With dynamic Kubernetes cluster registration, you can manage the Kubernetes clusters connected to your Teleport cluster without needing to modify the configuration file of an individual Kubernetes Service instance.
Dynamic Kubernetes cluster registration is useful when you have deployed multiple Kubernetes Service instances or need to regularly reconfigure access to Kubernetes clusters in your infrastructure.
In this guide, we will show you how to set up dynamic Kubernetes cluster
registration, then create, list, update, and delete Kubernetes clusters via
tctl
.
Prerequisites
-
A running Teleport cluster. For details on how to set this up, see one of our Getting Started guides.
-
The
tctl
admin tool andtsh
client tool version >= 12.1.1.tctl versionTeleport v12.1.1 go1.19
tsh versionTeleport v12.1.1 go1.19
See Installation for details.
-
A running Teleport Enterprise cluster. For details on how to set this up, see our Enterprise Getting Started guide.
-
The Enterprise
tctl
admin tool andtsh
client tool version >= 12.1.1, which you can download by visiting the customer portal.tctl versionTeleport Enterprise v12.1.1 go1.19
tsh versionTeleport v12.1.1 go1.19
Please use the latest version of Teleport Enterprise documentation.
-
A Linux host where you will install the Teleport Kubernetes Service.
Our
teleport-kube-agent
Helm chart does not support dynamic Kubernetes cluster registration. -
A Kubernetes cluster to join to your Teleport cluster. You must have permissions to create namespaces, secrets, service accounts, cluster roles, and cluster role bindings in the cluster.
To connect to Teleport, log in to your cluster using tsh
, then use tctl
remotely:
tsh login --proxy=teleport.example.com [email protected]tctl statusCluster teleport.example.com
Version 12.1.1
CA pin sha256:abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678
You can run subsequent tctl
commands in this guide on your local machine.
For full privileges, you can also run tctl
commands on your Auth Service host.
To connect to Teleport, log in to your cluster using tsh
, then use tctl
remotely:
tsh login --proxy=myinstance.teleport.sh [email protected]tctl statusCluster myinstance.teleport.sh
Version 12.1.2
CA pin sha256:sha-hash-here
You must run subsequent tctl
commands in this guide on your local machine.
Step 1/3. Set up the Teleport Kubernetes Service
The Teleport Kubernetes Service proxies traffic from Teleport users to a Kubernetes API server so you can take advantage of passwordless authentication, role-based access controls, audit logging, and other Teleport features in order to manage access to Kubernetes.
In this step, you will install the Teleport Kubernetes Service on a Linux host and configure it to access any Kubernetes cluster you register with your Teleport cluster.
Get a join token
Establish trust between your Teleport cluster and your new Kubernetes Service instance by creating a join token:
tctl nodes add --roles=kubeThe invite token: abcd123-insecure-do-not-use-this
This token will expire in 30 minutes.
Run this on the new node to join the cluster:
> teleport start \
--roles=kube \
--token=abcd123-insecure-do-not-use-this \
--ca-pin=sha256:abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678 \
--auth-server=192.0.2.255:3025
Please note:
- This invitation token will expire in 30 minutes
- 192.0.2.255:3025 must be reachable from the new node
Copy the token and keep it somewhere safe so you can use it when running the Teleport Kubernetes Service.
Install the Teleport Kubernetes Service
Install the Teleport Kubernetes Service on your Linux host:
Use the appropriate commands for your environment to install your package.
Teleport Edition
Add the Teleport repository to your repository list:

Please use the latest version of Teleport Enterprise documentation.
Configure the Teleport Kubernetes Service
On the host where you will run the Teleport Kubernetes Service, run the
following command to create a base configuration for your Teleport instance,
assigning PROXY_SERVICE
to the host and port of your Teleport Proxy Service or
Teleport Cloud tenant and TOKEN
to the join token we created earlier:
e.g., teleport.example.com:443
PROXY_SERVICE=proxy-addre.g., abcd123-insecure-do-not-use-this;
TOKEN=join-token;sudo teleport configure \--proxy=${PROXY_SERVICE?} \--roles=kube \--token=${TOKEN?} \-o file
Edit your configuration file at /etc/teleport.yaml
to include the following:
kubernetes_service:
enabled: "yes"
resources:
- labels:
"*": "*"
This configuration enables your Kubernetes Service instance to connect to any
Kubernetes clusters you register with your Teleport cluster. This is because the
resources[0].labels
field includes the wildcard pattern ("*": "*"
), which
allows this Kubernetes Service instance to connect to Kubernetes cluster
resources with any label key or value.
