tailscale and beszel on hashicorp nomad

hey,
i just want it to share with you what i found today: https://tailscale.com/blog/video-beszel

so i deciced to try it on hashicorp nomad and it works great!

here is jobs example:

beszel dashboard

variables {
  domain = "beszel.my.domain.tld"
}

job "beszel-dashboard" {
  datacenters = ["rpi"]

  group "beszel" {
    count = 1

    task "beszel-dashboard" {
      driver = "docker"

      config {
        image = "henrygd/beszel:latest"

        extra_hosts = [
          "host.docker.internal:host-gateway"
        ]
        volumes = [
          "/data/beszel:/beszel_data",
        ]
      }

      resources {
        cpu    = 500
        memory = 1024
      }

      service {
        name = "beszel-dashboard"
        provider     = "nomad"
        address_mode = "driver"
        port = "8090"
        tags = [
          "traefik.enable=true",
          "traefik.http.routers.http-${NOMAD_ALLOC_ID}.entrypoints=web",
          "traefik.http.routers.http-${NOMAD_ALLOC_ID}.rule=Host(`${var.domain}`)",
          "traefik.http.services.http-${NOMAD_ALLOC_ID}.loadbalancer.server.port=8090",
          # "traefik.http.services.https-${NOMAD_ALLOC_ID}.loadbalancer.server.port=8090",
          "traefik.http.routers.https-${NOMAD_ALLOC_ID}.rule=Host(`${var.domain}`)",
          "traefik.http.routers.https-${NOMAD_ALLOC_ID}.entrypoints=websecure",
          "traefik.http.routers.https-${NOMAD_ALLOC_ID}.tls.certresolver=le",
          "traefik.http.routers.https-${NOMAD_ALLOC_ID}.tls=true"
        ]
      }
    }
  }
}

and system job for agents:

job "beszel-agent" {
  datacenters = ["*"]
  type        = "system"

  meta {
    version = "2"
  }


  group "beszel" {
    count = 1

    network {
      mode = "host"
      port "http" {
        host_network = "tailscale"
        static       = 45876
      }
    }

    task "beszel-agent" {
      driver = "docker"

      config {
        image        = "henrygd/beszel-agent:latest"
        volumes      = ["/var/run/docker.sock:/var/run/docker.sock:ro"]
        ports        = ["http"]
      }
      env {
        PORT = "45876"
        KEY  = "<your key from dashboard here>"
      }
    }
  }
}

each new host gets its own agent on port, so you can add that IP to your beszel dashboard.

and thats it.
