I am looking to automate the provisioning of google cloud resources using Deployment Manager. Only I want to use the JAVA API library instead of gcloud.
Specifically need to provision the following components using DeploymentManager.
I think com.google.api.services.deploymentmanager.DeploymentManager is the starting point but I am not very sure.
This is what I have so far
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();
I get the following error in the last line:
Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 Unauthorized

I do have the environment variable GOOGLE_APPLICATION_CREDENTIALS pointing to a file that contains the service account key (generated using gcloud auth application-default login command)
Any insights would be very helpful.
Okay, it looks like I have got it working with the code below.
I have demonstrated how to use gcloud command using processbuilder as well as the DeploymentManager API. I had to use GoogleCredentials to read the service-account-key-file and pass that to the HttpCredentialsAdapter.
It was very hard to locate but this guide came in handy. Posting a link as reference for someone who stumbles by later.
Let me know if this can be done in a better way.
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");