You can configure a Kubernetes Service instance to watch for a subset of Kubernetes clusters by including specific label keys and values instead of wildcard characters:
resources:
- labels:
"env": "prod"
"region": "us-east-2"
- labels:
"env": "test"
"region": "us-west-1"
For the Kubernetes Service to register a cluster, any of the items in
resources
must match the cluster's labels. For an item in resources
to
match, all of the labels
entries within that item must match the cluster's
labels.
For example, a cluster with the labels env:prod
and region:us-west-1
would
not match the configuration above, since it only matches the env:prod
label in
the first resources
item and the region:us-west-1
label in the second
resources
item.
However, a cluster with env:test
and region:us-west-1
would match, since it
matches both labels given in the second resources
item.
When you create dynamic Kubernetes cluster resources later in this guide, you can assign them labels to ensure that only specific Kubernetes Service instances will watch for them.
Run the Teleport Kubernetes Service
On the host where you will run the Teleport Kubernetes Service, execute the following command, depending on whether you installed Teleport using a package manager or via a TAR archive:
sudo systemctl start teleport
sudo teleport install systemd --output=/etc/systemd/system/teleport.service;sudo systemctl enable teleport;sudo systemctl start teleport;
Step 2/3. Authorize your user
To enable dynamic Kubernetes cluster registration in Teleport, you will need to authorize your user to access the Kubernetes clusters you want to register with Teleport. We will configure this access in this step, both in Teleport and on your Kubernetes cluster.
Allow access to your Kubernetes cluster
Ensure that you are in the correct Kubernetes context for the cluster you would like to enable access to.
Retrieve all available contexts:
kubectl config get-contexts
Switch to your context, replacing CONTEXT_NAME
with the name of your chosen
context:
kubectl config use-context CONTEXT_NAMESwitched to context CONTEXT_NAME
Kubernetes authentication
To authenticate to a Kubernetes cluster via Teleport, your Teleport roles must allow access as at least one Kubernetes user or group. Ensure that you have a Teleport role that grants access to the cluster you plan to interact with.
Run the following command to get the Kubernetes user for your current context:
kubectl config view \-o jsonpath="{.contexts[?(@.name==\"$(kubectl config current-context)\")].context.user}"
Create a file called kube-access.yaml
with the following content, replacing
USER
with the output of the command above.
kind: role
metadata:
name: kube-access
version: v6
spec:
allow:
kubernetes_labels:
'*': '*'
kubernetes_resources:
- kind: pod
namespace: "*"
name: "*"
kubernetes_groups:
- viewers
kubernetes_users:
- USER
deny: {}
Apply your changes:
tctl create -f kube-access.yaml
Assign the kube-access
role to your Teleport user by running the following
commands, depending on whether you authenticate as a local Teleport user or via
the github
, saml
, or oidc
authentication connectors:
Retrieve your local user's configuration resource:
tctl get users/$(tsh status -f json | jq -r '.active.username') > out.yaml
Edit out.yaml
, adding kube-access
to the list of existing roles:
roles:
- access
- auditor
- editor
+ - kube-access
Apply your changes:
tctl create -f out.yaml
Retrieve your github
configuration resource:
tctl get github/github --with-secrets > github.yaml
Edit github.yaml
, adding kube-access
to the
teams_to_roles
section. The team you will map to this role will depend on how
you have designed your organization's RBAC, but it should be the smallest team
possible within your organization. This team must also include your user.
Here is an example:
teams_to_roles:
- organization: octocats
team: admins
roles:
- access
+ - kube-access
Apply your changes:
tctl create -f github.yaml
Note the --with-secrets
flag in the tctl get
command. This adds the value of
spec.signing_key_pair.private_key
to saml.yaml
. This is a sensitive value,
so take precautions when creating this file and remove it after updating the resource.
