在openstack中使用jclouds傳遞ssh密鑰

我使用jclouds在openstack中創建服務器。雖然我能夠創建服務器，但我還想傳遞公共ssh密鑰以便在完成雲初始化後連接到服務器。以下是我的代碼。在openstack中使用jclouds傳遞ssh密鑰

從我可以看到，它看起來像模板被註釋掉，將添加公鑰。其次，模板需要在創建調用期間使用。 ['createNodesInGroup'將採用您製作的模板]（https://github.com/jclouds/jclouds-examples/blob/f5f038cc4c92c85fb8bc61c7ca8a591b7b2dacad/rackspace/src/main/java/org/jclouds/examples/rackspace/cloudservers/CreateServer。 Java的＃L97-L106）。 –

我不知道，你怎麼可以指定客戶端運行時新的密鑰，而是使用預定義的公共密鑰，之前上傳到OpenStack的，使用方法

CreateServerOptions.Builder.keyPairName(KEY_NAME)

公鑰的列表可在Openstack儀表板的「Access &安全」>「Keypairs」中。實際上，我不確定是否可以爲實例指定新的密鑰，因爲手動實例創建的儀表板表單不支持新的密鑰上傳。它有一個新的NAMED鍵的導入，但是，在創建實例後，它會添加到上面提到的公鑰列表中。
