DCOS Agent Node Attributes

Attributes can be defined for each agent node type. The attributes can then be used with Marathon deployments as placement contraints.

Attributes can easily be defined in AgentPoolProfile property of the API Model

The definition below adds 2 attributes "foo" and "att1" to all nodes in the agentprivate pool.

    "agentPoolProfiles": [
      {
        "name": "agentprivate",
        "count": 3,
        "vmSize": "Standard_D2_v2",
        "customNodeLabels" : {
          "foo" : "bar",
          "att1" : "value1"
        } 
      }
    ]

You can confirm the attributes on the Node Details:
