Set up a PostgreSQL connector

C1 provides identity governance and just-in-time provisioning for PostgreSQL. Integrate your PostgreSQL instance with C1 to run user access reviews (UARs) and enable just-in-time access requests.

The PostgreSQL connector supports automatic account provisioning and deprovisioning.

When a new account is created by C1, the account’s password will be sent to a vault.

Gather PostgreSQL credentials

Configuring the connector requires you to pass in credentials generated in PostgreSQL. Gather these credentials before you move on.

• The DSN used to connect to the PostgreSQL database

Done. Next, move on to the connector configuration instructions.

Configure the PostgreSQL connector

To complete this task, you’ll need:

• The Connector Administrator or Super Administrator role in C1
• Access to the set of PostgreSQL credentials generated by following the instructions above

Cloud-hosted

Follow these instructions to use a built-in, no-code connector hosted by C1.

Cloud-hosted connector not currently available.

Self-hosted

Follow these instructions to use the PostgreSQL connector, hosted and run in your own environment.

When running in service mode on Kubernetes, a self-hosted connector maintains an ongoing connection with C1, automatically syncing and uploading data at regular intervals. This data is immediately available in the C1 UI for access reviews and access requests.

Resources

• Official download center: For stable binaries (Windows/Linux/macOS) and container images.

• GitHub repository: Access the source code, report issues, or contribute to the project.

Step 1: Set up a new PostgreSQL connector

1. In C1, navigate to Integrations > Connectors > Add connector.

2. Search for Baton and click Add.

3. Choose how to set up the new PostgreSQL connector:

   • Add the connector to a currently unmanaged app (select from the list of apps that were discovered in your identity, SSO, or federation provider that aren’t yet managed with C1)

   • Add the connector to a managed app (select from the list of existing managed apps)

   • Create a new managed app

4. Set the owner for this connector. You can manage the connector yourself, or choose someone else from the list of C1 users. Setting multiple owners is allowed.

   If you choose someone else, C1 will notify the new connector owner by email that their help is needed to complete the setup process.

5. Click Next.

6. In the Settings area of the page, click Edit.

7. Click Rotate to generate a new Client ID and Secret.

   Carefully copy and save these credentials. We’ll use them in Step 2.

Step 2: Create Kubernetes configuration files

Create two Kubernetes manifest files for your PostgreSQL connector deployment:

Secrets configuration

# baton-postgresql-secrets.yaml
apiVersion: v1
kind: Secret
metadata:
  name: baton-postgresql-secrets
type: Opaque
stringData:
  # C1 credentials
  BATON_CLIENT_ID: <C1 client ID>
  BATON_CLIENT_SECRET: <C1 client secret>
  
  # PostgreSQL credentials
  BATON_DSN: <PostgreSQL DSN used to connect to the database>
  BATON_SCHEMAS: <The schemas to include in the sync (default is "public")>

  # Optional: Include if you want to sync these data-intensive resources 
  BATON_INCLUDE_COLUMNS: true
  BATON_INCLUDE_LARGE_OBJECTS: true

  # Optional: include if you want C1 to provision access using this connector
  BATON_PROVISIONING: true

See the connector’s README or run --help to see all available configuration flags and environment variables.

Deployment configuration

# baton-postgresql.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: baton-postgresql
  labels:
    app: baton-postgresql
spec:
  selector:
    matchLabels:
      app: baton-postgresql
  template:
    metadata:
      labels:
        app: baton-postgresql
        baton: true
        baton-app: postgresql
    spec:
      containers:
      - name: baton-postgresql
        image: ghcr.io/conductorone/baton-postgresql:latest
        imagePullPolicy: IfNotPresent
        env:
        - name: BATON_HOST_ID
          value: baton-postgresql
        envFrom:
        - secretRef:
            name: baton-postgresql-secrets

Step 3: Deploy the connector

1. Create a namespace in which to run C1 connectors (if desired), then apply the secret config and deployment config files.

2. Check that the connector data uploaded correctly. In C1, click Apps. On the Managed apps tab, locate and click the name of the application you added the PostgreSQL connector to. PostgreSQL data should be found on the Entitlements and Accounts tabs.

Done. Your PostgreSQL connector is now pulling access data into C1.
