Teleport can provide secure access to PostgreSQL via the Teleport Database Service. This allows for fine-grained access control through Teleport's RBAC.
In this guide, you will:
- Configure an PostgreSQL database with mutual TLS authentication.
- Join the PostgreSQL database to your Teleport cluster.
- Connect to the PostgreSQL database via the Teleport Database Service.

- A self-hosted PostgreSQL instance.
- Command-line client
psql
installed and added to your system'sPATH
environment variable. - A host, e.g., an Amazon EC2 instance, where you will run the Teleport Database Service.
- 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.tctl
is supported on macOS and Linux machines. For example:If you can connect to the cluster and run thetsh login --proxy=teleport.example.com --user=[email protected]tctl statusCluster teleport.example.com
Version 14.2.1
CA pin sha256:abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678
tctl 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 1/5. Create a Teleport token and user
The Database Service requires a valid auth token to connect to the cluster. Generate
one by running the following command against your Teleport Auth Service and save
it in /tmp/token
on the node that will run the Database Service:
tctl tokens add --type=db
Create a Teleport user
To modify an existing user to provide access to the Database Service, see Database Access Access Controls
Create a local Teleport user with the built-in access
role:
tctl users add \ --roles=access \ --db-users=\* \ --db-names=\* \ alice
Create a local Teleport user with the built-in access
and requester
roles:
tctl users add \ --roles=access,requester \ --db-users=\* \ --db-names=\* \ alice
Flag | Description |
---|---|
--roles | List of roles to assign to the user. The builtin access role allows them to connect to any database server registered with Teleport. |
--db-users | List of database usernames the user will be allowed to use when connecting to the databases. A wildcard allows any user. |
--db-names | List of logical databases (aka schemas) the user will be allowed to connect to within a database server. A wildcard allows any database. |
Database names are only enforced for PostgreSQL and MongoDB databases.
For more detailed information about database access controls and how to restrict access see RBAC documentation.
Step 2/5. Create a certificate/key pair
Teleport uses mutual TLS authentication with self-hosted databases. These databases must be configured with Teleport's certificate authority to be able to verify client certificates. They also need a certificate/key pair that Teleport can verify.
If you are using Teleport Cloud, your Teleport user must be allowed to
impersonate the system role Db
in order to be able to generate the database
certificate.
Include the following allow
rule in in your Teleport Cloud user's role:
allow:
impersonate:
users: ["Db"]
roles: ["Db"]
Create the secrets:
Export Teleport's certificate authority and a generate certificate/key pair
for host db.example.com with a 1-year validity period.
tctl auth sign --format=db --host=db.example.com --out=server --ttl=2190h
In this example, db.example.com
is the hostname where the Teleport Database
Service can reach the PostgreSQL server.
We recommend using a shorter TTL, but keep mind that you'll need to update the database server certificate before it expires to not lose the ability to connect. Pick the TTL value that best fits your use-case.
The command will create 3 files: server.cas
, server.crt
and server.key
which you'll need to enable mutual TLS on your PostgreSQL server.
Step 3/5. Configure your PostgreSQL server
To configure your PostgreSQL server to accept TLS connections, add the following
to the PostgreSQL configuration file, postgresql.conf
:
ssl = on
ssl_cert_file = '/path/to/server.crt'
ssl_key_file = '/path/to/server.key'
ssl_ca_file = '/path/to/server.cas'
See Secure TCP/IP Connections with SSL in the PostgreSQL documentation for more details.
Additionally, PostgreSQL should be configured to require client certificate
authentication from clients connecting over TLS. This can be done by adding
the following entries to PostgreSQL's host-based authentication file pg_hba.conf
:
hostssl all all ::/0 cert
hostssl all all 0.0.0.0/0 cert
You should also ensure that you have no higher-priority md5
authentication
rules that will match, otherwise PostgreSQL will offer them first, and the
certificate-based Teleport login will fail.
See The pg_hba.conf File in the PostgreSQL documentation for more details.
Step 4/5. Configure and Start the Database Service
Install and configure Teleport where you will run the Teleport Database Service:
Select an edition, then follow the instructions for that edition to install Teleport.

OS repository channels
The following channels are available for APT, YUM, and Zypper repos. They may be used in place of
stable/v14
anywhere in the Teleport documentation.
Channel name | Description |
---|---|
stable/<major> | Receives releases for the specified major release line, i.e. v14 |
stable/cloud | Rolling channel that receives releases compatible with current Cloud version |
stable/rolling | Rolling channel that receives all published Teleport releases |
Before installing a teleport
binary with a version besides
v14, read our compatibility rules to ensure that the
binary is compatible with Teleport Cloud.
When running multiple teleport
binaries within a cluster, the following rules
apply:
- Patch and minor versions are always compatible, for example, any 8.0.1 component will work with any 8.0.3 component and any 8.1.0 component will work with any 8.3.0 component.
- Servers support clients that are 1 major version behind, but do not support
clients that are on a newer major version. For example, an 8.x.x Proxy Service
is compatible with 7.x.x resource services and 7.x.x
tsh
, but we don't guarantee that a 9.x.x resource service will work with an 8.x.x Proxy Service. This also means you must not attempt to upgrade from 6.x.x straight to 8.x.x. You must upgrade to 7.x.x first. - Proxy Services and resource services do not support Auth Services that are on
an older major version, and will fail to connect to older Auth Services by
default. This behavior can be overridden by passing
--skip-version-check
when starting Proxy Services and resource services.

