Scape $ on variable substitution to deploy app json to marathon

[kikicarbonell]

I'm trying to deploy one app to marathon and my json has some internal variable managed by marathon like: $HOST, $PORT0 and $PORT1, but depcon try to replace with instance variable when upload file and show some errors....I need a way to scape these variable...

My app.json:

{
  "id": "appname",
  "cpus": "0.1",
  "mem": "256",
  "instances": 1,
  "cmd": "./bin/spark-class org.apache.spark.deploy.mesos.MesosClusterDispatcher --master zk://localhost:2181/mesos --zk localhost:2181 --host $HOST --port $PORT0 --webui-port $PORT1 --name spark_marathon_framework_name",
  "env": {
    "SPARK_USER": "root",
    "HADOOP_HOME": "/usr/lib/hadoop"
  },
  "ports": [
    32000,
    0
  ],
  "container": {
    "type": "DOCKER",
    "docker": {
      "image": "registry/myimage:latest",
      "network": "HOST"
    },
    "volumes": [
      {
        "containerPath": "/etc/localtime",
        "hostPath": "/etc/localtime",
        "mode": "RO"
      },
      {
        "containerPath": "/etc/hadoop/conf",
        "hostPath": "spark_marathon_hadoop_conf_dir",
        "mode": "RO"
      },
      {
        "containerPath": "/usr/lib/hadoop",
        "hostPath": "/usr/lib/hadoop",
        "mode": "RO"
      }
    ]
  },
  "healthChecks": [
    {
      "path": "/",
      "portIndex": 1,
      "protocol": "HTTP",
      "gracePeriodSeconds": 5,
      "intervalSeconds": 60,
      "timeoutSeconds": 10,
      "maxConsecutiveFailures": 3
    }
  ], "_hack": null
}

Good find. Since depcon uses ${PARAM} format your correct. We should treat $PARAM without the {} as a non-depcon param (leave as is). Will look into addressing this in the next 24 hours.

Ok, should be fixed. I updated the binaries now version 0.5. Also the ^^ JSON above is malformed, found another bug in not reporting this. The CPU and Mem are numeric and should have "0.1" in quotes.

Let me know if this fix works for you for issue closure
