com.google.cloud.storage.StorageException: 401 Unauthorized

I am trying to get this sample working without success

I installed and initialized the client:

export CLOUD_SDK_REPO="cloud-sdk-$(lsb_release -c -s)"

echo "deb https://packages.cloud.google.com/apt $CLOUD_SDK_REPO main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list

curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -

sudo apt-get update \
    && sudo apt-get -y install google-cloud-sdk \
    && sudo apt-get -y install google-cloud-sdk-app-engine-java \
    && sudo apt-get -y install google-cloud-sdk-app-engine-python \

gcloud init

Then I authenticated successfully:

gcloud auth activate-service-account [email protected] --key-file=DockerStorage-e7def0adcafb.json

Then I tried the quick start sample:

Storage storage = StorageOptions.getDefaultInstance().getService();
String bucketName = "my-first-bucket";  // "my-new-bucket";
Bucket bucket = storage.create(BucketInfo.of(bucketName));
System.out.printf("Bucket %s created.%n", bucket.getName());

BOOM unauthorized

Exception in thread "main" com.google.cloud.storage.StorageException: 401 Unauthorized

What did I miss?

At first, You have to a generate a Service account credential.

Generating a service account credential To generate a private key in JSON or PKCS12 format:

  1. Open the list of credentials in the Google Cloud Platform Console. Google Cloud Platform Console
  2. Click Create credentials.
  3. Select Service account key.
  4. A Create service account key window opens.
  5. Click the drop-down box below Service account, then click New service account.
  6. Enter a name for the service account in Name.
  7. Use the default Service account ID or generate a different one.
  8. Select the Key type: JSON or P12.
  9. Click Create.

Then simply use the credential json file in you code. 

    StorageOptions storageOptions = StorageOptions.newBuilder()
       .setProjectId("YOUR_PROJECT_ID")
        .setCredentials(GoogleCredentials.fromStream(new 
         FileInputStream("path/YOUR_SERVICE_ACCOUNT_CRENDENTIAL.json"))).build();
    Storage storage = storageOptions.getService();

Hrm...good question. Theoretically this should work If you don't otherwise specify auth, that library will first attempt to use the credentials file specified by the GOOGLE_APPLICATION_CREDENTIALS environment variable, and if that's not set, it should go looking for your gcloud credentials.

I'm guessing that it can't find your gcloud credentials for some reason. By default, they'll be in the ".config/gcloud" directory under your home directory, but that can be overridden. Maybe check to see if there're some files there?

One thing worth trying is simply copying a service account's JSON file to that machine and specifying the path to it with the GOOGLE_APPLICATION_CREDENTIALS environment variable. That shouldn't be necessary, but if that fails as well, something more interesting is going on.
