Table: tailscale_acl_derp_map - Query Tailscale ACL Derp Maps using SQL

Tailscale is a secure network connectivity tool that uses WireGuard protocol to create a mesh network of devices. It includes an Access Control List (ACL) feature that helps in managing permissions and secure network connections. The Derp Map in Tailscale represents the network map of all the Tailscale nodes connected over the internet.

Table Usage Guide

The tailscale_acl_derp_map table provides insights into the ACL rules and their network connections in Tailscale. As a Network Administrator, you can use this table to explore details of each Derp Map, including the network nodes and their connections. This can be particularly useful for managing and troubleshooting network issues, ensuring secure and efficient network communications.

Examples

Basic Info

Explore which regions have been omitted in the default settings and understand the corresponding tailnet names. This can be useful for managing and optimizing network routing in a Tailscale network.

  regions,
  tailnet_name
from
  tailscale_acl_derp_map;

select
  omit_default_regions,
  regions,
  tailnet_name
from

This table is available as a standalone Exporter CLI. Steampipe exporters are stand-alone binaries that allow you to extract data using Steampipe plugins without a database.

You can download the tarball for your platform from the Releases page, but it is simplest to install them with the steampipe_export_installer.sh script:

/bin/sh -c "$(curl -fsSL https://steampipe.io/install/export.sh)" -- tailscale

You can pass the configuration to the command with the --config argument:

steampipe_export_tailscale --config '<your_config>' tailscale_acl_derp_map
