Nomad examples?

[Long Nguyen]

Hi all,

   Does anyone have good nomad job examples? I'm a hard time trying to get some basic things like postgres up and running. (https://gist.github.com/lnguyen/03e46a0cbfbaa5b341dbb113000365df). Looking for templates examples and connecting services examples as well.

Thanks,

Long

Hey,

There are a few examples here: https://github.com/jippi/awesome-nomad/blob/master/zookeeper/zookeeper.hcl

You can also run `nomad init` which will output an example job for reference.

Thanks,
Alex Dadgar

Hi,Alex

   I see these examples through following link that you provided ,but I change to it as my own scripts,you can see it as follows

 job "nginx" {

    region = "office"

    datacenters = ["west"]

    type = "service"

    all_at_once = false

    group "nginx" {

        count = 1

        restart {

            attempts = 10

            delay = "15s"

            interval = "5m"

            mode = "delay"

        }

        # Create service using a docker image

task "nginx-ck" {

    driver = "exec"

           config {

               command = "tail"

               args = ["-f", "/dev/null"]

           }

           resources {

                   network {

                       mbits = 1

                       port "nginx" {}

                   }

               }

            service {

              name = "nginx"

              tags = ["frontend", "dev"]

              port = "nginx"

              check {

                type = "tcp"

                interval = "5s"

                timeout = "2s"

              }

            }

}

        task "nginx" {

            driver = "docker"

            logs {

                max_files = 3

                max_file_size = 100

            }

            config {

                image = "172.16.30.80:5000/nginx:bwts"

                port_map {

                    service_port = 80

                }

            }

            resources {

                cpu = 512

                memory = 2048

                network {

                  mbits = 82

         port "service_port" {}

                }

                disk = 2048

            }

            env {

            }

        }

    }

}

when I run nomad 

root@nomad01:~# nomad run test.hcl

==> Monitoring evaluation "eba31fd3"

    Evaluation triggered by job "nginx"

    Allocation "e861342e" created: node "7a326813", group "nginx"

    Evaluation status changed: "pending" -> "complete"

==> Evaluation "eba31fd3" finished with status "complete"

I find nginx-ck is not the job that can monitor or check nginx's healthy state,because this task check 172.16.30.111:24091,and the docker is 172.16.30.111:35632,so I can't understand the working principle between these two tasks ,so can you explain it ?