Before installing a teleport
binary with a version besides v14,
read our compatibility rules to ensure that the binary is compatible with
Teleport Enterprise Cloud.
When running multiple teleport
binaries within a cluster, the following rules
apply:
- Patch and minor versions are always compatible, for example, any 8.0.1 component will work with any 8.0.3 component and any 8.1.0 component will work with any 8.3.0 component.
- Servers support clients that are 1 major version behind, but do not support
clients that are on a newer major version. For example, an 8.x.x Proxy Service
is compatible with 7.x.x resource services and 7.x.x
tsh
, but we don't guarantee that a 9.x.x resource service will work with an 8.x.x Proxy Service. This also means you must not attempt to upgrade from 6.x.x straight to 8.x.x. You must upgrade to 7.x.x first. - Proxy Services and resource services do not support Auth Services that are on
an older major version, and will fail to connect to older Auth Services by
default. This behavior can be overridden by passing
--skip-version-check
when starting Proxy Services and resource services.
On the host where you will run the Teleport Database Service, start Teleport with the appropriate configuration.
Note that a single Teleport process can run multiple different services, for
example multiple Database Service agents as well as the SSH Service or Application
Service. The step below will overwrite an existing configuration file, so if
you're running multiple services add --output=stdout
to print the config in
your terminal, and manually adjust /etc/teleport.yaml
.
Generate a configuration file at /etc/teleport.yaml
for the Database Service:
sudo teleport db configure create \ -o file \ --token=/tmp/token \ --proxy=teleport.example.com:443 \ --name=example-postgres \ --protocol=postgres \ --uri=postgres.example.com:5432 \ --labels=env=dev
sudo teleport db configure create \ -o file \ --token=/tmp/token \ --proxy=mytenant.teleport.sh:443 \ --name=example-postgres \ --protocol=postgres \ --uri=postgres.example.com:5432 \ --labels=env=dev
Configure the Teleport Database Service to start automatically when the host boots up by creating a systemd service for it. The instructions depend on how you installed the Teleport Database Service.
On the host where you will run the Teleport Database Service, enable and start Teleport:
sudo systemctl enable teleportsudo systemctl start teleport
On the host where you will run the Teleport Database Service, create a systemd service configuration for Teleport, enable the Teleport service, and start Teleport:
sudo teleport install systemd -o /etc/systemd/system/teleport.servicesudo systemctl enable teleportsudo systemctl start teleport
You can check the status of the Teleport Database Service with systemctl status teleport
and view its logs with journalctl -fu teleport
.
Teleport provides Helm charts for installing the Teleport Database Service in Kubernetes Clusters.
Set up the Teleport Helm repository.
Allow Helm to install charts that are hosted in the Teleport Helm repository:
helm repo add teleport https://charts.releases.teleport.dev
Update the cache of charts from the remote repository:
helm repo update
Install the Teleport Kube Agent into your Kubernetes Cluster with the Teleport Database Service configuration.
JOIN_TOKEN=$(cat /tmp/token)helm install teleport-kube-agent teleport/teleport-kube-agent \ --create-namespace \ --namespace teleport-agent \ --set roles=db \ --set proxyAddr=teleport.example.com:443 \ --set authToken=${JOIN_TOKEN?} \ --set "databases[0].name=example-postgres" \ --set "databases[0].uri=postgres.example.com:5432" \ --set "databases[0].protocol=postgres" \ --set "labels.env=dev" \ --version 14.2.1
Install the Teleport Kube Agent into your Kubernetes Cluster with the Teleport Database Service configuration.
JOIN_TOKEN=$(cat /tmp/token)helm install teleport-kube-agent teleport/teleport-kube-agent \ --create-namespace \ --namespace teleport-agent \ --set roles=db \ --set proxyAddr=mytenant.teleport.sh:443 \ --set authToken=${JOIN_TOKEN?} \ --set "databases[0].name=example-postgres" \ --set "databases[0].uri=postgres.example.com:5432" \ --set "databases[0].protocol=postgres" \ --set "labels.env=dev" \ --version 14.1.3
Make sure that the Teleport agent pod is running. You should see one
teleport-kube-agent
pod with a single ready container:
kubectl -n teleport-agent get podsNAME READY STATUS RESTARTS AGEteleport-kube-agent-0 1/1 Running 0 32s
A single Teleport process can run multiple services, for example multiple Database Service instances as well as other services such the SSH Service or Application Service.
Step 5/5. Connect
Once the Database Service has joined the cluster, log in to see the available databases:
tsh login --proxy=teleport.example.com --user=alicetsh db lsName Description Labels
---------------- ------------------ --------
example-postgres Example PostgreSQL env=dev
tsh login --proxy=mytenant.teleport.sh --user=alicetsh db lsName Description Labels
---------------- ------------------ --------
example-postgres Example PostgreSQL env=dev
Note that you will only be able to see databases your role has access to. See RBAC section for more details.
To retrieve credentials for a database and connect to it:
tsh db connect example-postgres
You can optionally specify the database name and the user to use by default when connecting to the database instance:
tsh db connect --db-user=postgres --db-name=postgres example-postgres
To log out of the database and remove credentials:
Remove credentials for a particular database instance.
tsh db logout example-postgresRemove credentials for all database instances.
tsh db logout
