如何在 Java 中启动一个新的 openstack 实例？

Question

我试图通过参考下面 URL 在 Java 中启动新的 open-stack 实例。

这是我的 createInstance 方法的样子：-

public void createInstance(String instanceName) {
    for (String region : regions) {
        ServerApi serverApi = novaApi.getServerApi(region);
        System.out.println("server api : " + serverApi.toString());
        String imageId = "7d246e9a-dd2a-4342-97f7-32accd0f9c35";
        String flavorId = "8041379d-7261-401d-90cf-e2d97184fe94";

        /*Launch an instance*/
        ServerCreated ser = serverApi.create(instanceName, imageId, flavorId);

        Server server = serverApi.get(ser.getId());
        while (server.getStatus().value().equals("ACTIVE") == false) {
            try {
                Thread.sleep(1000);
            } catch (InterruptedException ex) {
            }
            server = serverApi.get(ser.getId());
        }

        System.out.println(ser.getId());
    }
}

我收到 HttpResponseException，但能够获取图像 ID、风味 ID 等

exception : org.jclouds.http.HttpResponseException: command: POST http://192.168.1.224:8774/v2/e02b6387fa5a4b619bc2ba554661ea99/servers HTTP/1.1 failed with response: HTTP/1.1 400 Bad Request; content: [{"badRequest": {"message": "Multiple possible networks found, use a Network ID to be more specific.", "code": 400}}]

您必须指定用于启动实例的风格、图像和网络。我看到你已经指定了风味和图像。但是，您还必须指定要使用的网络。检查下面的答案 link
