GCS Storage Implementation for Teleport

Introduction

This package enables Teleport auth server to store session recordings in GCS on GCP.

WARNING: Using GCS involves recurring charge from GCP.

Building

GCS session storage is not enabled by default. To enable it you have to compile Teleport with gcs build flag.

To build Teleport with GCS enabled, run:

ADDFLAGS='-tags gcs' make teleport

Quick Start

Configuration options are passed to the GCS handler via a URI/URL. The following is a sample configuration in teleport section of the config file (by default it's /etc/teleport.yaml):

yaml

teleport:
  storage:
    audit_sessions_uri: 'gs://teleport-session-storage-2?projectID=gcp-proj&credentialsPath=/var/lib/teleport/gcs_creds'

Full Properties

The full list of configurable properties for this backend are:

host portion of URI is the GCS bucket used to persist session recordings
credentialsPath (string, path to GCP creds for Firestore, not-required)
projectID (string, project ID, required)
endpoint (string, GCS client endpoint, not-required, ex: localhost:8618)
path (string, the path inside the GCS bucket to use as storage root, not-required)
keyName (string, the user-defined GCP KMS key name to use for encryption, not-required)

GCS Client Authentication Options

There are three authentication/authorization modes available;

With no credentialsPath and no endpoint defined, the GCS client will use Google Application Default Credentials for authentication. This only works in cases where Teleport is installed on GCE instances and have service accounts with IAM role/profile associations authorizing that GCE instance to use Firestore.
With endpoint defined, GCS will create a client with no auth and clients pointed at the specified endpoint. This is only used for tests, see Tests section below.
With credentialsPath defined, Firestore will create clients authenticating against live systems with the Service Account bound to the JSON key file referenced in the option.
