How to correctly reference another task

Nomad
1

I am trying to deploy KongHQ, with a Postgres DB.

I have postgres already working with a persistent volume (host), but i cannot seem to get kong migration to interact with the postgres db.

The following is the code,

Please correct me!

job "postgres-kong-server" {
  datacenters = ["dc1"]
  type        = "service"

  group "postgres-kong-server" {
    count = 1

    volume "postgres" {
      type      = "host"
      read_only = false
      source    = "postgres"
    }

    restart {
      attempts = 10
      interval = "5m"
      delay    = "25s"
      mode     = "delay"
    }

    task "postgres-kong-server" {
      driver = "docker"

      volume_mount {
        volume      = "postgres"
        destination = "/var/lib/postgresql/data"
        read_only   = false
      }

      env = {
        "POSTGRES_PASSWORD" = "xxxx"
        "POSTGRES_DB"       = "kong"
        "POSTGRES_USER"     = "kong"
      }

      config {
        image = "postgres:12.2"

        port_map {
          db = 5432
        }
      }

      resources {
        cpu    = 500
        memory = 1024

        network {
          port "db" {
            static = 5432
          }
        }
      }

      service {
        name = "postgres-kong-server"
        port = "db"

        check {
          type     = "tcp"
          interval = "10s"
          timeout  = "2s"
        }
      }
    }
  }

  group "kong-server" {
    count = 1

    task "kong-migrations" {
      driver = "docker"

      env {
        KONG_DATABASE     = "postgres"
        KONG_PG_DATABASE  = "kong"
        KONG_PG_HOST      = "${NOMAD_ADDR_postgres_kong_server_db}"
        KONG_PG_USER      = "kong"
        KONG_PG_PASSWORD  = "xxxx"
      }

      config {
        image = "kong:2.2-alpine"
        command = "kong"
        args = [
          "migrations",
          "bootstrap",
        ]
      }

      resources {
        cpu    = 500
        memory = 1024
      }
    }
  }
}

The other thing is that i want to run several commands on the database using kong to boostrap it. What would be the best approach? Create a new job and use batch?

Consul-template solved my issue with reference a service. Batch job solved my issue for migrating Kong.
