Federating Amazon Redshift Access using Teleport

Length: 08:11

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

In this guide, you will:

Configure an AWS Redshift database with IAM authentication.
Join the AWS Redshift database to your Teleport cluster.
Connect to the AWS Redshift database via the Teleport Database Service.

Cloud is not available for Teleport v.
Please use the latest version of Teleport Enterprise documentation.

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 >= 14.0.0.

See Installation for details.

A Teleport Team account. If you don't have an account, sign up to begin your free trial.
The Enterprise tctl admin tool and tsh client tool, version >= 13.3.9.

You can download these tools from the Cloud Downloads page.

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 >= 14.0.0.

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

Cloud is not available for Teleport v.
Please use the latest version of Teleport Enterprise documentation.

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

tctl version
Teleport Enterprise v13.3.9 git:api/14.0.0-gd1e081e go1.21

tsh version
Teleport v13.3.9 go1.21
Proxy version: 13.3.9Proxy: teleport.example.com

AWS account with a Redshift cluster and permissions to create and attach IAM policies.
Command-line client psql installed and added to your system's PATH environment variable.
A host, e.g., an EC2 instance, where you will run the Teleport Database Service.
A running Teleport Discovery Service if you plan to use Database Auto-Discovery.
To check that you can connect to your Teleport cluster, sign in with tsh login, then verify that you can run tctl commands on your administrative workstation using your current credentials. For example:
```
tsh login --proxy=teleport.example.com --user=[email protected]
tctl status
Cluster  teleport.example.com
Version  14.0.0
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. 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

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.

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 2/5. Create a Database Service configuration

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

For users with a lot of infrastructure in AWS, or who might create or recreate many instances, consider alternative methods for joining new EC2 instances running Teleport:

Install Teleport on the host where you will run the Teleport Database Service:

Select an edition, then follow the instructions for that edition to install Teleport.

Teleport Edition

curl https://goteleport.com/static/install.sh | bash -s 14.0.0

Add the Teleport repository to your repository list:

Download Teleport's PGP public key
sudo curl https://apt.releases.teleport.dev/gpg \-o /usr/share/keyrings/teleport-archive-keyring.asc
Source variables about OS version
source /etc/os-release
Add the Teleport APT repository for cloud.
echo "deb [signed-by=/usr/share/keyrings/teleport-archive-keyring.asc] \https://apt.releases.teleport.dev/${ID?} ${VERSION_CODENAME?} stable/cloud" \| sudo tee /etc/apt/sources.list.d/teleport.list > /dev/null

sudo apt-get update
sudo apt-get install teleport-ent-updater

Source variables about OS version
source /etc/os-release
Add the Teleport YUM repository for cloud.
First, get the OS major version from $VERSION_ID so this fetches the correct
package version.
VERSION_ID=$(echo $VERSION_ID | grep -Eo "^[0-9]+")
sudo yum-config-manager --add-repo "$(rpm --eval "https://yum.releases.teleport.dev/$ID/$VERSION_ID/Teleport/%{_arch}/stable/cloud/teleport-yum.repo")"
sudo yum install teleport-ent-updater
Tip: Add /usr/local/bin to path used by sudo (so 'sudo tctl users add' will work as per the docs)
echo "Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin" > /etc/sudoers.d/secure_path

Source variables about OS version
source /etc/os-release
Add the Teleport YUM repository for cloud.
First, get the OS major version from $VERSION_ID so this fetches the correct
package version.
VERSION_ID=$(echo $VERSION_ID | grep -Eo "^[0-9]+")
Use the dnf config manager plugin to add the teleport RPM repo
sudo dnf config-manager --add-repo "$(rpm --eval "https://yum.releases.teleport.dev/$ID/$VERSION_ID/Teleport/%{_arch}/stable/cloud/teleport-yum.repo")"

Install teleport
sudo dnf install teleport-ent-updater

Tip: Add /usr/local/bin to path used by sudo (so 'sudo tctl users add' will work as per the docs)
echo "Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin" > /etc/sudoers.d/secure_path

Source variables about OS version
source /etc/os-release
Add the Teleport Zypper repository for cloud.
First, get the OS major version from $VERSION_ID so this fetches the correct
package version.
VERSION_ID=$(echo $VERSION_ID | grep -Eo "^[0-9]+")
Use Zypper to add the teleport RPM repo
sudo zypper addrepo --refresh --repo $(rpm --eval "https://zypper.releases.teleport.dev/$ID/$VERSION_ID/Teleport/%{_arch}/stable/cloud/teleport-zypper.repo")

Install teleport
sudo zypper install teleport-ent-updater

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 v13, 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.
