::note
🎯 __Objectives:__

- Install Beszel
- Monitor the local server
- Monitor a remote server
- Expose Beszel with Swag
::

[Beszel](https://beszel.dev/) is a container that gives you real-time access to hardware information from your servers and allows historical tracking. CPU activity, disk usage, temperatures, RAM: nothing escapes your monitoring. Beszel also lets you configure notifications and alerts when your predefined thresholds are exceeded.

Beszel includes a hub with a web UI and an agent that collects data from your server or a remote server.

## Installation

Folder structure

```text [Directory tree]
root
└── docker
    └── beszel
        ├── data
        └── socket
```

Open Dockge, click `compose`, name the stack `beszel`, and paste the following:

```yaml [compose.yaml]
---
services:
  beszel:
    image: henrygd/beszel:latest
    container_name: beszel
    restart: unless-stopped
    ports:

      - ${PORT}:8090
    volumes:

      - ./data:/beszel_data
      - ./socket:/beszel_socket

  beszel-agent:
    image: henrygd/beszel-agent:latest
    container_name: beszel-agent
    restart: unless-stopped
    network_mode: host
    volumes:

      - ./socket:/beszel_socket
      - /var/run/docker.sock:/var/run/docker.sock:ro
    environment:
      LISTEN: /beszel_socket/beszel.sock
      # Do not remove quotes around the key
      KEY: ${KEY}
```

✨ __Tip:__ Add the Watchtower label to each container to automate updates.

```yaml [compose.yaml]
services:
  beszel:
    #...
    labels:

      - com.centurylinklabs.watchtower.enable=true
```
::

Fill out the `.env` file, for example:

```properties [.env]
PORT=8090 # web UI port
KEY= # private key to retrieve from Beszel when adding a system
```

For the `KEY` value, you'll need to launch Beszel once to get it.

Deploy the container and go to `http://yourserverip:8090`. Your Beszel web UI is now accessible!

::caution

__If it fails:__ check your firewall rules.
::

### Add local server information

Now that the web UI is accessible, you need to push local server information into it. Just add a machine via the web UI and configure it like this:

![Beszel add system](/img/serveex/beszel-add.png)

Note the private key and confirm. Enter the key in your `.env` file in Dockge and redeploy the stack. Once done, your server will appear in the web UI:

![Beszel system](/img/serveex/beszel-system.png)

### Add a remote server

You can also monitor a remote server. To do so, run the agent on the remote server. Add a new machine in Beszel and fill in:

- The name displayed for your remote server
- The IP address or domain name of the remote server
- The listening port (e.g., `45876`)

Beszel will suggest a `compose.yaml` to deploy on the remote server, or you can use:

```yaml [compose.yaml]
---
services:
  beszel-agent:
    image: henrygd/beszel-agent
    container_name: beszel-agent
    restart: unless-stopped
    network_mode: host
    volumes:

      - /var/run/docker.sock:/var/run/docker.sock:ro
    environment:
      LISTEN: ${PORT}
      KEY: ${KEY}
```

And in `.env`:

```properties [.env]
PORT=45876 # communication port between hub and remote agent
KEY= # private key from Beszel when adding the system
```

Deploy the stack on the remote server. Data will begin flowing into the web UI after a few seconds.

::caution

__If it fails:__ check your firewall rules.
::

## Expose Beszel with Swag

::warning

Beszel does not support multi-factor authentication. Exposing it on the internet could compromise connected machines. Only do this if you're using a system like [Authentik](/serveex/advanced/authentik/). Otherwise, do not expose with SWAG. Use a VPN like [Wireguard](/serveex/security/wireguard) instead.
::

If you want to access Beszel remotely from all your devices, expose it using Swag.

::note
📋 __Prerequisite:__
<br/><br/>
You must have created a DNS subdomain like `beszel.mydomain.com` with a `CNAME` pointing to `mydomain.com`. Unless you're using Cloudflare Zero Trust, you must also have forwarded port `443` on your router to your server’s `443` port via [NAT rules](/general/networking/nat).
::

In Dockge, edit Swag's compose file and add Beszel’s network:

```yaml [compose.yaml]
services:
  swag:
     container_name: # ...
      # ...
     networks:
      # ...

      - beszel            # network declared in the stack

networks:
  # ...
  beszel:
    name: beszel_default  # actual external network name
    external: true
```

Redeploy the stack and wait for Swag to become fully operational.

::note

We assume the network name is `beszel_default`. You can check connectivity by visiting Swag's dashboard at `http://yourserverip:81`.
::

In Swag’s config folders, create `beszel.subdomain.conf`.

✨ __Tip:__ Use [File Browser](/serveex/files/file-browser) to browse and edit files instead of terminal commands.
::

```bash [Terminal]
sudo nano /docker/swag/config/nginx/proxy-confs/beszel.subdomain.conf
```

Paste:

```nginx [beszel.subdomain.conf]
## Version 2023/12/19

server {
    listen 443 ssl;
    listen [::]:443 ssl;

    server_name beszel.*;

    include /config/nginx/ssl.conf;

    client_max_body_size 0;

    #if ($lan-ip = yes) { set $geo-whitelist yes; }
    #if ($geo-whitelist = no) { return 404; }
    if ($geo-blacklist = no) { return 404; }

    # enable for ldap auth
    #include /config/nginx/ldap-server.conf;

    # enable for Authelia
    #include /config/nginx/authelia-server.conf;

    # enable for Authentik
    #include /config/nginx/authentik-server.conf;

    location / {
        #auth_basic "Restricted";
        #auth_basic_user_file /config/nginx/.htpasswd;

        #include /config/nginx/ldap-location.conf;
        #include /config/nginx/authelia-location.conf;
        #include /config/nginx/authentik-location.conf;

        include /config/nginx/proxy.conf;
        include /config/nginx/resolver.conf;
        set $upstream_app beszel;
        set $upstream_port 8090;
        set $upstream_proto http;
        proxy_pass $upstream_proto://$upstream_app:$upstream_port;
    }
}
```

Press :kbd{value="Ctrl+O"}, then :kbd{value="Enter"} to save, and :kbd{value="Ctrl+X"} to exit.

That’s it! Beszel is now exposed!

::tip
✨ You can protect this app with [TinyAuth](/serveex/security/tinyauth) and [Pocket ID](/serveex/security/pocket-id) using the reverse-proxy pattern from the TinyAuth guide, or with Authentik by opening `beszel.subdomain.conf` and removing the `#` in front of `include /config/nginx/authentik-server.conf;` and `include /config/nginx/authentik-location.conf;`. Don’t forget to [create an application and provider in Authentik](/serveex/advanced/authentik#protecting-an-app-via-reverse-proxy).
