Teleport

Database Access with Redis

  • Available for:
  • OpenSource
  • Enterprise
  • Cloud

If you want to configure Redis Cluster, please read Database Access with Redis Cluster.

Teleport can provide secure access to Redis via the Teleport Database Service. This allows for fine-grained access control through Teleport's RBAC.

In this guide, you will:

  1. Configure an Redis database with mutual TLS authentication.
  2. Join the Redis database to your Teleport cluster.
  3. Connect to the Redis database via the Teleport Database Service.

Prerequisites

  • A running Teleport cluster. For details on how to set this up, see the Getting Started guide.

  • The tctl admin tool and tsh client tool version >= 15.1.10.

    See Installation for details.

To check version information, run the tctl version and tsh version commands. For example:

tctl version

Teleport v15.1.10 git:api/14.0.0-gd1e081e go1.21

tsh version

Teleport v15.1.10 go1.21

Proxy version: 15.1.10Proxy: teleport.example.com
  • A running Teleport Enterprise cluster. For details on how to set this up, see the Enterprise Getting Started guide.

  • The Enterprise tctl admin tool and tsh client tool version >= 15.1.10.

    You can download these tools by visiting your Teleport account workspace.

To check version information, run the tctl version and tsh version commands. For example:

tctl version

Teleport Enterprise v15.1.10 git:api/14.0.0-gd1e081e go1.21

tsh version

Teleport v15.1.10 go1.21

Proxy version: 15.1.10Proxy: teleport.example.com
  • A Teleport Enterprise Cloud account. If you don't have an account, sign up to begin a free trial.

  • The Enterprise tctl admin tool and tsh client tool version >= 15.1.9.

    You can download these tools from the Cloud Downloads page.

To check version information, run the tctl version and tsh version commands. For example:

tctl version

Teleport Enterprise v15.1.9 git:api/14.0.0-gd1e081e go1.21

tsh version

Teleport v15.1.9 go1.21

Proxy version: 15.1.9Proxy: teleport.example.com
  • Redis version 6.0 or newer.

    Note

    RESP3 (REdis Serialization Protocol) is currently not supported.

  • redis-cli version 6.2 or newer installed and added to your system's PATH environment variable.

  • A host where you will run the Teleport Database Service.

    See Installation for details.

  • To check that you can connect to your Teleport cluster, sign in with tsh login, then verify that you can run tctl commands using your current credentials. tctl is supported on macOS and Linux machines.

    For example:

    tsh login --proxy=teleport.example.com --user=[email protected]
    tctl status

    Cluster teleport.example.com

    Version 15.1.10

    CA pin sha256:abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678abdc1245efgh5678

    If you can connect to the cluster and run the tctl status command, you can use your current credentials to run subsequent tctl commands from your workstation. If you host your own Teleport cluster, you can also run tctl commands on the computer that hosts the Teleport Auth Service for full permissions.

Step 1/5. Set up the Teleport Database Service

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

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.

Before installing a teleport binary with a version besides v15, read our compatibility rules to ensure that the binary is compatible with Teleport Enterprise Cloud.

Teleport uses Semantic Versioning. Version numbers include a major version, minor version, and patch version, separated by dots. 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 one major version behind, but do not support clients that are on a newer major version. For example, an 8.x.x Proxy Service instance is compatible with 7.x.x agents and 7.x.x tsh, but we don't guarantee that a 9.x.x agent will work with an 8.x.x Proxy Service instance. 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 Service instances and agents do not support Auth Service instances that are on an older major version, and will fail to connect to older Auth Service instances by default. You can override version checks by passing --skip-version-check when starting agents and Proxy Service instances.

