Teleport Database Access Preview

Teleport Database Access allows organizations to use Teleport as a proxy to provide secure access to their databases while improving both visibility and access control.

To find out whether you can benefit from using Database Access, see if you're facing any of the following challenges in your organization:

If so, Database Access might help you solve some of these challenges.

Info

Teleport Database Access is currently under active development, with a preview release slated for Teleport 5.1 in December 2020. The preview will include support for PostgreSQL, including Amazon RDS and Aurora.

Setup

Let's setup a sample Teleport Database Access deployment.

We will create a Teleport cluster and connect a PostgreSQL-flavored AWS Aurora database to it via Teleport database proxy.

Setup Aurora

Teleport Database Access uses IAM authentication with AWS RDS and Aurora databases which can be enabled with the following steps.

Enable IAM Authentication

Open Amazon RDS console and create a new database instance with IAM authentication enabled, or modify an existing one to turn it on. Make sure to use PostgreSQL database type.

See Enabling and disabling IAM database authentication for more information.

Create IAM Policy

To allow Teleport database service to log into the database instance using auth token, create an IAM policy and attach it to the user whose credentials the database service will be using, for example:

{
   "Version": "2012-10-17",
   "Statement": [
      {
         "Effect": "Allow",
         "Action": [
             "rds-db:connect"
         ],
         "Resource": [
             "arn:aws:rds-db:us-east-2:1234567890:dbuser:cluster-ABCDEFGHIJKL01234/*"
         ]
      }
   ]
}

See Creating and using an IAM policy for IAM database access for more information.

Create Database User

Database users must have a rds_iam role in order to be allowed access. For PostgreSQL:

CREATE USER alice;
GRANT rds_iam TO alice;

See Creating a database account using IAM authentication for more information.

Install Teleport

First, head over to the Teleport downloads page and download the latest version of Teleport.

Warning

As of this writing, no Teleport release with Database Access has been published yet.

Follow the installation instructions.

Start Teleport

Create a configuration file for a Teleport service that will be running auth and proxy servers:

teleport:
  data_dir: /var/lib/teleport
  nodename: test
auth_service:
  enabled: "yes"
  cluster_name: "test"
  listen_addr: 0.0.0.0:3025
  tokens:
  - proxy,node,database:qwe123
proxy_service:
  enabled: "yes"
  listen_addr: 0.0.0.0:3023
  web_listen_addr: 0.0.0.0:3080
  tunnel_listen_addr: 0.0.0.0:3024
  public_addr: teleport.example.com:3080
ssh_service:
  enabled: "no"

Start the service:

$ teleport start --debug --config=/path/to/teleport.yaml

Start Teleport Database Service

Create configuration file for a database service:

teleport:
  data_dir: /var/lib/teleport-db
  nodename: test
  # Auth token to connect to the auth server.
  auth_token: qwe123
  # Proxy address to connect to.
  auth_servers:
  - teleport.example.com:3080
db_service:
  enabled: "yes"
  databases:
    # Name of the database proxy instance, used to reference in CLI.
  - name: "postgres-aurora"
    # Free-form description of the database proxy instance.
    description: "AWS Aurora instance of PostgreSQL 13.0"
    # Database protocol.
    protocol: "postgres"
    # Database address.
    uri: "postgres-aurora-instance-1.xxx.us-east-1.rds.amazonaws.com:5432"
    # AWS specific configuration.
    aws:
      # Region the database is deployed in.
      region: us-east-1
    # Labels to assign to the database, used in RBAC.
    labels:
      env: dev
auth_service:
  enabled: "no"
ssh_service:
  enabled: "no"
proxy_service:
  enabled: "no"

Start the service:

$ teleport start --debug --config=/path/to/teleport-db.yaml

Login

After the setup, log into the cluster and see the registered database proxy:

$ tsh login --proxy=teleport.example.com:3080
$ tsh db ls

Connect

Log into the database and connect using psql:

$ tsh db login postgres
$ psql "service=postgres-aurora user=<db-user> database=<db-name>"