Retrieve your saml
configuration resource:
tctl get --with-secrets saml/mysaml > saml.yaml
Edit saml.yaml
, adding kube-access
to the
attributes_to_roles
section. The attribute you will map to this role will
depend on how you have designed your organization's RBAC, but it should be the
smallest group possible within your organization. This group must also include
your user.
Here is an example:
attributes_to_roles:
- name: "groups"
value: "my-group"
roles:
- access
+ - kube-access
Apply your changes:
tctl create -f saml.yaml
Note the --with-secrets
flag in the tctl get
command. This adds the value of
spec.signing_key_pair.private_key
to saml.yaml
. This is a sensitive value,
so take precautions when creating this file and remove it after updating the resource.
Retrieve your oidc
configuration resource:
tctl get oidc/myoidc --with-secrets > oidc.yaml
Edit oidc.yaml
, adding kube-access
to the
claims_to_roles
section. The claim you will map to this role will depend on
how you have designed your organization's RBAC, but it should be the smallest
group possible within your organization. This group must also include your
user.
Here is an example:
claims_to_roles:
- name: "groups"
value: "my-group"
roles:
- access
+ - kube-access
Apply your changes:
tctl create -f saml.yaml
Note the --with-secrets
flag in the tctl get
command. This adds the value of
spec.signing_key_pair.private_key
to saml.yaml
. This is a sensitive value,
so take precautions when creating this file and remove it after updating the resource.
Log out of your Teleport cluster and log in again to assume the new role.
Now that Teleport RBAC is configured, you can authenticate to your Kubernetes cluster via Teleport. To interact with your Kubernetes cluster, you will need to configure authorization within Kubernetes.
Kubernetes authorization
To configure authorization within your Kubernetes cluster, you need to create Kubernetes RoleBinding
s or
ClusterRoleBindings
that grant permissions to the subjects listed in kubernetes_users
and
kubernetes_groups
.
For example, you can grant some limited read-only permissions to the viewers
group used in the kube-access
role defined above:
Create a file called viewers-bind.yaml
with the following contents:
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: viewers-crb
subjects:
- kind: Group
# Bind the group "viewers", corresponding to the kubernetes_groups we assigned our "kube-access" role above
name: viewers
apiGroup: rbac.authorization.k8s.io
roleRef:
kind: ClusterRole
# "view" is a default ClusterRole that grants read-only access to resources
# See: https://kubernetes.io/docs/reference/access-authn-authz/rbac/#user-facing-roles
name: view
apiGroup: rbac.authorization.k8s.io
Apply the ClusterRoleBinding
with kubectl
:
kubectl apply -f viewers-bind.yaml
Log out of Teleport and log in again.
Authorize your user to manage Kubernetes clusters
Teleport tracks Kubernetes clusters in your infrastructure via dynamic
kube_cluster
resources. To manage access to Kubernetes clusters with Teleport,
your user will need permissions to manage these resources.
In the previous section, you authorized your user to access all Kubernetes clusters registered in your Teleport cluster. Now that you can access these clusters, create a role that enables you to manage them.
Create a role definition called kube-manager.yaml
with the following content:
kind: role
metadata:
name: kube-manager
spec:
allow:
rules:
- resources:
- kube_cluster
verbs:
- list
- create
- read
- update
- delete
version: v5
Create the role:
tctl create -f kube-manager.yaml
Assign the kube-manager
role to your Teleport user by running the following
commands, depending on whether you authenticate as a local Teleport user or via
the github
, saml
, or oidc
authentication connectors:
Retrieve your local user's configuration resource:
tctl get users/$(tsh status -f json | jq -r '.active.username') > out.yaml
Edit out.yaml
, adding kube-manager
to the list of existing roles:
roles:
- access
- auditor
- editor
+ - kube-manager
Apply your changes:
tctl create -f out.yaml
Retrieve your github
configuration resource:
tctl get github/github --with-secrets > github.yaml
Edit github.yaml
, adding kube-manager
to the
teams_to_roles
section. The team you will map to this role will depend on how
you have designed your organization's RBAC, but it should be the smallest team
possible within your organization. This team must also include your user.
