Sombra Helm Charts

Official Helm charts to deploy Sombra and related services into a Kubernetes cluster.

Deploying with Helm

Make sure you have a working Kubernetes cluster.

Add the Helm repo

helm repo add sombra_chart https://transcend-io.github.io/sombra-helm-chart/

To configure the chart and provide environment variables, create a values.yaml file:

Note: This example of values.yaml assumes you have deployed (A) a working Kubernetes cluster, and (B) an alb AWS application load balancer ingress controller.

Install the package:

helm install some-release sombra-chart/sombra -f ~/values.yaml

To upgrade the package after customization:

helm upgrade some-release sombra-chart/sombra -f ~/values.yaml

To uninstall a release:

helm uninstall some-release

Deployment examples

The following are sample values.yaml files for deploying Sombra in an AWS EKS cluster with different configurations. AWS is not a requirement—Kubernetes can run on any cloud—but AWS is used in these examples for illustrative purposes.

Each example assumes you have deployed (A) a working Kubernetes cluster, and (B) an alb AWS application load balancer ingress controller.
In each example, we are exposing Sombra's sombra-transcend-ingress server (for communication with Transcend through an internet-facing load balancer) and Sombra's sombra-customer-ingress server (for communication with internal services through an internal load balancer).

Deploying Sombra without TLS

TLS can be terminated at the load balancer, or at Sombra's server. In this example, TLS is terminated at the load balancer.

Configuring Sombra

The following is a list of enviroment variables supported by Sombra for its configuration. Please check out our detailed guide on self-hosting Sombra.

Variables	Required	default	secret	Description
ORGANIZATION_URI	yes	N/A	no	This value can be found under "Sombra Audience" here: https://app.transcend.io/infrastructure/sombra/sombras
SOMBRA_ID	no	N/A	no	The SOMBRA_ID parameter is only required when deploying multiple Sombra gateways. This value can be found under "ID" here: https://app.transcend.io/infrastructure/sombra/sombras.
EMPLOYEE_AUTHENTICATION_METHODS	yes	N/A	no	We recommend starting with the 'transcend' authentication method. After Single Sign On is setup, 'transcend' can be switched to 'saml'.
DATA_SUBJECT_AUTHENTICATION_METHODS	yes	N/A	no	We recommend starting with the 'transcend' authentication method. After Account Login is setup, 'transcend' can be switched to 'oauth' or 'jwt'.
JWT_ECDSA_KEY	yes	N/A	yes	The root secrets that you should generate yourself and keep secret. If you are migrating from a Transcend-hosted multi-tenant Sombra to an on-premise and are mid-implementation, it is critical that you re-use the same JWT_ECDSA_KEY from the existing instance. If you already have connected integrations and DSRs, you should deploy the on premise Sombra gateway with the same JWT_ECDSA_KEY and then run a key rotation after the gateway is deployed. To obtain the JWT_ECDSA_KEY reach out to your account manager over Slack or email [email protected] to grant access for you to download the key. You will only be able to reveal the key once for security reasons. The key can be obtained by clicking the Reveal Multi Tenant Root Secret button on the Sombra Gateways panel in the Admin UI.
JWT_AUTHENTICATION_PUBLIC_KEY	no	N/A	no	Company's data subject authentication via JWT public key(s). First entry is latest.

INTERNAL_KEY_HASH	yes	N/A	yes	The hash of a randomly-generated API key that will be used to verify incoming requests from your internal systems. You can use this guide for the generation of key.
SAML_ENTRYPOINT	no	N/A	no	Identity provider entrypoint (is required to be spec-compliant when the request is signed).
SAML_ISSUER	no	`transcend`	no	Issuer string to supply to identity provider.
SAML_CERT	no	N/A	no	The public key to validate the SAML assertion against. The "BEGIN CERTIFICATE" and "END CERTIFICATE" lines should be stripped out and the certificate should be provided on a single line.

OAUTH_GET_CORE_ID_PATH	yes if you configured oauth as one of the DATA_SUBJECT_AUTHENTICATION_METHODS	N/A	no	A path to the coreIdentifier (User ID) to traverse a JSON body (path.to.user.id).
OAUTH_GET_CORE_ID_DATA_SUBJECT_TYPE	yes if you configured oauth as one of the DATA_SUBJECT_AUTHENTICATION_METHODS	N/A	no	The type of Data Subject that the OAuth configuration refers to. This should use the Data Subject slug, which is the value found in parentheses under DSR Automation -> Request Settings -> Data Subjects.
OAUTH_GET_PROFILE_PICTURE_URL	no	N/A	no	Configuration to retrieve additional profile data for the data subject (e.g. nickname, picture).

SOMBRA_TLS_CERT	yes, if you want encrypted traffic b/w Sombra and the load balancer.	N/A	yes	The TLS certificate for this server, base64-encoded in PEM format.
TRUSTED_CLIENT_CA_CERT_ENCODED	no	N/A	yes	The public CA cert from a client who is connecting to the internal Sombra over mutual TLS. If set, Sombra will enforce that all incoming requests to non-health routes have a client cert.

Configure a service to use Pathfinder

For any call to OpenAI, configure your service to use Pathfinder instead by using <your.pathfinder.domain>/api/open-ai instead of the OpenAI base host. Individual endpoints can be appended to this base. For example, https://api.openai.com/v1/chat/completions becomes <your.pathfinder.domain>/api/open-ai/v1/chat/completions.

If you set REQUIRE_AUTHENTICATION to true in your env file, you will also need to add an Authentication header to any API calls to Pathfinder. For example,

{
  headers: {
    // AUTHENTICATION_KEY is the key output in the Generating Keys section above
    Authentication: 'Bearer <AUTHENTICATION_KEY>';
  }
}
