ssh - 在OpenStack中使用jclouds传递ssh key

我使用jclouds在openstack中创建服务器。尽管我能够创建服务器，但我也想传递我的公共(public)ssh密钥，以便在云初始化完成后连接到服务器。下面是我的代码。

package org.chris.jcloud;

public  class JClouds implements Closeable {
   private ComputeService compute;
   private RestContext<NovaApi, NovaAsyncApi> nova;
   private Set<String> zones;

   public static void main(String[] args) throws IOException {
      JClouds jCloudsNova = new JClouds();

      try {
         jCloudsNova.init();
         jCloudsNova.listServers();
         jCloudsNova.close();
         jCloudsNova.createServers();
      }
      catch (Exception e) {
         e.printStackTrace();
      }
      finally {
         jCloudsNova.close();
      }
   }

   private void init() {
      Iterable<Module> modules = ImmutableSet.<Module> of(new SLF4JLoggingModule());

      String provider = "openstack-nova";
      String identity = "admin:admin"; // tenantName:userName
      String password = "test"; // demo account uses ADMIN_PASSWORD too

      ComputeServiceContext context = ContextBuilder.newBuilder(provider)
            .endpoint("http://192.168.1.33:5000/v2.0/")
            .credentials(identity, password)
            .modules(modules)
            .buildView(ComputeServiceContext.class);
      compute = context.getComputeService();
      nova = context.unwrap();
      zones = nova.getApi().getConfiguredZones();
   }

   private void listServers() {
      for (String zone: zones) {
         ServerApi serverApi = nova.getApi().getServerApiForZone(zone);

         System.out.println("Servers in " + zone);

         for (Server server: serverApi.listInDetail().concat()) {
            System.out.println("  " + server);
         }
      }
   }

   private void createServers() {
    for (String zone : zones) {
        ServerApi serverApi = nova.getApi().getServerApiForZone(zone);
        CreateServerOptions sv = CreateServerOptions.Builder.adminPass("test");
        ServerCreated newServer = serverApi.create("paparia", "ab8fbee6-4907-4e59-ba77-471362bc8200", "1", sv);
    //  TemplateBuilder templateBuilder = compute.templateBuilder();
    //  Template template = templateBuilder.options(authorizePublicKey(Payloads.newPayload(new File("/home/me/.ssh/id_rsa.pub")).toString())).build();


        System.out.println("Servers in " + zone);
        listServers();
    }
}

@Override
public void close() throws IOException {
    // TODO Auto-generated method stub

}



   /*public void close() {
      closeQuietly(compute.getContext());
   }*/
}

最佳答案

我不知道如何在客户端运行时指定新密钥，但是要使用预先上传到Openstack的预定义公共(public)密钥，请使用method

CreateServerOptions.Builder.keyPairName(KEY_NAME)

可在Openstack仪表板的“访问和安全”>“密钥对”中找到公用密钥列表。我实际上不确定，是否可以为实例指定新密钥，因为用于手动实例创建的仪表板表单不支持新密钥上传。但是，它导入了一个新的NAMED密钥，在创建该实例之后，该密钥被添加到上述公共(public)密钥列表中。
