Test Mesos DNS¶

to test our Mesos DNS setup, we will start a new application and check if it automatically gets a DNS name.

Start a new app in marathon:

{
  "id": "app-test-dns",
  "cpus": 0.5,
  "mem": 32.0,
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "eboraas/apache-php",
      "network": "BRIDGE",
      "portMappings": [
        { "containerPort": 80, "hostPort": 0 }
      ]
    }
  }
}

Once it’s running, go to one of your slaves and run ping app-test-dns.marathon.mesos. It should work

If you don’t try to ping from Slave1 or slave2, make sure that your client reach our mesos-dns server first (10.2.10.40)
