The integration Nomad with Consul error

Nomad
1

Hi team,
I tried to test the integration Nomad with Consul but it doesn’t work well.

As the environment, there is the state that consul agent and nomad agent are running.

The nomad config file hello-consul.nomad is the below.

job "hello-consul" {
  datacenters = ["dc1"]

  type = "service"

  group "web-server" {
    network {
      port "nginx" {
        static = "80"
      }
    }
    count = 1
    task "nginx" {

      service {
        name = "nginx"
        tags = ["nginx", "nomad"]
        meta {
          meta = "for your service"
        }
        check {
          type     = "http"
          protocol = "http"
          port     = "nginx"
          interval = "10s"
          timeout  = "2s"
          path = "/index.html"
        }
      }

      driver = "docker"

      config {
        image = "nginx"
      }

      resources {
        cpu    = 500
        memory = 256
      }
    }
  }
}

I ran the job file by nomad command, but it failed due to progress deadline.

I checked by the alloc status command, but I didn’t find the cause.

Hi. Check consul website,click on tge nginx service and see the healthcheck.

Probably it is green now, but could have been red on startup.

Hi @Kamilcuk ,

Now I fixed the nomad config, and it worked well.

job "hello-consul" {
  datacenters = ["dc1"]

  type = "service"

  group "web-server" {
    count = 1
    network {
      port "nginx" {
        static = "80"
      }
    }

    service {
        name = "nginx"
        tags = ["nginx", "nomad"]
        meta {
          meta = "for your service"
        }
        check {
          type     = "http"
          port = "nginx"
          interval = "10s"
          timeout  = "2s"
          path = "/index.html"
        }
    }

    task "nginx" {
      driver = "docker"

      config {
        image = "nginx"
        ports = ["nginx"]
      }

      resources {
        cpu    = 500
        memory = 256
      }
    }
  }
}

Thank you so much.
