Database

In this example, we will use a Valkey server as the storage database. The Redis data will be stored in the directory /data/valkey-data.

Valkey Job Configuration

Below is the Nomad job specification for deploying the Valkey server:

valkey.hcl 
job "valkey" {
  group "cache" {
    network {
      port "valkey" {
        to = 6379
        static = 6379
      }
    }

    task "valkey" {
      driver = "docker"
      config {
        image = "valkey/valkey:8.1"
        ports = [ "valkey" ]

        mounts {
          type = "bind"
          source = "/data/valkey-data"
          target = "/data"
        }
      }
    }

    service {
      name = "valkey"
      port = "valkey"

      check {
        name     = "valkey_check"
        type     = "tcp"
        interval = "10s"
        timeout  = "5s"
      }
    }
  }
}

Steps to Deploy

  1. Create the Data Directory Ensure the directory for storing Valkey data exists by running:

    mkdir -p /data/valkey-data

  2. Deploy the Job to Nomad Use the following command to deploy the Valkey job:

    nomad run valkey.hcl