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-redis \ --protocol=redis \ --uri=rediss://redis.example.com:6379 \ --labels=env=dev
sudo teleport db configure create \ -o file \ --token=/tmp/token \ --proxy=mytenant.teleport.sh:443 \ --name=example-redis \ --protocol=redis \ --uri=rediss://redis.example.com:6379 \ --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 teleport
sudo 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.service
sudo systemctl enable teleport
sudo 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 so you can upgrade to all available releases:

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-redis" \ --set "databases[0].uri=rediss://redis.example.com:6379" \ --set "databases[0].protocol=redis" \ --set "labels.env=dev" \ --version 15.1.10

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-redis" \ --set "databases[0].uri=rediss://redis.example.com:6379" \ --set "databases[0].protocol=redis" \ --set "labels.env=dev" \ --version 15.1.9

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 pods
NAME READY STATUS RESTARTS AGEteleport-kube-agent-0 1/1 Running 0 32s
Tip

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 2/5. Create a Teleport user

Tip

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
FlagDescription
--rolesList of roles to assign to the user. The builtin access role allows them to connect to any database server registered with Teleport.
--db-usersList of database usernames the user will be allowed to use when connecting to the databases. A wildcard allows any user.
--db-namesList of logical databases (aka schemas) the user will be allowed to connect to within a database server. A wildcard allows any database.
Warning

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 3/5. Create Redis users

Each Redis user must be protected by a strong password. We recommend using OpenSSL to generate passwords:

openssl rand -hex 32
Note

If you have access to Redis you can also generate a password by using the below command from the Redis console:

ACL GENPASS

Create a users.acl file, which defines users for your Redis deployment, passwords required to log in as a given user, and sets of ACL rules. Redis allows you to provide passwords in plaintext or an SHA256 hash. We strongly recommend using an SHA256 hash instead of plaintext passwords.

You can use the command below to generate an SHA256 hash from a password.

echo -n STRONG_GENERATED_PASSWORD | sha256sum
user alice on #57639ed88a85996453555f22f5aa4147b4c9614056585d931e5d976f610651e9 allcommands allkeys
user default off

For more ACL examples refer to the Redis documentation.

Warning

It's very important to either disable or protect with a password the default user. Otherwise, everyone with access to the database can log in as the default user, which by default has administrator privileges.

Step 4/5. Set up mutual TLS

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"]

We will show you how to use tctl auth sign below.

When connecting to standalone Redis, sign the certificate for the hostname over which Teleport will be connecting to it.

For example, if your Redis server is accessible at redis.example.com, run:

tctl auth sign --format=redis --host=redis.example.com --out=server --ttl=2190h
TTL

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 three files:

  • server.cas with Teleport's certificate authority
  • server.key with a generated private key
  • server.crt with a generated user certificate

You will need these files to enable mutual TLS on your Redis server.

Use the generated secrets to enable mutual TLS in your redis.conf configuration file and restart the database:

tls-port 6379
port 0
aclfile /path/to/users.acl
tls-ca-cert-file /path/to/server.cas
tls-cert-file /path/to/server.crt
tls-key-file /path/to/server.key
tls-protocols "TLSv1.2 TLSv1.3"

Once mutual TLS has been enabled, you will no longer be able to connect to the cluster without providing a valid client certificate. You can use the tls-auth-clients optional setting to allow connections from clients that do not present a certificate.

See TLS Support in the Redis documentation for more details.

Step 5/5. Connect

Log into your Teleport cluster and see available databases:

tsh login --proxy=teleport.example.com --user=alice
tsh db ls

Name Description Labels

------------- --------------- --------

example-redis Example Redis env=dev

tsh login --proxy=mytenant.teleport.sh --user=alice
tsh db ls

Name Description Labels

------------- --------------- --------

example-redis Example Redis env=dev

To connect to a particular database instance:

tsh db connect example-redis

You can optionally specify the database user to use by default when connecting to the database instance:

tsh db connect --db-user=alice example-redis

If flag --db-user is not provided, Teleport logs in as the default user.

Now you can log in as the previously created user using the below command:

AUTH alice STRONG_GENERATED_PASSWORD

To log out of the database and remove credentials:

Remove credentials for a particular database instance.

tsh db logout example-redis

Remove credentials for all database instances.

tsh db logout

Supported Redis commands

Redis in standalone mode doesn't support the commands below. If one of the listed commands is called Teleport returns the ERR Teleport: not supported by Teleport error.

  • HELLO
  • PUNSUBSCRIBE
  • SSUBSCRIBE
  • SUNSUBSCRIBE