Here is an example:
teams_to_roles:
- organization: octocats
team: admins
roles:
- access
+ - kube-manager
Apply your changes:
tctl create -f github.yaml
Note the --with-secrets
flag in the tctl get
command. This adds the value of
spec.signing_key_pair.private_key
to saml.yaml
. This is a sensitive value,
so take precautions when creating this file and remove it after updating the resource.
Retrieve your saml
configuration resource:
tctl get --with-secrets saml/mysaml > saml.yaml
Edit saml.yaml
, adding kube-manager
to the
attributes_to_roles
section. The attribute you will map to this role will
depend on how you have designed your organization's RBAC, but it should be the
smallest group possible within your organization. This group must also include
your user.
Here is an example:
attributes_to_roles:
- name: "groups"
value: "my-group"
roles:
- access
+ - kube-manager
Apply your changes:
tctl create -f saml.yaml
Note the --with-secrets
flag in the tctl get
command. This adds the value of
spec.signing_key_pair.private_key
to saml.yaml
. This is a sensitive value,
so take precautions when creating this file and remove it after updating the resource.
Retrieve your oidc
configuration resource:
tctl get oidc/myoidc --with-secrets > oidc.yaml
Edit oidc.yaml
, adding kube-manager
to the
claims_to_roles
section. The claim you will map to this role will depend on
how you have designed your organization's RBAC, but it should be the smallest
group possible within your organization. This group must also include your
user.
Here is an example:
claims_to_roles:
- name: "groups"
value: "my-group"
roles:
- access
+ - kube-manager
Apply your changes:
tctl create -f saml.yaml
Note the --with-secrets
flag in the tctl get
command. This adds the value of
spec.signing_key_pair.private_key
to saml.yaml
. This is a sensitive value,
so take precautions when creating this file and remove it after updating the resource.
Log out of your Teleport cluster and log in again to assume the new role.
Step 3/3. Manage dynamic Kubernetes cluster resources
Now that your Teleport user has permissions to manage Kubernetes cluster resources, we will show you how to create, list, update, and delete them.
Create a kubeconfig
In this section, you will create a Kubernetes Config
resource, or kubeconfig,
that your Teleport cluster will use to authenticate to your Kubernetes cluster.
When you signed into Teleport earlier in this guide, tsh
may have changed your
Kubernetes context to one based on your Teleport cluster, so make sure you
update your Kubernetes context to match the cluster you would like to connect to
Teleport:
kubectl config get-contextsAssign CONTEXT_NAME to your chosen context
kubectl config use-context CONTEXT_NAME
On your workstation, download Teleport's get-kubeconfig.sh
script, which you
will use to generate the kubeconfig:
curl -OL \https://raw.githubusercontent.com/gravitational/teleport/v12.1.1/examples/k8s-auth/get-kubeconfig.sh
The script creates a service account for the Teleport Kubernetes Service that
can get Kubernetes pods as well as impersonate users, groups, and other service
accounts. The Teleport Kubernetes Service uses this service account to manage
access to resources in your Kubernetes cluster. The script also ensures that
there is a Kubernetes Secret
in your cluster to store service account
credentials.
get-kubeconfig.sh
creates a namespace called teleport
for the resources it
deploys, though you can choose a different name by assigning the
TELEPORT_NAMESPACE
environment variable in the shell where you run the script.
After creating resources, get-kubeconfig.sh
writes a new kubeconfig to a file
called kubeconfig
in the directory where you run the script.
Run the get-kubeconfig.sh
script:
bash get-kubeconfig.sh
The script is successful if you see this message:
Done!
Ignore the script's instructions to copy the generated kubeconfig file to the
Teleport Proxy Service. In the next section, we will show you how to use the
kubeconfig file when creating a dynamic kube_cluster
resource.
Create a Kubernetes cluster resource
Define a kube_cluster
resource with the following content in a file called
kube_cluster.yaml
:
kind: kube_cluster
version: v3
metadata:
name: mycluster
spec:
kubeconfig: |
The spec.kubeconfig
field in the snippet above begins a multi-line string.
