This page describes the Levelrail template for Remark42 (Productivity). It deploys the services below as one Docker Compose app on your own server. Project site: [https://github.com/umputun/remark42](https://github.com/umputun/remark42).

Recommended memory: about 128 MiB.

## Services, ports and volumes

| Service | Image | Container ports | Volumes |
| - | - | - | - |
| `remark42` | `umputun/remark42:v1.18.0` | 8080 | `data -> /srv/var` |

## Environment variables

| Service | Variable | Value |
| - | - | - |
| `remark42` | `AUTH_ANON` | Preset in the template |
| `remark42` | `BACKUP_PATH` | Preset in the template |
| `remark42` | `REMARK_URL` | Preset in the template |
| `remark42` | `SECRET` | Generated at deploy |
| `remark42` | `SITE` | Preset in the template |
| `remark42` | `STORE_BOLT_PATH` | Preset in the template |

Passwords and keys marked as generated are created for you when the app is deployed and stored as secrets. Values are not shown here.

## Security and requirements

Level: **Standard**.

What this template needs:

* Passwords and keys are generated at deploy time (`remark42`): SECRET.
* Stores data in named volumes (`remark42`): data.

What Levelrail adds around it:

* Automatic HTTPS and an ingress shield in front of every domain.
* Secrets are generated, stored encrypted and masked in logs and the UI.
* Named volumes can be backed up and restored.
* Deploys are gated on the health check before traffic switches.
* One-step rollback to the previous revision.
* Exposure report shows what is reachable from outside.
* Host firewall rules managed for published ports.

## Deploy Remark42 with Levelrail

In the dashboard, open **Apps**, choose **New app**, then **Browse templates**, and select Remark42. Review the Compose body and deploy.

With the CLI:

```bash theme={"dark"}
levelrail-cli templates deploy remark42 --name my-remark42
```
