Deploying on Nomad

Deploying Pulse Agent on a Nomad cluster is simple. Here is a sample job spec that will deploy just the Pulse Agent, however it would also be possible to place the task into the same job as your existing cluster job.

job "pulse_agent" {
  datacenters = ["dc1"]
  type = "service"
  priority = 50

  update {
    canary = 1
    auto_promote = true
  }

  group "main" {
    network {
      port "agent_healthz" {
        to = 8080
      }
    }

    task "agent" {
      driver = "docker"
      config {
        image = "r.bigdataboutique.com/pulse-agent"
        ports = ["agent_healthz"]

        volumes = [
          "secrets/config.yml:/etc/pulse-agent/pulse-agent-config.yml",
        ]
      }

      template {
        destination = "secrets/config.yml"
        data = <<-EOF
          environmnet: default
          pulseToken: PULSE_TOKEN

          clusters:
          - type: kafka
              bootstrap.servers: PLAINTEXT://hostname:9092
          - type: elasticsearch
              hosts: http://hostname:9200
              username: pulse-monitoring-collector
              password: pwd
          EOF
      }

      resources {
        cpu = 100
        memory = 16384
      }

      service {
        name = "pulse-agent"
        port = "agent_healthz"
        provider = "nomad"

        check {
          type     = "http"
          path     = "/healthz"
          interval = "30s"
          timeout  = "2s"
        }
      }
    }
  }
}

Assuming you use this job spec and save it as pulse_agent.nomad, then upload the job spec to your Nomad cluster:

nomad job run pulse_agent.nomad
