Kubernetes namespaces.
Requests for Kubernetes resources other than namespace
will not be allowed.
kind: role
metadata:
name: requester-kube-access
version: v7
spec:
allow:
request:
search_as_roles:
- "kube-access"
kubernetes_resources:
- kind: "namespace"
The following role allows users to request access only to Kubernetes namespaces and/or pods.
kind: role
metadata:
name: requester-kube-access
version: v7
spec:
allow:
request:
search_as_roles:
- "kube-access"
kubernetes_resources:
- kind: "namespace"
- kind: "pod"
The following role allows users to request access to any specific Kubernetes resources.
kind: role
metadata:
name: requester-kube-access
version: v7
spec:
allow:
request:
search_as_roles:
- "kube-access"
kubernetes_resources:
- kind: "*"
See related section about Kubernetes Resources
to see a list of supported kind
values.
The request.kubernetes_resources
field only restricts what kinds
of Kubernetes resource requests are allowed.
To control Kubernetes access to these resources see
Preventing unintended access to Kubernetes resources
section for more details.
db
You can restrict access to searching db
resources by assigning values to the
db_labels
field in the spec.allow
or spec.deny
fields.
The following role allows access to databases with the environment:dev
or
environment:stage
labels:
kind: role
version: v5
metadata:
name: developer
spec:
allow:
db_labels:
environment: ["dev", "stage"]
# Database account names this role can connect as.
db_users: ["viewer", "editor"]
db_names: ["*"]
app
You can restrict access to searching app
resources by assigning values to the
app_labels
field in the spec.allow
or spec.deny
fields.
The following role allows access to all applications except for those in
env:prod
:
kind: role
version: v5
metadata:
name: dev
spec:
allow:
app_labels:
"*": "*"
deny:
app_labels:
env: "prod"
windows_desktop
You can restrict access to searching windows_desktop
resources by assigning
values to the windows_desktop_labels
field in the spec.allow
or spec.deny
fields.
The following role allows access to all Windows desktops with the
environment:dev
or environment:stage
labels.
kind: role
version: v4
metadata:
name: developer
spec:
allow:
windows_desktop_labels:
environment: ["dev", "stage"]
windows_desktop_logins: ["{{internal.windows_logins}}"]
Request access to Kubernetes resources
Teleport users can request access to a Kubernetes resources by running the following command:
$ tsh request create resource-id
Namespace-scoped resources
For Kubernetes namespaced resources, the resource-id
is in the following format:
/TELEPORT_CLUSTER/NAMESPACED_KIND/KUBE_CLUSTER/NAMESPACE/RESOURCE_NAME
Teleport supports the following namespaced resources: pod
, secret
, configmap
,
service
, serviceaccount
, persistentvolumeclaim
, deployment
, replicaset
,
statefulset
, daemonset
, kube_role
, rolebinding
, cronjob
, job
,
ingress
.
For example, to request access to a pod called nginx-1
in the development
namespace, run the following command:
$ tsh request create --resources /teleport.example.com/pod/mycluster/development/nginx-1
For the NAMESPACE
and RESOURCE_NAME
values, you can match ranges of characters by
supplying a wildcard (*
) or regular expression. Regular expressions must begin
with ^
and end with $
.
For example, to create a request to access all pods in all namespaces that match
the regular expression /^nginx-[a-z0-9-]+$/
, run the following command:
$ tsh request create --resources /teleport.example.com/pod/mycluster/*/^nginx-[a-z0-9-]+$
Cluster-scoped resources
For Kubernetes cluster-scoped resources, the resource-id
is in the following format:
/TELEPORT_CLUSTER/CLUSTER_WIDE_KIND/KUBE_CLUSTER/RESOURCE_NAME
Teleport supports the following cluster-wide resources: namespace
, kube_node
,
clusterrole
, clusterrolebinding
, persistentvolume
, certificatesigningrequest
.
For example, to request access to a namespace called prod
, run the following command:
$ tsh request create --resources /teleport.example.com/namespace/mycluster/prod
For the RESOURCE_NAME
value, you can match ranges of characters by
supplying a wildcard (*
) or regular expression. Regular expressions must begin
with ^
and end with $
.
For example, to create a request to access all namespaces prefixed with dev
match
the regular expression /^dev-[a-z0-9-]+$/
, run the following command:
$ tsh request create --resources /teleport.example.com/namespace/mycluster/^dev-[a-z0-9-]+$
Using cluster-scoped resource requests requires the role under search_as_roles
to have the correct
permissions for the cluster-scoped resource. This is an example of the required permissions to
request access only to the namespace prod
(and all resources within it):
kind: role
spec:
allow:
kubernetes_resources:
- kind: namespace
name: prod
verbs:
- '*'
Search for Kubernetes resources
If a user has no access to a Kubernetes cluster, they can search the list of resources in the cluster by running the following command:
$ tsh request search --kind=<kind> --kube-cluster=kube-cluster \
[--kube-namespace=namespace|--all-kube-namespaces]
Name Namespace Labels Resource ID
----------------- --------- --------- ----------------------------------------------------------
nginx-deployment-0 default app=nginx /teleport.example.com/pod/local/default/nginx-deployment-0
nginx-deployment-1 default app=nginx /teleport.example.com/pod/local/default/nginx-deployment-1
To request access to these resources, run
> tsh request create --resource /teleport.example.com/pod/local/default/nginx-deployment-0 --resource /teleport.example.com/pod/local/default/nginx-deployment-1 \
--reason <request reason>
The list returned includes the name of the resource, the namespace it is in if
applicable, its labels, and the resource ID.
Resources included in the list are those that match the kubernetes_resources
field in the user's search_as_roles
. The user can then:
- Request access to the resources by running the command provided by the
tsh request search
command. - Edit the command to request access to a subset of the resources.
- Use a custom request with wildcards or regular expressions.
tsh request search --kind=<kind>
works even if the user has no permissions to interact
with the desired Kubernetes cluster, but the user's search_as_roles
values
must allow access to the cluster. If the user is unsure of the name of the cluster,
they can run the following command to search it:
$ tsh request search --kind=kube_cluster
Name Hostname Labels Resource ID
