Wiki.js stores its pages and settings in PostgreSQL. No Service data volume is needed for the basic database-backed installation.

## Towbar manifests

<CodeGroup>
  ```yaml title=".towbar/datastores/wiki-js-postgres.datastore.yml" theme={"system"}
  id: wiki-js-postgres
  name: Wiki.js PostgreSQL
  type: postgres
  container:
    network: application
    networkAlias: wiki-js-postgres
    resources:
      cpus: 1
      memory: 1g
  secrets:
    runtime:
      - POSTGRES_USER
      - POSTGRES_DB
      - POSTGRES_PASSWORD
  environments:
    production:
      server: 192.0.2.10
  ```

  ```yaml title=".towbar/services/wiki-js.service.yml" theme={"system"}

</CodeGroup>

## Configure

1. Prepare the example server, connect the repository, and map `production` to the branch containing these manifests. Replace the example server IP and domain. Commit the manifests, then sync the repository and inspect the resolved configuration.
2. Save the initialization values in the table below for the postgres Datastore under **Datastore → Settings → Secrets**. Deploy it first and wait for readiness. These values create the database and user only on an empty volume.
3. Set the Service's declared runtime values under **Service → Settings → Secrets** using the table below. Replace descriptions and placeholders with actual values; do not commit passwords or keys.
4. Deploy the Service, then perform the checks below before enabling auto-deploy.

## Datastore values

Save these in each Datastore's **Settings → Secrets** before deploying it. Use the suggested names or choose your own, then use the same names and passwords in the Service connection values below.

| Datastore        | Key                 | Suggested value                                                                           |
| ---------------- | ------------------- | ----------------------------------------------------------------------------------------- |
| Wiki.js postgres | `POSTGRES_DB`       | wiki\_js                                                                                  |
| Wiki.js postgres | `POSTGRES_USER`     | wiki\_js                                                                                  |
| Wiki.js postgres | `POSTGRES_PASSWORD` | Run `openssl rand -hex 32`; save its output and reuse it in the Service connection value. |

## Runtime values

Save these values on the Service after the repository sync. The manifest declares required keys, not their values.

| Key       | Value to save                     |
| --------- | --------------------------------- |
| `DB_TYPE` | postgres                          |
| `DB_HOST` | wiki-js-postgres                  |
| `DB_PORT` | 5432                              |
| `DB_NAME` | Same value as POSTGRES\_DB.       |
| `DB_USER` | Same value as POSTGRES\_USER.     |
| `DB_PASS` | Same value as POSTGRES\_PASSWORD. |

## Verify

Complete the installer, publish a test page, and verify it remains after redeployment.