Below, you will include the contents of the kubeconfig file as its value.
Since spec.kubeconfig
must be a base64-encoded string, convert the kubeconfig
file to base64, then indent it and add it to the kube_cluster.yaml
resource
definition using the following command:
printf " %s" $(cat kubeconfig | base64) >> kube_cluster.yaml
You can add labels to the kube_cluster
resource, allowing you to manage access
to specific clusters from your Teleport roles or Kubernetes Service instances.
Labels can either be static or dynamic. Static labels are key/value pairs. This
example defines the env=prod
and team=dev
labels:
kind: kube_cluster
version: v3
metadata:
name: mycluster
labels:
env: prod
team: dev
spec:
kubeconfig: KUBECONFIG
You can also add dynamic labels, which define shell commands that a Kubernetes
Service instance will execute in order to generate labels. To do so, edit the
spec.dynamic_labels
field of a kube_cluster
resource.
This example runs the python3 get_region.py
command to fetch the region in
which the Kubernetes Service is deployed and assign the result to the region
key:
kind: kube_cluster
version: v3
metadata:
name: mycluster
spec:
kubeconfig: KUBECONFIG
dynamic_labels:
region:
period: "24h"
command: ["python3", "get_region.py"]
When defining a dynamic label, the key within the spec.dynamic_labels
field
behaves the same as keys within the metadata.labels
field, indicating the key
of the label.
The Kubernetes Service obtains a value for that key by running the
command given in command
every period
. command
is an array of strings,
where the first element indicates the command to execute and each subsequent
element indicates an argument.
period
is a Go duration string, which includes a number and a unit of time.
Supported units are ns
, us
(or µs
), ms
, s
, m
, and h
. The example
above configures the Kubernetes Service to run the command every day.
To create the kube_cluster
resource, run the following command:
tctl create kube_cluster.yamlkubernetes cluster "mycluster" has been created
Access your new Kubernetes cluster
Instances of the Teleport Kubernetes Service watch for newly created or updated
kube_cluster
resources. When you create the kube_cluster
resource, any
Kubernetes Service instances you have configured to track that cluster's labels
will register that cluster and enable access to it via Teleport.
As a result, you should now see the cluster you registered above when you run
tsh kube ls
:
tsh kube lsKube Cluster Name Labels Selected
----------------- --------------------------- --------
mycluster teleport.dev/origin=dynamic
The teleport.dev/origin=dynamic
label indicates that the cluster was
registered dynamically.
You can also log in to the cluster you just registered:
tsh kube login myclusterLogged into kubernetes cluster "mycluster". Try 'kubectl version' to test the
connection.
List Kubernetes cluster resources
You can list kube_cluster
resources with the following command:
tctl get kube_clusters
Update a Kubernetes cluster resource
To update the kube_cluster
resource you created earlier, execute the following
command to retrieve the resource as it exists on the Auth Service's backend:
tctl get kube_clusters/mycluster > kube_cluster.yaml
Edit the kube_cluster.yaml
file to add a label to your kube_cluster
:
kind: kube_cluster
metadata:
id: 9999999999999999999
labels:
teleport.dev/origin: dynamic
+ env: test
name: mycluster
spec:
aws: {}
azure: {}
kubeconfig: KUBECONFIG
version: v3
Update the resource:
tctl create -f kube_cluster.yamlkubernetes cluster "mycluster" has been updated
You should now see the updated labels:
tsh kube lsKube Cluster Name Labels Selected
----------------- ------------------------------------ --------
mycluster env=test teleport.dev/origin=dynamic *
If the updated kube_cluster
resource's labels no longer match the ones a Teleport
Kubernetes Service instance is configured to watch, the instance will unregister
and stop proxying the Kubernetes cluster.
Delete Kubernetes cluster resources
To delete the kube_cluster
resource you created earlier, run the following
command:
tctl rm kube_clusters/myclusterkubernetes cluster "mycluster" has been deleted
This will unregister the Kubernetes cluster from Teleport:
tsh kube lsKube Cluster Name Labels Selected
----------------- ------ --------
