Pomerium Enterprise Management API

The Pomerium Enterprise Console supports programmatic interaction through a gRPC API. This page covers enabling and authenticating to the API.

Before You Begin

This doc assumes:

• You already have installed Pomerium and Pomerium Enterprise,
• The connection to the enterprise console service is encrypted.

Configure a New Route

1. We suggest configuring the route for API access in the open-source Pomerium. That way changes made through the API that might break access to the console GUI will not break access to the API route.

   - from: https://console-api.pomerium.localhost.io
     to: https://pomerium-console-domain-name:8702
     pass_identity_headers: true
     allow_any_authenticated_user: true
     tls_custom_ca_file: /path/to/rootCA.pem # See https://www.pomerium.com/reference/#tls-custom-certificate-authority

2. You must also update the audience key to include the new route's from value:

   audience: 'console.pomerium.localhost.io,console-api.pomerium.localhost.io'

   If you're running Pomerium Enterprise as a system service, restart the daemon.

Create a Service Account

1. In the enterprise Console under Configure -> Service Accounts, Click + Add Service Account. You can choose an existing user for the service account to impersonate, or create a new user. Note that a new user will not be synced to your IdP.

2. The Enterprise Console will display the service account token. Be sure to store it securely now, as you cannot view it again after this point.

3. Grant the service account the appropriate role on the Namespace(s) it will operate against.

tip

Service accounts created in any Namespace other than Global will include a reference to that Namespace ID. You must specify the entire user ID (i.e. design-api@bff1bea6-a3d6-232d-812c-b4fd8e26d72e.pomerium) when using the service account.

Install The Library

Python

pip3 install git+https://git@github.com/pomerium/enterprise-client-python

Go

go get github.com/pomerium/enterprise-client-go

Test the API Connection

The repositories for our Python and Go implementations include example scripts:

Python

#!/usr/bin/env python

import os
from pomerium.client import Client
from pomerium.pb.policy_pb2 import ListPoliciesRequest
from pomerium.pb.namespaces_pb2 import ListNamespacesRequest
from pomerium.pb.routes_pb2 import SetRouteRequest, Route

# get custom CA and service account credentials from environment
ca_cert = os.getenv('CA_CERT', '').encode('utf-8')
sa = os.getenv('SERVICE_ACCOUNT', '')
console_api = 'console-api.localhost.pomerium.io'

client = Client(console_api, sa, root_certificates=ca_cert)

# get id for namespace 'Production'
resp = client.NamespaceService.ListNamespaces(ListNamespacesRequest())
ns = [n for n in resp.namespaces if n.name == 'Production'][0]

# find policy named 'my policy' in namespace 'Production'
resp = client.PolicyService.ListPolicies(
    ListPoliciesRequest(query='my policy', namespace=ns.id)
)
policy = resp.policies[0]

# set route in namespace 'Production', associated to 'my policy'
route = Route(**{
    'namespace_id': ns.id,
    'name': 'my route',
    'from': 'https://test.localhost.pomerium.io',
    'to': ['https://verify.pomerium.com'],
    'policy_ids': [policy.id],
    'pass_identity_headers': True,
})

resp = client.RouteService.SetRoute(SetRouteRequest(route=route))
print(resp)

        Name:                "my route",
        From:                "https://test.localhost.pomerium.io",
        To:                  []string{"https://verify.pomerium.com"},
        PolicyIds:           []string{policyId},
        PassIdentityHeaders: &passIdHeaders,
    }

    routeResp, err := p.RouteService.SetRoute(ctx, &pb.SetRouteRequest{Route: newRoute})
    if err != nil {
        return fmt.Errorf("could not create route: %w", err)
    }

    fmt.Printf("created route id: %s\n", routeResp.Route.GetId())
    return nil
}

Modify the example script to match your console API path, Namespace(s) and Policy names.
