GCP API客户端库Java示例-com.google.API.services.deploymentmanager.

Question

我希望使用Deployment Manager自动配置谷歌云资源。只有我想使用JAVA API库而不是gcloud。

特别需要使用DeploymentManager配置以下组件。

1. 云SQL-MSSQL
2. 云运行服务
3. VPC网络，带有用于将Cloud Run连接到Cloud SQL的连接器

我认为com.google.api.services.deploymentmanager.DeploymentManager是起点，但我不太确定。

这就是我目前拥有的

Builder builder = new Builder(
com.google.api.client.googleapis.javanet.GoogleNetHttpTransport.newTrustedTransport(),
new com.google.api.client.json.gson.GsonFactory(), null);
builder.setApplicationName("spatial-cat-319209");
builder.setDeploymentManagerRequestInitializer(new DeploymentManagerRequestInitializer());
DeploymentManager deploymentManager = builder.build();
deploymentManager.deployments().list("spatial-cat-319209").entrySet().stream().forEach(entry -> {
System.out.println(entry.getKey() + " = " + entry.getValue());
});

System.out.println(System.getProperty("GOOGLE_APPLICATION_CREDENTIALS"));
System.out.println(System.getenv("GOOGLE_APPLICATION_CREDENTIALS"));

deploymentManager.deployments().list("spatial-cat-319209").execute();

我在最后一行中得到以下错误：

我的环境变量GOOGLE_APPLICATION_CREDENTIALS指向一个文件，该文件包含服务帐户密钥(使用gcloud auth application-default login命令生成(

任何见解都会很有帮助。

Answer 1

好吧，看起来我已经使用了下面的代码。

我已经演示了如何使用processbuilder和DeploymentManagerneneneba API来使用gcloud命令。我必须使用GoogleCredentials来读取服务帐户密钥文件，并将其传递给HttpCredentialsAdapter。

很难找到，但这本指南派上了用场。发布一个链接作为后来偶然路过的人的参考。

请告诉我是否可以用更好的方式来做这件事。

GoogleCredentials googleCredentials = GoogleCredentials
.fromStream(new FileInputStream(System.getenv("GOOGLE_APPLICATION_CREDENTIALS")));
HttpRequestInitializer httpRequestInitializer = new HttpCredentialsAdapter(googleCredentials);
Builder builder = new Builder(
com.google.api.client.googleapis.javanet.GoogleNetHttpTransport.newTrustedTransport(),
com.google.api.client.json.gson.GsonFactory.getDefaultInstance(), httpRequestInitializer);
builder.setApplicationName("spatial-cat-319209");
builder.setDeploymentManagerRequestInitializer(new DeploymentManagerRequestInitializer());
DeploymentManager deploymentManager = builder.build();
deploymentManager.deployments().list("spatial-cat-319209").entrySet().stream().forEach(entry -> {
System.out.println(entry.getKey() + " = " + entry.getValue());
});
System.out.println(System.getProperty("GOOGLE_APPLICATION_CREDENTIALS"));
System.out.println(System.getenv("GOOGLE_APPLICATION_CREDENTIALS"));
System.out.println("Listing deployments in project using gcloud command ...");
// Runtime.getRuntime().exec("gcloud deployment-manager deployments list");
ProcessBuilder processBuilder = new ProcessBuilder();
Process process = processBuilder.command("powershell", "gcloud", "deployment-manager", "deployments", "list")
.start();
InputStreamReader isr = new InputStreamReader(process.getInputStream());
BufferedReader rdr = new BufferedReader(isr);
String line = "";
while ((line = rdr.readLine()) != null) {
System.out.println(line);
}
isr = new InputStreamReader(process.getErrorStream());
rdr = new BufferedReader(isr);
while ((line = rdr.readLine()) != null) {
System.out.println(line);
}
int rc = process.waitFor(); // Wait for the process to complete
System.out.println("Return Code = " + rc);
System.out.println("Listing deployments in project using DeploymentManager API...");
DeploymentsListResponse deploymentsListResponse = deploymentManager.deployments().list("spatial-cat-319209")
.execute();
System.out.println("Number of deployments = " + deploymentsListResponse.size());
deploymentsListResponse.forEach((depl, a) -> System.out.println(depl + " - " + a));
System.out.println("Done");
