Question

我使用托盘返回ec2节点列表。我想得到这些的DNS名称。我在jclouds中看到有一个dnsName方法，但我认为无法访问它以便在clojure中使用托盘。这可能吗？

详情

我正在尝试修改storm-deploy项目以使用dns名称，以便安全组正常工作。具体来说，我正在尝试编写类似这个函数的东西在代码中使用：

(defn zookeeper-dns-names [compute name]
  (let [running-nodes (filter running?
    (map (partial jclouds-node->node compute) (nodes-in-group compute (str "zookeeper-" name))))]
    (map dns-name running-nodes)))

我在我们的托盘部署中使用它，它通过公共IP获取dns名称：

(defn get-aws-name []
  (let [ip (-> (target-node) bean :publicAddresses first)]
    (str "ec2-" (apply str (replace {\. \-} ip)) ".compute-1.amazonaws.com")))

私有IP也可以通过安全组工作：

(defn ips-in-group [group-name public-or-private]
  "Sequence of the first public IP from each node in the group"
  (->> (nodes-in-group group-name)
       (map bean)
       (map public-or-private)
       (map first))

(defn public-ips-in-group
  "Sequence of the first public IP from each node in the group"
  [group-name]
  (ips-in-group group-name :publicAddresses))

(defn private-ips-in-group
  "Sequence of the first public IP from each node in the group"
  [group-name]
  (ips-in-group group-name :privateAddresses))
